Airworthiness Directives; Bombardier, Inc. Model DHC-8-400 Series
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:

    Bombardier Aerospace has completed a system safety review of the
aeroplanes fuel system against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043 [which corresponds with the FAA's
Special Federal Aviation Regulation (SFAR) 88]. The identified non-
compliances were then assessed using Transport Canada Policy Letter
No. 525-001, to determine if mandatory corrective action is
required.
    The assessment showed that a number of modifications to the fuel
system are required to mitigate unsafe conditions that could result
in potential ignition source within the fuel system.

    The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2010-31, dated September 3, 2010 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:

    Bombardier Aerospace has completed a system safety review of the
aeroplanes fuel system against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043 [which corresponds with the FAA's
Special Federal Aviation Regulation (SFAR) 88]. The identified non-
compliances were then assessed using Transport Canada Policy Letter
No. 525-001, to determine if mandatory corrective action is
required.
    The assessment showed that a number of modifications to the fuel
system are required to mitigate unsafe conditions that could result
in potential ignition source within the fuel system.

    The Bombardier modifications include:
     Modsum 4-126330, ``Fuel Tank System Design Left and Right
Side (SFAR 88) Retrofit.'' The retrofit includes replacing certain
fittings, couplings, o-rings, gaskets, fuel adapter, and other related
components with new, improved parts; applying alodine 1132 to certain
areas of a wing rib and a wing spar; and replacing a certain doubler on
the front wing spar with a new, improved doubler.
     Modsum 4-126366, ``Fuel Tank System and Fuel Indication--
Wiring Identification, Segregation and

Installation (High Level Sensor and Fuel Quantity Indication)--
Retrofit.'' The retrofit includes adding new wiring with protective
sleeving, reworking existing wiring, labeling and separating the fuel
quantity indicating (FQI) wiring and high level sensor wiring from
other wiring, enhancing the electro-magnetic interference (EMI)
shielding of the wiring connected to the vent valve position switch,
and installing additional provisions (bulkhead brackets) for wiring
clips in the center fuselage.
     Modsum 4-901425, ``Fuel Feed to APU--Replacement of
Couplings in Center Wing Left Side--SFAR 88.''
     Modsum 4-126370, ``Fuel Tank System--Enhance Protective
Covering for Electrical Cable Assembly,'' which includes reworking the
contact area on the rib at Yw-42.000 to ensure adequate electrical
bonding, installing spiral wrap on certain cable assemblies where
existing spiral wrap does not extend 4 inches past the tie mounts,
applying a dome seal on thread openings on a high level sensor, and
installing fuel grommets at certain locations.
     Modsum 4-113580, ``Fuel Indication--High Level Sensor--
Application of Sealant to exposed end of Sensor Terminal Block Screws--
Special Inspection and Rectification,'' which includes doing a detailed
inspection of the high level sensor for correct sealant coverage (`dome
seal') on the terminal screws, and applying sealant if necessary.
    You may obtain further information by examining the MCAI in the AD
docket.
    The FAA has examined the underlying safety issues involved in fuel
tank explosions on several large transport airplanes, including the
adequacy of existing regulations, the service history of airplanes
subject to those regulations, and existing maintenance practices for
fuel tank systems. As a result of those findings, we issued a
regulation titled ``Transport Airplane Fuel Tank System Design Review,
Flammability Reduction and Maintenance and Inspection Requirements''
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards
for transport airplanes and new maintenance requirements, this rule
included Special Federal Aviation Regulation No. 88 (``SFAR 88,''
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e.,
type certificate (TC) and supplemental type certificate (STC)) holders
to substantiate that their fuel tank systems can prevent ignition
sources in the fuel tanks. This requirement applies to type design
holders for large turbine-powered transport airplanes and for
subsequent modifications to those airplanes. It requires them to
perform design reviews and to develop design changes and maintenance
procedures if their designs do not meet the new fuel tank safety
standards. As explained in the preamble to the rule, we intended to
adopt airworthiness directives to mandate any changes found necessary
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four
criteria intended to define the unsafe conditions associated with fuel
tank systems that require corrective actions. The percentage of
operating time during which fuel tanks are exposed to flammable
conditions is one of these criteria. The other three criteria address
the failure types under evaluation: single failures, single failures in
combination with a latent condition(s), and in-service failure
experience. For all four criteria, the evaluations included
consideration of previous actions taken that may mitigate the need for
further action.
    We have determined that the actions identified in this AD are
necessary to reduce the potential of ignition sources inside fuel
tanks, which, in combination with flammable fuel vapors, could result
in fuel tank explosions and consequent loss of the airplane.

Relevant Service Information

    Bombardier has issued Service Bulletins:
     84-57-09, Revision B, dated September 3, 2008;
     84-28-04, Revision B, dated October 21, 2009;
     84-28-05, dated June 28, 2006;
     84-28-03, Revision C, dated May 15, 2009; and
     84-28-07, dated August 1, 2008.
    Bombardier has also issued Fuel Systems Limitation (FSL) Task
284000-417 in Section 4-1, Fuel System Limitations, of Part 2--
Airworthiness Limitation Items, Revision 5, dated April 21, 2010, of
Bombardier Q400 Dash 8 Maintenance Requirements Manual, PSM 1-84-7.
    The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD
would affect about 67 products of U.S. registry. We also estimate that
it would take about 526 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about $37,696 per product. Where
the service information lists required parts costs that are covered
under warranty, we have assumed that there will be no charge for these
costs. As we do not control warranty coverage for affected parties,
some parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $5,521,202, or $82,406 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
    We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations

for practices, methods, and procedures the Administrator finds
necessary for safety in air commerce. This regulation is within the
scope of that authority because it addresses an unsafe condition that
is likely to exist or develop on products identified in this rulemaking
action.

Regulatory Findings

    We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information
as follows: The MCAI specifies to do Bombardier FSL Task 28400-417,
but does not specify what to do if the functional check finds that
measured resistance exceeds the specified values. This AD requires
contacting the Manager, New York ACO, FAA, or TCCA (or its delegated
agent) for repair/rework instructions.

Other FAA AD Provisions

    (o) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, ANE-
170, New York ACO, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to Attn: Program Manager, Continuing Operational Safety,
FAA, New York ACO, 1600 Stewart Avenue, Suite 410, Westbury, New
York 11590; telephone<PHONE_NUMBER>; fax<PHONE_NUMBER>. Before using
any approved AMOC, notify your appropriate principal inspector, or
lacking a principal inspector, the manager of the local flight
standards district office/certificate holding district office. The
AMOC approval letter must specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. Subtitle I, Section 106
describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the agency's
authority. This rulemaking is promulgated under the authority described
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section,
the FAA is charged with prescribing regulations to assign the use of
airspace necessary to ensure the safety of aircraft and the efficient
use of airspace. This regulation is within the scope of that authority
as it amends Class D airspace and Class E airspace extending upward
from 700 feet above the surface at Lawrence J. Timmerman

Airport, Milwaukee, WI, to support IFR operations at this airport.

History

    The FAA published a notice of proposed rulemaking in the Federal
Register (83 FR 51895; October 15, 2018) for Docket No. FAA-2018-0829
to amend Class D airspace and Class E airspace extending upward from
700 feet above the surface at Lawrence J. Timmerman Airport, Milwaukee,
WI. Interested parties were invited to participate in this rulemaking
effort by submitting written comments on the proposal to the FAA. No
comments were received.
    Subsequent to publication, the FAA discovered typographic errors in
the airspace legal descriptions as follows:
    The airport latitude coordinate in the Class D airspace legal
description should be ``43[deg]06'37'' N.'' vice ``43[deg]06'39'' N.'';
    The radius in the Class D airspace legal description should be a
``3.9-mile radius'' vice a ``4.4-mile radius'';
    And the extensions in the Class E airspace extending upward from
700 feet above the surface airspace legal description at Lawrence J.
Timmerman Airport, Milwaukee, WI, should be, ``. . . and within 2 miles
each side of the 218[deg] bearing from the Lawrence J. Timmerman
Airport extending from the 6.4-mile radius to 11.7 miles southwest of
Lawrence J. Timmerman Airport, and within 9 miles west and 6 miles east
of the 328[deg] bearing from the Lawrence J. Timmerman: RWY15L-LOC
extending from the 6.4-mile radius to 10 miles northwest of the
Lawrence J. Timmerman Airport.'' vice ``. . . and within 2 miles each
side of the 218[deg] bearing from the Lawrence J. Timmerman Airport
extending from the 6.4-mile radius to 11.7 miles northwest of Lawrence
J. Timmerman Airport, and within 9 miles west and 6 miles east of the
328[deg] bearing from the Lawrence J. Timmerman: RWY15-LOC extending
from the 6.4-mile radius to 10 miles from the Lawrence J. Timmerman
Airport.''
    These errors have been corrected in this final rule.
    Class D and E airspace designations are published in paragraph 5000
and 6005, respectively, of FAA Order 7400.11C, dated August 13, 2018,
and effective September 15, 2018, which is incorporated by reference in
14 CFR 71.1. The Class D and E airspace designations listed in this
document will be published subsequently in the Order.

Availability and Summary of Documents for Incorporation by Reference

    This document amends FAA Order 7400.11C, Airspace Designations and
Reporting Points, dated August 13, 2018, and effective September 15,
2018. FAA Order 7400.11C is publicly available as listed in the
ADDRESSES section of this document. FAA Order 7400.11C lists Class A,
B, C, D, and E airspace areas, air traffic service routes, and
reporting points.

The Rule

    This amendment to Title 14 Code of Federal Regulations (14 CFR)
part 71 modifies:
    Class D airspace to within a 3.9-mile radius (reduced from a 4.4-
mile radius) of Lawrence J. Timmerman Airport, Milwaukee, WI; and
updates the airspace designation from ``Milwaukee, Lawrence J.
Timmerman Airport, WI'' to ``Milwaukee, WI'', removes the city from the
airport name, and makes an editorial change replacing ``Airport/
Facility Directory'' with ``Chart Supplement'' to comply with FAA Order
7400.2L, Procedures for Handling Airspace Matters; and
    Class E airspace extending upward from 700 feet above the surface
to within a 6.4-mile radius (reduced from an 8.9-mile radius) of
Lawrence J. Timmerman Airport, Milwaukee, WI; adds an extension within
2 miles each side of the 218[deg] bearing from Lawrence J. Timmerman
Airport extending from the 6.4-mile radius to 11.7 miles southwest of
the airport; adds an extension within 9 miles west and 6 miles east of
the 328[deg] bearing from the Lawrence J. Timmerman: RWY 15L-LOC
extending from the 6.4-mile radius to 10 miles northwest of the
airport.
    This action is necessary due to an airspace review caused by the
decommissioning of the Timmerman VOR, which provided navigation
information for the instrument procedures at these airports, as part of
the VOR MON Program.
    The typographic errors in the airspace legal descriptions have been
corrected in this rule. Except for these corrections, this rule is the
same as published in the NPRM.

Regulatory Notices and Analyses

    The FAA has determined that this regulation only involves an
established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current, is
non-controversial and unlikely to result in adverse or negative
comments. It, therefore: (1) Is not a ``significant regulatory action''
under Executive Order 12866; (2) is not a ``significant rule'' under
DOT Regulatory Policies and Procedures (44 FR 11034; February 26,
1979); and (3) does not warrant preparation of a regulatory evaluation
as the anticipated impact is so minimal. Since this is a routine matter
that only affects air traffic procedures and air navigation, it is
certified that this rule, when promulgated, does not have a significant
economic impact on a substantial number of small entities under the
criteria of the Regulatory Flexibility Act.

Environmental Review

    The FAA has determined that this action qualifies for categorical
exclusion under the National Environmental Policy Act in accordance
with FAA Order 1050.1F, ``Environmental Impacts: Policies and
Procedures,'' paragraph 5-6.5.a. This airspace action is not expected
to cause any potentially significant environmental impacts, and no
extraordinary circumstances exist that warrant preparation of an
environmental assessment.

 BILLING CODE 6717-01-P


This document is designed to help one use the input files provided by
EPA in HD GHG NPRM docket to run MOVES to produce the output EPA used to
developed emission inventories for all the HD GHG alternatives.

Code

The version of the MOVES code used is 2009-12-21.  This should be
available on the MOVES website as MOVES2010.

Default database

MOVESDB20100515 was used at the default database.  This should be
available on the MOVES website if not already part of the installation
package.

Input databases

The input databases are used to change the default data in MOVES to
reflect HD GHG rule alternatives.  These databases are:

HDGHG_reference_20100426

HDGHG_control_20100618_reboundA

HDGHG_LHD45control_20100618_reboundA

HDGHG_eisAlt2_20100707_reboundA

HDGHG_eisAlt5_20100707_reboundA

HDGHG_epaALT8_20100812_reboundA

HDGHG_LHD45epaALT8_20100812_reboundA

The samplevehiclepopulation table also needed to be modified to reflect
proper sales and fleet distributions of the different segments of
trucks.  However, the version of MOVES we ran does not allow for this
table to be used in an input database.  As a result, new default
databases were created containing the updated samplevehiclepopulation
table.  These modified default databases are:

MOVESDB20100515_MHDHHD2b3

MOVESDB20100515_45

MOVESDB20100515_eisAlt3HHD

MOVESDB20100515_eisAlt3MHD

These modified default databases work in concert with any input
databases specified in the run spec.

Run Specs

Twenty-eight run specs are included.  Seventeen runs are for the
non-GHGs and GHGs for calendar years 2005, 2018, 2030, and 2050.  Eleven
runs are for annual GHGs from 2014 through 2050.  CO2 and CO2eq were not
explicitly run.  Instead, total energy consumption was run and
post-processed to calculate CO2 (by fuel), and methane and N2O were run
separately.

The run specs should already call up the appropriate modified default
databases and user input databases, so no additional changes need to be
made to the run specs, provided the names of the databases are
unchanged.  Feel free to edit the name of the output databases to better
suit your need.

Air toxics are included in the gasoline runs, but not for diesel runs.
Air toxics are post-processed for diesel vehicles.  This version of
MOVES code is especially slow if running air toxics.

The batch file named “HDGHG_2005-2018-2030-2050-Annual_20100816.bat”
initiates MOVES and queues up all of the run specs.  To save time, this
batch file can be split up into two or more batch files and run on
separate computers.  You will likely need to edit the batch file so that
the file paths for MOVES and the run specs match the locations on your
local hard drives.

Not all alternatives were run explicitly in MOVES.  Some alternatives
are subsets of the alternatives run in MOVES and were therefore
post-processed.

Post-processing

Post-processing was a necessary component to the inventory development
for the following items:

Using reference inventories and activity for pre-rule model years

APU emission rates for extended idling for combination long-haul trucks

Diesel air toxics

Combining MOVES runs to produce inventories for all alternatives

Post-processing was done using SAS software.  Other software can be used
to post-process if desired, but only SAS code is included.  The included
SAS code should automate most of the post-processing.

First, you must export both the four-year and annual MOVES emissions
output (movesoutput table) and activity output (movesactivityoutput
table) into four different CSV files.  This can be done by executing the
following code in mySQL:

Emissions: select movesrunID, yearID, pollutantID, processID,
fueltypeID, sourcetypeID, modelyearID, emissionquant FROM
`hdghgoutputnprm_20100722`.`movesoutput`;

Activity: select movesrunID, yearID, fueltypeID, sourcetypeID,
modelyearID, activitytypeID, activity from
hdghgoutputnprm_20100722.movesactivityoutput;

(execute these for both the four-year and annual output databases; then
export to CSV (e.g. through query browser GUI))

Next, in the SAS code, you must modify the file paths to import the
MOVES output CSV files data from the proper location and to the desired
location on your hard drive.

Then, in SAS, highlight all the text in the file and run.  This should
complete the post-processing.  All pollutants in the NPRM inventories
should be represented accurately.  Certain other pollutants may be
incomplete or extraneous (e.g. NMHC).  Both the annual and four-year
runs will be in a single file.  You can separate this if you wish.

Quality Modeling: DVD.”  This memo describes the contents of the DVD
and provides an overview of how these models were used to generate the
onroad and nonroad downstream inventories.

Description of the inventory production process

Onroad

For onroad mobile sources except motorcycles, EPA executed an internal
draft version of MOVES dated 8/25/2009 (MOVES20090825), which is similar
to Draft MOVES2009 with a number of improvements to the fuel effects
data and code.  This version of MOVES used default database
MOVESDB20090902NoFuelSupply.  A slightly later version, MOVES20091113,
was run for evaporative runs to correct a bug in the code that processed
evaporative emissions.  This version of MOVES used default database
MOVESDB20091109NoFuelSupply.  The database names have the suffix
“NoFuelSupply” because the fuel supply tables in both were truncated
to allow for the use of a user-supplied fuel supply table.
User-supplied fuel and temperature tables were used for these runs.
2005 fuels were those generated by the 2005 NEI process, in which EPA
county-level estimates were updated by states and local agencies.  2030
reference case fuels were estimated as those developed for the AEO case
of the RFS2 rule.  2030 control case fuels were estimated as 100% E10.
Historical temperature and humidity data for 2005 were used for all
years.  For motorcycles, we relied on the MOBILE6.2 model as run using
the NMIM platform with county-specific fuel properties and temperatures.
 MOVES supplied all pollutants except SO2 and NH3, which came from NMIM
runs.  Onroad inventories were generated by multiplying MOVES emission
factors by VMT developed for the Office of Air Quality Planning and
Standards's 2002 Version 3 Modeling Platform (PF02v3) and used in the
recently published Locomotive-Marine Rule.  This VMT, which was based on
AEO2006, was adjusted to match the annual VMT from AEO2009, but with
county allocations preserved.  AEO2009 growth factors from 2005 to 2030
were applied to 2005 NEI VMT using the three AEO categories: light duty,
commercial light trucks and heavy duty.  Assignments to MOBILE6
categories are straightforward except for Commercial Light Trucks, which
are only gasoline in the AEO classification.  The MOBILE6 Model was
M6203ChcOxFixNMIM, a special version that includes cold-start VOC and
the cold-start controls of the Mobile Source Air Toxics Rule that go
into effect in 2011 and used in the recently published Locomotive-Marine
rule. Onroad emissions generated at the state-month level from MOVES
were distributed to the county-month level using the results from
MOBILE6 as run by NMIM.

Nonroad

Nonroad equipment except for aircraft, locomotives, and commercial
marine vessels was modeled with the latest publically released NONROAD
version NONROAD2008a. This version of the NONROAD includes the benefits
of the two nonroad regulations published in 2008 (the Locomotive and
Marine Rule and the Small Spark-Ignition And Recreational Marine Engine
Rule) plus all previous nonroad regulations.

The MOVES runs produced emission factors at the state-month level for
all onroad gasoline vehicles except motorcycles.  Onroad gasoline
inventories were generated by multiplying MOVES emission factors by VMT
developed for this rule.

MOVES was used for onroad gasoline emission factors because of
significant improvements compared with MOBILE6.  Because of difficulty
with MOVES VMT allocation, MOVES was used as an emission factor model
and VMT was applied at the state-month-SCC level. For 2005, the VMT came
from the 2005 NEI.  For 2030, light-duty VMT came from modeling done for
this rule and was applied by state, month, SCCVtype, and model year.
Because of performance limitations of MOVES, there was only time to run
it at the state-month level.  State inventories were allocated to the
county-month level based on NMIM’s MOBILE6 runs.  Despite the
limitations of these methods, it was EPA’s judgment that they provided
superior inventories to MOBILE6.

Both MOBILE6 and NONROAD were run using NMIM (version NMIM20090504) with
NMIM County Database NCD20090710LGR.  NMIM supplied emissions from the
NONROAD Model and from onroad sources not produced from MOVES. The
MOBILE6 Model was M6203ChcOxFixNMIM, a special version that  includes
cold-start VOC and the cold-start controls of the Mobile Source Air
Toxics Rule that go into effect in 2011. The NONROAD Model version was
the publically released version NR08a.

Onroad emissions generated at the state-month level from MOVES were
distributed to the county-month level using the results from MOBILE6 as
run by NMIM.

Onroad gasoline PM was run by MOVES at 72F and adjusted by OAQPS at the
grid-hour level based on temperature curves supplied by OTAQ.

For diesel, MOVES did not calculate toxics from VOC correctly, so we
post-processed VOC to get these toxics using toxic/VOC ratios developed
by Rich Cook.  The table below shows the toxic/VOC ratio by SCCVtype.

approval. At that time, EPA will issue another Federal Register notice
to announce the submission of the ICR to OMB and the opportunity to
submit additional comments to OMB.
    Abstract: In accordance with the regulations at 40 CFR 79, subparts
A, B, C, and D, Registration of Fuels and Fuel Additives, manufacturers
(including importers) of motor-vehicle gasoline, motor-vehicle diesel
fuel, and additives for those fuels, are required to have these
products registered by the EPA prior to their introduction into
commerce. Registration involves providing a chemical description of the
fuel or additive, and certain technical, marketing, and health-effects
information. The development of health-effects data, as required by 40
CFR 79, Subpart F, is the subject of this ICR. The information
collection requirements for Subparts A through D, and the supplemental
notification requirements of Subpart F (indicating how the manufacturer
will satisfy the health-effects data requirements) are covered by a
separate ICR (EPA ICR Number 309.16, OMB Control Number

2060-0150). The health-effects data will be used to determine if there
are any products which have evaporative or combustion emissions that
may pose an unreasonable risk to public health, thus meriting further
investigation and potential regulation. This information is required
for specific groups of fuels and additives as defined in the
regulations. For example, gasoline and gasoline additives which consist
of only carbon, hydrogen, oxygen, nitrogen, and/or sulfur, and which
involve a gasoline oxygen content of less than 1.5 weight percent, fall
into a ``baseline'' group. Oxygenated additives, such as ethanol, when
used in gasoline at an oxygen level of at least 1.5 weight percent,
define separate ``non-baseline'' groups for each oxygenate. Additives
which contain elements other than carbon, hydrogen, oxygen, nitrogen,
and sulfur fall into separate ``atypical'' groups. There are similar
grouping requirements for diesel fuel and diesel fuel additives.
    Manufacturers may perform the research independently or may join
with other manufacturers to share in the costs for each applicable
group. Several research consortiums (groups of manufacturers) have been
formed. The largest consortium, organized by the American Petroleum
Institute (API), represents most of the manufacturers of baseline
gasoline, baseline diesel fuel, baseline fuel additives, and the
prominent non-baseline oxygenated additives for gasoline. The research
is structured into three tiers of requirements for each group. Tier 1
requires an emissions characterization and a literature search for
information on the health effects of those emissions. Voluminous Tier 1
data for gasoline and diesel fuel were submitted by API and others in
1997. Tier 1 data have been submitted for biodiesel, water/diesel
emulsions, several atypical additives, and renewable gasoline and
diesel fuels. Tier 2 requires short-term inhalation exposures of
laboratory animals to emissions to screen for adverse health effects.
Tier 2 data have been submitted for baseline diesel, biodiesel, and
water/diesel emulsions. Alternative Tier 2 testing can be required in
lieu of standard Tier 2 testing if EPA concludes that such testing
would be more appropriate. EPA reached that conclusion with respect to
gasoline and gasoline-oxygenate blends, and alternative requirements
were established for the API consortium for baseline gasoline and six
gasoline-oxygenate blends. Alternative Tier 2 requirements have also
been established for the manganese additive MMT manufactured by the
Afton Chemical Corporation (formerly the Ethyl Corporation). Tier 3
provides for follow-up research, at EPA's discretion, when remaining
uncertainties as to the significance of observed health effects,
welfare effects, and/or emissions exposures from a fuel or fuel/
additive mixture interfere with EPA's ability to make reasonable
estimates of the potential risks posed by emissions from a fuel or
additive. To date, EPA has not imposed any Tier 3 requirements. Under
regulations promulgated pursuant to Section 211 of the Clean Air Act,
(1) submission of the health-effects information is necessary for a
manufacturer to obtain registration of a motor-vehicle gasoline, diesel
fuel, or fuel additive, and thus be allowed to introduce that product
into commerce, and (2) the information shall not be considered
confidential.
    Form numbers: None.
    Respondents/affected entities: Manufacturers of motor-vehicle
gasoline, motor-vehicle diesel fuel, and additives for those fuels.
    Respondent's obligation to respond: Mandatory per 40 CFR 79.
    Estimated number of respondents: 2.
    Frequency of response: On occasion.
    Total estimated burden: 13,867 hours per year. Burden is defined at
5 CFR 1320.03(b).
    Total estimated cost: $1.7 million per year, includes $0.6 million
annualized capital or operation & maintenance costs.
    Changes in estimates: There is a $2 million decrease in cost. This
decrease is due to an estimated need for only one-third of the required
testing.

Quality.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)

for certain McDonnell Douglas transport category airplanes. This

proposed AD would require a one time inspection of the Rudder Pedal
torque tube assembly for minimum wall thickness and existing cracks to
determine the condition of the part. the rudder pedal for cracking. An
inspection of the torque tube assembly to determine the thickness of the
torque tube wall if necessary and, if necessary, replacing the rudder
torque tube with a new or serviceable Rudder Pedal torque tube will
insure the integrity of the system. This proposed AD is prompted by a
report of a broken rudder pedal torque tube. We are proposing this AD to
prevent failure of a rudder pedal torque tube, which could result in
partial loss of rudder control and nose wheel steering controlled by the
rudder pedal, and consequent reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by August 8, 2005.

Discussion

    We have received a report indicating that an operator found a

broken rudder pedal torque tube on a McDonnell Douglas MD-11 airplane,
after hearing a loud bang and the sound of cracking metal before losing
rudder input during a pre-flight check. The airplane had accumulated
3,313 landing cycles and 18,416 flight hours. Analysis by the operator
and airplane manufacturer revealed that the wall thickness of the torque
tube for the rudder pedal was below the minimum specifications at the
point of failure. A thin wall and the existence of a weld applied to the
outside surface of the wall during manufacture of the torque tube
contributed to its failure. Failure of a rudder pedal torque tube could
result in partial loss of rudder control and nose wheel steering
controlled by the rudder pedal, and consequent reduced controllability
of the airplane.

    The torque tube assembly for the rudder pedals on certain Model
MD-11 airplanes is identical to those on the affected Model DC-10-10 and
DC-10-10F airplanes; Model DC-10-15 airplanes; Model DC-10-30 and
DC-10-30F (KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10-40F
airplanes; Model MD-10-10F and MD-10-30F airplanes; and MD-11F
airplanes. Therefore, all of these models may be subject to the same
unsafe condition.

Relevant Service Information

    We have reviewed the following Boeing Alert Service Bulletins:

     DC10-27A236, including Appendix A and Appendix B, dated

February 17, 2005, for McDonnell Douglas Model DC-10-10 and DC-10-10F
airplanes; Model DC-10-15 airplanes; Model DC-10-30 and DC-10-30F
(KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10-40F airplanes;
and Model MD-10-10F and MD-10-30F airplanes; and

     MD11-27A083, including Appendix A and Appendix B, dated

February 17, 2005, for McDonnell Douglas Model MD-11 and MD-11F

airplanes.

    The service bulletins describe the following procedures:

     Doing a special detailed eddy current inspection of the

torque tube assembly for existing cracks the rudder pedal for cracking.

     If no cracks ing is are found, doing a special detailed

ultrasonic inspection of the torque tube assembly to determine the wall

thickness of the torque tube.

     If any cracks are found or if the wall thickness of the

torque tube is below certain limits specified in Appendix B of the

service bulletin, replacement of the torque tube with a new or
serviceable

torque tube is required .

    Accomplishing the actions specified in the service information is

intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an

unsafe condition that is likely to exist or develop on other airplanes

of this same type design. Therefore, we are proposing this AD, which

would require accomplishing the actions specified in the service

information described previously.

Costs of Compliance

    There are about 960 airplanes of the affected design in the

worldwide fleet. This proposed AD would affect about 366 airplanes of
U.S. registry. The proposed inspection would take about 16 work hours
per airplane, at an average labor rate of $65 per work hour. Based on
these figures, the estimated cost of the proposed AD for U.S. operators
is $380,640, or $1,040 per airplane.

    For Model DC-10-10 and DC-10-10F airplanes; Model DC-10-15

airplanes; Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes;
Model DC-10-40 and DC-10-40F airplanes; and Model MD-10-10F and
MD-10-30F airplanes: The proposed replacement if necessary would take
about 16 96 work hours per airplane, at an average labor rate of $65 per
work hour. Required parts would cost about $12,892 per airplane. Based
on these figures, the estimated cost of the proposed replacements is
$19,132 13,932 per airplane.

    For Model MD-11 and MD-11F airplanes: The proposed replacement if
necessary would take about 18 5 work hours per airplane, at an average
labor rate of $65 per work hour. Required parts would cost about $12,892
per airplane. Based on these figures, the estimated cost of the proposed
replacements is $14,062 13,217 per airplane.

Reasons(s) for Proposed Text/Comments:

The NPRM underestimates the number of work hours required to replace the
rudder pedal torque tube.  The Boeing Service Bulletins(SBs) show a
higher number of task hours for replacement of the rudder pedal torque
tube.  The SBs include estimates for time to gain access, remove and
replace torque tube, adjust (for MD-11), and close access.  The DC-10
requires about 96 task hours total, versus 16 shown in the NPRM.  The
MD-11 requires about 18 task hours, versus 5 shown in the NPRM.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to

issue rules on aviation safety. Subtitle I, Section 106, describes the

authority of the FAA Administrator. Subtitle VII, Aviation Programs,

describes in more detail the scope of the Agency's authority.

    We are issuing this rulemaking under the authority described in

Subtitle VII, Part A, Subpart III, Section 44701, ``General

requirements.'' Under that section, Congress charges the FAA with

promoting safe flight of civil aircraft in air commerce by prescribing

regulations for practices, methods, and procedures the Administrator

finds necessary for safety in air commerce. This regulation is within

the scope of that authority

because it addresses an unsafe condition that is likely to exist or

develop on products identified in this rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism

implications under Executive Order 13132. This proposed AD would not

have a substantial direct effect on the States, on the relationship

between the national Government and the States, or on the distribution

of power and responsibilities among the various levels of government.

    For the reasons discussed above, I certify that the proposed

regulation:

    1. Is not a ``significant regulatory action'' under Executive Order

12866;

    2. Is not a ``significant rule'' under the DOT Regulatory Policies

and Procedures (44 FR 11034, February 26, 1979); and

    3. Will not have a significant economic impact, positive or

negative, on a substantial number of small entities under the criteria

of the Regulatory Flexibility Act.

    We prepared a regulatory evaluation of the estimated costs to

comply with this proposed AD. See the ADDRESSES section for a location

to examine the regulatory evaluation.
