Clearance of a Renewed Approval of Information Collection: Alternative
Pilot Physical Examination and Education Requirements (BasicMed)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice and request for comments.

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

SUMMARY: In accordance with the Paperwork Reduction Act of 1995, FAA
invites public comments about our intention to request Office of
Management and Budget (OMB) approval to renew an information
collection. The Federal Aviation Administration Extension, Safety, and
Security Act of 2016 (FESSA) was enacted on July 15, 2016. Section 2307
of FESSA, Medical Certification of Certain Small Aircraft Pilots,
directed the FAA to ``issue or revise regulations to ensure that an
individual may operate as pilot in command of a covered aircraft''
without having to undergo the medical certification process prescribed
by FAA regulations if the pilot and aircraft meet certain prescribed
conditions as outlined in FESSA. This collection enables those eligible
airmen to establish their eligibility with the FAA.

DATES: Written comments should be submitted by April 10, 2023.

ADDRESSES: Please send written comments:
    By Electronic Docket: www.regulations.gov (Enter docket number into
search field).
    By mail: Christopher Morris, AFS-850, 800 Independence Ave. SW,

RIN 2120-AA64

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This
proposed AD was prompted by reports that excessively deep spot faces on
the front engine mounting bolt holes on the wing pylon were detected on
the production line. This proposed AD would require a one-time
inspection for clash (interference) of the three front engine mounting
bolt holes on both the left and right wing pylons, and, depending on
findings, accomplishment of applicable corrective actions, as specified
in a European Union Aviation Safety Agency (EASA) AD, which is proposed
for incorporation by reference (IBR). The FAA is proposing this AD to
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by July 17,
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

    CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to Dat
Le, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410,
Westbury, NY 11590; telephone<PHONE_NUMBER>; email [email protected]. Any
commentary that the FAA receives which is not specifically designated

Background

    EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2023-0026, dated January 30, 2023
(EASA AD 2023-0026) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus SAS Model A350-941 and A350-1041
airplanes. The MCAI states that excessively deep spot faces have been
detected on the production line on rib 1 at the level of the front
engine mount bolting. This could cause possible integration issues
between the pylon and the front engine mount, which could lead to
interference damage. This condition, if not detected and corrected,
could lead to a reduced fatigue life, which could adversely affect the
structural integrity of the airplane.
    The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
regulations.gov under Docket No. FAA-2023-1056.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0026 specifies procedures for a one-time inspection
for clash of the three pylon bolt holes at rib 1 (forward engine
attachment on pylon), on both the left and right wing pylons, and
applicable corrective actions. Corrective actions include installing
the post-mod retention bracket assembly; accomplishing a detailed
inspection and a high frequency eddy current (HFEC) inspection or a
penetrant inspection on rib 1 for damage (cracks, scratches, or erosion
of the protective coating); measuring the spot face depth and pylon
thickness and obtaining and following instructions if incorrect spot
face depth or pylon thickness at the spot face are found; and repair.
This material is reasonably available because the interested parties
have access to it through their normal course of business or by the
means identified in ADDRESSES section.

FAA's Determination

    This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with the State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
described above. The FAA is issuing this NPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified
in EASA AD 2023-0026 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2023-0026 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2023-0026 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2023-0026 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2023-
0026. Service information required by EASA AD 2023-0026 for compliance
will be available at regulations.gov under Docket No. FAA-2023-1056
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 31 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
56 work-hours x $85 per hour = $4,760........................              $0           $4,760         $147,560
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
10 work-hours x $85 per hour = $850...             $10             $860
------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in this proposed AD.

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.
    The FAA is 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

    The FAA 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

pylons.

(e) Unsafe Condition

    This AD was prompted by reports that excessively deep spot faces
on the front engine mounting bolt holes on the wing pylon were
detected on the production line. The FAA is issuing this AD to
address potential integration issues between the pylon and the front
engine mount, which could lead to interference damage. The unsafe
condition, if not addressed, could result in reduced fatigue life,
which could adversely affect the structural integrity of the
airplane.

December 20, 2022; and Airbus Service Bulletin A350-54-P008, dated
December 20, 2022.''
    (3) Where paragraph (2) of EASA AD 2023-0026 refers to
``discrepancies,'' for this AD discrepancies are any clash
(interference) between the lockplate support and rib 1 or between
the pylon bolt and the engine mount; damage (cracks, scratches, or
erosion of the protective coating); and incorrect spot face depth or
pylon thickness at the spot face.
    (4) Where paragraph (2) of EASA AD 2023-0026 specifies to
``contact Airbus for approved instructions for corrective action and
accomplish those instructions accordingly'' if discrepancies are
detected; for this AD if any cracking is detected, the cracking must
be repaired before further flight using a method approved by the
Manager, International Validation Branch, FAA; or EASA; or Airbus
SAS's EASA Design Organization Approval (DOA). If approved by the
DOA, the approval must include the DOA-authorized signature.''
    (5) This AD does not adopt the ``Remarks'' section of EASA AD
2023-0026.
    (6) Where the service information referenced in EASA AD 2023-
0026 specifies to report inspection results or findings, this AD
requires submitting information only if damage (cracks) or incorrect
spot face depth or pylon thickness at the spot face are found during

Corporation, 1600 Riviera Avenue, Suite 200, Walnut Creek, California 94596, proposing, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180, by establishing tolerances for residues of the herbicide clethodim, including its metabolites and degradates, determined by measuring only the sum of clethodim, 2-[(1E)-1-[[[(2E)-3-chloro-2-propenyl]oxy]imino]propyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one, and  its metabolites containing the 5-(2-ethylthiopropyl)cyclohexene-3-one and 5-(2-ethylthiopropyl)-5-hydroxycyclohexene-3-one moieties and their sulphoxides and sulphones, calculated as the stoichiometric equivalent of clethodim, in or on the raw agricultural commodities: Onion, bulb subgroup 3-07A at 0.2 parts per million (ppm), Vegetable, fruiting group 08-10 at 1.0 ppm, Fruit, pome group 11-10 at 0.2 ppm, Fruit, stone group 12-12 at 0.2 ppm, Berry, low growing, subgroup 13-07G, except cranberry at 3.0 ppm, Rapeseed subgroup 20A, except flax at 0.5 ppm, Sunflower subgroup 20B at 5.0 ppm, Cottonseed subgroup 20C at 1.0 ppm and Stevia at 12 ppm.  Upon establishment of the aforementioned tolerances, IR-4 proposes to remove established tolerances for residues of the herbicide clethodim in or on the raw agricultural commodities: canola at 0.5 ppm, cotton, undelinted seed at 1.0 ppm, onion, bulb at 0.2 ppm, strawberry at 3.0 ppm, and sunflower, seed at 5.0 ppm. EPA has determined that the petition contains data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated the sufficiency of the submitted data at this time or whether the data support granting of the petition. Additional data may be needed before EPA rules on the petition.
 A.  Residue Chemistry
1.   Plant metabolism.  The metabolism of clethodim is adequately understood for the purpose of granting the proposed tolerances.
2.   Analytical method.  Practical analytical methods for detecting and measuring levels of clethodim have been developed and validated in/on all appropriate agricultural commodities and respective processing fractions.  The LOQ of clethodim in the methods is 0.2 ppm, which will allow monitoring of food with residues at the levels proposed for the tolerances.
3.   Magnitude of residues.  Residue data has been submitted which adequately support the requested tolerances.

B. Toxicological Profile
A summary of the toxicological endpoints for clethodim used for human risk assessment is discussed in EPA's January 30, 2014 Clethodim Preliminary Risk Assessment for Registration Review. As noted the toxicology database for clethodim is complete and sufficient for selecting toxicity endpoints and points of departure (PODs) for risk assessment. The acute reference dose (aRfD) of 1 mg/kg/day was calculated from the NOAEL from an acute neurotoxicity study and an uncertainty factor of 100X.  The chronic reference dose (cRfD) of 0.3 mg/kg/day was calculated from the NOAEL from the carcinogenicity study in mice and an uncertainty factor of 100X.  Clethodim is not carcinogenic so a cancer assessment was not performed. The requirement for a subchronic inhalation study was waived (HASPOC, TXR 0056491,
2/20/2013).
C. Aggregate Exposure
1.   Dietary exposure.
i.	Food. An acute and chronic dietary analysis was conducted to estimate exposure to potential clethodim residues in/on all commodities with existing tolerances. As detailed in EPA's January 30, 2014 Clethodim Preliminary Risk Assessment for Registration Review, Health Effects Division conducted a conservative unrefined assessment including tolerance levels residues and 100% crop treated using DEEM version 7.81. The addition of the proposed uses to the approved uses of clethodim is expected to make a negligible incremental contribution to the dietary burden and therefore, the risk assessment has not been repeated to include these minor uses.
ii.	Drinking water. Drinking water concentrations were calculated by the Environmental Fate and Effects Division (EFED) using PRZM-GW.  The highly conservative maximum screening-level acute and chronic EDWCs (1.43 and 1.15 mg/L, respectively) from the alfalfa use pattern were used in the dietary assessment. Details can be found in EPA's January 30, 2014 Clethodim Preliminary Risk Assessment for Registration Review.
 2.	Non-dietary exposure. Clethodim is currently registered for use on several agricultural crops and a variety of non-food uses, including residential landscaped areas. Tolerances proposed in the current petition do not impact non-dietary exposure. EPA noted in its 2014 Preliminary Risk Assessment for Registration Review short term residential exposure to Clethodim may occur from ornamental plants beds, landscapes, trees, shrubs and ground cover. The results of the aggregate assessment (food, water and residential) indicate that total short-term aggregate margins of exposure (MOEs) are not of concern (i.e. an MOE >= 100) with baseline attire (shorts, short-sleeved shirt, shoes and socks).
D. Cumulative Effects
Section 408(b)(2)(D)(v) requires that the Agency must consider "available information" concerning the cumulative effects of a particular pesticide's residues and "other substances that have a common mechanism of toxicity." EPA does not have, at this time, available data to determine whether clethodim has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. For the purposes of this tolerance action, EPA has not assumed that clethodim has a common mechanism of toxicity with other substances.

E. Safety Determination
FFDCA section 408 provides that EPA shall apply an additional margin of safety, up to ten-fold, for added protection for infants and children in the case of threshold effects, unless EPA determines that a different margin of safety will be safe for infants and children. The toxicological database for evaluating prenatal and postnatal toxicity for clethodim is complete with respect to current data requirements, and there are no special prenatal or postnatal toxicity concerns for infants and children. EPA has concluded that reliable data support reduction of the FQPA Safety Factor for protection of infants and children to 1X.
1.   U.S. population. Based on EPA's January 30, 2014 Clethodim Preliminary Risk Assessment for Registration Review, Dietary Risk Estimates (Food + Drinking Water), the acute and chronic dietary (food and drinking water) exposure is estimated at 10% and 12% of the acute and chronic Population Adjusted Dose (PAD), respectively, for the general U.S. population. Aggregate exposures below 100% of the PAD are generally considered to represent a reasonable certainty of no harm to exposed populations. IR-4 concludes that there is a reasonable certainty that no harm will result to the U.S. population (or any sub-populations) by including the incremental additional exposure resulting from the proposed uses of clethodim.
2.   Infants and children.  Based on EPA's January 30, 2014 Clethodim Preliminary Risk Assessment for Registration Review, Dietary Risk Estimates (Food + Drinking Water), the acute and chronic dietary (food and drinking water) exposure is estimated at 29% and 30% of the acute and chronic PAD, respectively, for infants <1 year old, the most highly exposed subpopulation. Aggregate exposures below 100% of the PAD are generally considered to represent a reasonable certainty of no harm to exposed populations. IR-4 concludes that there is a reasonable certainty that no harm will result to the U.S. population (or any sub-populations) by including the incremental additional exposure resulting from the proposed uses of clethodim.
F. International Tolerances
The U.S. residue definition is harmonized with Codex, but not Canada. Canada's tolerance expression includes clethodim and its metabolites containing the 2-cyclohex-1-enone moiety, but does not include the sulphoxides and sulphones.
The following Codex Maximum Residue Limits (MRL) have been established for clethodim: Bean, dry at 2.0 ppm, Onion, dry bulb at 0.5 ppm, Peanut at 5.0 ppm, Potato at 0.5 ppm, Sugar beet, roots at 0.1 ppm, Sunflower, seed at 0.5 ppm and Tomato at 1.0 ppm.

Airworthiness Directives; Boeing Model 767 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Boeing Model 767 airplanes. This proposed AD would require
installing an automatic shutoff system for the auxiliary fuel tank
pump, revising the airplane flight manual (AFM) to advise the flight
crew of certain operating restrictions for airplanes equipped with an
automatic auxiliary fuel tank pump shutoff control, revising the
Airworthiness Limitations (AWLs) section of certain maintenance
documents to include new inspections of the automatic shutoff system
for the auxiliary fuel tank boost pumps, and, for certain airplanes,
installing a placard to alert the flight crew of certain fuel usage
restrictions. This proposed AD results from a design review of the fuel
tank systems. We are proposing this AD to prevent an overheat condition
outside the pump explosion-resistance area that is open to the pump
inlet, which could cause an ignition source for the fuel vapors in the
fuel tank and result in fuel tank explosions and consequent loss of the
airplane.

DATES: We must receive comments on this proposed AD by October 26,
2007.

Discussion

    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.
    Initial results from the SFAR 88 analysis show that fuel pumps that
run dry could cause an overheat condition outside the pump explosion-
resistance area that is open to the pump inlet, which could cause an
ignition source for the fuel vapors in the fuel tank.
    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

    We have reviewed Boeing Alert Service Bulletins 767-28A0083 and
767-28A0084, both Revision 1, dated April 26, 2007. The service
bulletins describe procedures for installing an automatic shutoff
system for the auxiliary fuel tank pump. The actions involve installing
new relay brackets and relays in the P36 and P37 panels, and, for
certain airplanes, in the P33 panels; changing the wiring in the
panels; and installing wiring between the panels.
    We have also reviewed Section 9, ``Airworthiness Limitations (AWLs)
and Certification Maintenance Requirements (CMRs),'' of Boeing 767
Maintenance Planning Data (MPD) Document D622T001-9, Revision March
2006. That revision adds new fuel system Airworthiness Limitations
Instruction (ALI) 28-AWL-20 to Subsection G, ``AIRWORTHINESS
LIMITATIONS--FUEL SYSTEM AWLs, of Section 9, which includes periodic
inspections of the automatic shutoff system for the auxiliary tank fuel
boost pumps to detect latent failures that could contribute to an
ignition source. That revision also adds critical design configuration
control limitation (CDCCL) 28-AWL-19, which includes a post-maintenance
inspection of certain wiring in the fuel quantity indicating system.
CDCCLs are limitation requirements to preserve a critical ignition
source prevention feature of the fuel tank system design that is
necessary to prevent the occurrence of an unsafe condition. The purpose
of a CDCCL is to provide instruction to retain the critical ignition
source prevention feature during configuration change that may be
caused by alterations, repairs, or maintenance actions. A CDCCL is not
a periodic inspection.
    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. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously. For certain airplanes, this proposed
AD would also require installing a placard to alert the flight crew of
certain fuel usage restrictions imposed by AD 2001-15-08. This proposed
AD would also allow accomplishing the AWL revision in accordance with
later revisions of the MPD as an acceptable method of compliance if
they are approved by the Manager, Seattle Aircraft Certification Office
(ACO), FAA.

Costs of Compliance

    There are about 941 airplanes of the affected design in the
worldwide fleet; of these, 414 are U.S. registered. The following table
provides the estimated costs for U.S. operators to comply with this
proposed AD. The total fleet cost could be as high as $4,655,016.

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 and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by
adding the following new airworthiness directive (AD):

Boeing: Docket No. FAA-2007-29173; Directorate Identifier 2006-NM-
283-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by October
26, 2007.

Affected ADs

    (b) Accomplishment of certain requirements of this AD terminates
certain requirements of AD 2001-15-08, amendment 39-12342.

Applicability

    (c) This AD applies to all Boeing Model 767-200, -300, -300F,
and -400ER series airplanes, certificated in any category.

Unsafe Condition

    (d) This AD results from a design review of the fuel tank
systems. We are issuing this AD to prevent an overheat condition
outside the pump explosion-resistance area that is open to the pump
inlet, which could cause an ignition source for the fuel vapors in
the fuel tank and result in fuel tank explosions and consequent loss
of the airplane.

Compliance

    (e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

    Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (m) of this AD.

Installation

    (f) Within 36 months after the effective date of this AD,
install an automatic shutoff system for the auxiliary fuel tank
pump, in accordance with Boeing Alert Service Bulletin 767-28A0083
(for Model 767-200, -300, and -300F airplanes) or 767-28A0084 (for
Model 767-400ER airplanes), both Revision 1, dated April 26, 2007;
as applicable.

Installation According to Previous Issue of Service Bulletin

    (g) Installing an automatic shutoff system is also acceptable
for compliance with the requirements of paragraph (f) of this AD if
done before the effective date of this AD in accordance with Boeing
Alert Service Bulletin 767-28A0083 or 767-28A0084, both dated May 3,
2006; as applicable.

Revision of Airplane Flight Manual (AFM)

    (h) Concurrently with accomplishing the actions required by
paragraph (f) of this AD: Revise the Boeing 767 AFM as specified in
paragraphs (h)(1) and (h)(2) of this AD. This may be done by
inserting a copy of this AD into the AFM.
    (1) Revise Section 1, Certificate Limitations, to include the
following:

    ``Intentional dry running of a center tank fuel pump (CTR L FUEL
PUMP or CTR R FUEL PUMP message displayed on EICAS) is prohibited.
    Do not reset a tripped fuel pump or fuel pump control circuit
breaker.''

    (2) Revise Section 3.1, Normal Procedures, to include the
following:

``CENTER TANK FUEL PUMPS

    Center tank fuel pumps must not be ``ON'' unless personnel are
available in the flight deck to monitor low PRESS lights.
    For ground operations prior to engine start:
    The center tank fuel pump switches must not be positioned ON
unless the center tank contains usable fuel. With center tank fuel
pump switches ON, verify both center tank fuel pump low PRESS lights
are illuminated and EICAS CTR L FUEL PUMP and CTR R FUEL PUMP
messages are displayed.
    For ground operations after engine start and flight operations:
The center tank fuel pump switch must be selected OFF when the
respective CTR L FUEL PUMP or CTR R FUEL PUMP message displays. Both
center tank fuel pump switches must be selected OFF when either the
CTR L FUEL PUMP or CTR R FUEL PUMP message displays if the center
tank is empty. During cruise flight, both center tank pump switches
may be reselected ON whenever center tank usable fuel is indicated.

DE-FUELING AND FUEL TRANSFER

    When transferring fuel or de-fueling center or main wing tanks,
the center fuel pump low PRESS must be monitored and the fuel pump
switches positioned to ``OFF'' at the first indication of low
pressure. Prior to transferring fuel or de-fueling, conduct a lamp
test of the respective fuel pump low PRESS lights.''

    Note 2: When statements identical to those in paragraph (g) of
this AD have been included in the general revisions of the AFM, the
general revisions may be inserted into the AFM, and the copy of this
AD may be removed from the AFM.

Revision of Airworthiness Limitations

    (i) Concurrently with accomplishing the actions required by
paragraph (f) of this AD: Revise Section 9 of the Boeing 767
Maintenance Planning Data (MPD) Document D622T001-9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements
(CMRs),'' to incorporate Revision March 2006. Accomplishing the
revision in accordance with a later revision of the MPD is an
acceptable method of compliance if the revision is approved by the
Manager, Seattle Aircraft Certification Office (ACO), FAA.

Placard Installation

    (j) For Model 767-200, -300, or -300F airplanes that meet the
conditions of paragraphs (j)(1) and (j)(2) of this AD: Within 30
days after the effective date of this AD, install a placard in the
flight deck adjacent to each pilot's primary flight display, to
alert the flight crew to follow the procedures required by paragraph
(b) of AD 2001-15-08. The placard must include the following
statement:

    ``AD 2001-15-08 fuel usage restrictions required.''

Alternative placard wording may be used if approved by an
appropriate FAA Principal Operations Inspector. Alternative placard
methods and alternative methods of mixed fleet configuration control
may be used if submitted for review in accordance with the
procedures specified in paragraph (l) of this AD.
    (1) The airplane is operated in a fleet of airplanes on which
the actions specified in paragraph (f) of this AD have been done on
at least one of the fleet's airplanes.
    (2) The actions specified in paragraph (i) of AD 2001-15-08
(installation of modified center tank override and override/jettison
fuel pumps that are not subject to the unsafe condition described in
this AD) or paragraph (f) of this AD have not been done on the
airplane.

    Note 3: If the actions specified in paragraph (f) of this AD
have been done on all airplanes operated within an operator's fleet,
or if operation according to the fuel usage restrictions of AD 2001-
15-08 is maintained until automatic shutoff systems are installed on
all airplanes in an operator's fleet: No placard is necessary before
removal of the wet shutoff restrictions of AD 2001-15-08.

Terminating Action for AD 2001-15-08

    (k) For airplanes that have automatic shutoff systems installed:
Accomplishment of paragraphs (f) and (j) of this AD terminates the
requirements of paragraphs (b) and (c) of AD 2001-15-08.

Alternative Methods of Compliance (AMOCs)

    (l)(1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
