SUPPLEMENTARY INFORMATION:

Background

    Under 49 U.S.C. 31136(e) and 31315, FMCSA may grant an exemption
from the Federal Motor Carrier Safety Regulations for a 2-year period
if it finds ``such exemption would likely achieve a level of safety
that is equivalent to or greater than the level that would be achieved
absent such exemption.'' FMCSA can renew exemptions at the end of each
2-year period. The 25 individuals listed in this notice have each
requested such an exemption from the vision requirement in 49 CFR
391.41(b)(10), which applies to drivers of CMVs in interstate commerce.
Accordingly, the Agency will evaluate the qualifications of each
applicant to determine whether granting an exemption will achieve the
required level of safety mandated by statute.

RIN 2120-AA64

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-07-
10, for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300)
airplanes. AD 2011-07-10 currently requires revising the Airworthiness
Limitations section of the Instructions for Continued Airworthiness;
doing detailed visual inspections; removing discrepant material;
cleaning the surfaces of the valves, the plug of the sensing port, and
the cabin pressure-sensing port plug; securing the insulation;
installing a new safety valve,

and replacing certain cabin pressure-sensing port plugs. Since we
issued AD 2011-07-10, we have received reports of in-flight loss of
cabin pressurization that was attributed to partial blockage of a
safety valve cabin pressure-sensing port in conjunction with a failed
safety valve manometric capsule. This proposed AD would retain all
requirements of AD 2011-07-10. This proposed AD would also require a
detailed visual inspection of both safety valves and the surrounding
area for foreign material, room temperature vulcanizing (RTV) silicone,
contamination, foam on the bulkhead structure, tape or insulation, and
loose material; and corrective actions if necessary. We are proposing
this AD to detect and correct blockage of a safety valve cabin
pressure-sensing port, which could result in loss of cabin pressure.

DATES: We must receive comments on this proposed AD by June 1, 2015.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    On March 21, 2011, we issued AD 2011-07-10, Amendment 39-16647 (76
FR 17758, March 31, 2011). AD 2011-07-10 requires actions intended to
address an unsafe condition on certain Bombardier, Inc. Model BD-100-
1A10 (Challenger 300) airplanes. AD 2011-07-10 superseded AD 2010-10-
18, Amendment 39 16297 (75 FR 27406, May 17, 2010).
    Since we issued AD 2011-07-10, Amendment 39-16647 (76 FR 17758,
March 31, 2011), we have received reports of in-flight loss of cabin
pressurization that were attributed to partial blockage of a safety
valve cabin pressure-sensing port in conjunction with a failed safety
valve manometric capsule.
    Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2010-06R1, dated August 8, 2013 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:

    Investigation of a high altitude loss of cabin pressurization on
a BD-100-1A10 aeroplane determined that it was caused by a partial
blockage of a safety valve cabin pressure-sensing port, in
conjunction with a dormant failure/leakage of the safety valve
manometric capsule. The blockage, caused by accumulation of lint/
dust on the grid of the port plug, did not allow sufficient airflow
through the cabin pressure-sensing port to compensate for the rate
of leakage from the manometric capsule, resulting in the opening of
the safety valve. It was also determined that failure of the
manometric capsule alone would not result in the opening of the
safety valve.
    The original issue of this [Canadian] AD mandated a revision of
the maintenance schedule, the cleaning of the safety valves, the
removal of material from the area surrounding the safety valves and
the modification of the safety valves with a gridless cabin
pressure-sensing port plug.
    Since the original issue of this [Canadian] AD, there have been
two additional reported events of in-flight loss of cabin
pressurization that were attributed to partial blockage of a safety
valve cabin pressure-sensing port in conjunction with a failed
safety valve manometric capsule.
    Bombardier Aerospace has determined that aeroplanes with a
particular interior installation require improved instructions to
clean the safety valves and their surrounding area. In addition,
Aircraft Maintenance Manual tasks have been updated to ensure that
inspection of the safety valves and their surrounding is carried out
after any maintenance action.
    Revision 1 of this [Canadian] AD is issued to mandate inspection
and cleaning of the safety valves and their surrounding area on the
affected aeroplanes.

    Corrective actions include removing foreign material, cleaning
surfaces of the safety valve and bulkhead, installing a new safety
valve, removing loose tape, and trimming insulation. You may examine
the MCAI in the AD docket on the Internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2015-0827.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 100-25-21, Revision 02,
dated July 25, 2013. The service information describes procedures for a
detailed visual inspection of both safety valves and the surrounding
area for foreign material, RTV silicone, contamination, foam on the
bulkhead structure, tape or insulation, and loose material, and
applicable corrective actions. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI. This service information is reasonably available; see
ADDRESSES for ways to access this service information.

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.
    This AD requires revisions to certain operator maintenance
documents to include new actions (e.g., inspections). Compliance with
these actions is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas addressed
by this AD, the operator may not be able to accomplish the actions
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 (n)(1) of this AD. The request
should include a description of changes to the required inspections
that will ensure the continued operational safety of the airplane.

Costs of Compliance

    We estimate that this proposed AD affects 67 airplanes of U.S.
registry.
    The actions required by AD 2011-07-10, Amendment 39-16647 (76 FR
17758, March 31, 2011), and retained in this proposed AD take about 10
work-hours per product, at an average labor rate of $85 per work-hour.
Required parts cost $0 per product. Based on these figures, the
estimated cost of the actions that were required by AD 2011-07-10 is
$850 per product.
    We also estimate that it would take about 4 work-hours per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this proposed AD on U.S. operators to be $22,780, or $340
per product.
    According to the manufacturer, all of the costs of this proposed AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.

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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

List of Subjects in 14 CFR Part 39

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 747 airplanes. This AD was prompted by reports of
fractured latch pins found in service; investigation revealed that the
cracking and subsequent fracture were initiated by fatigue and
propagated by a combination of fatigue and stress corrosion. This AD
requires repetitive general visual inspections for broken or missing
latch pins of the lower sills of the forward and aft lower lobe cargo
doors; repetitive detailed inspections for cracking of the latch pins;
and corrective actions if necessary. We are issuing this AD to detect
and correct fractured or broken latch pins, which could result in a
forward or aft lower lobe cargo door opening and detaching during
flight, and consequent rapid decompression of the airplane.

DATES: This AD is effective May 15, 2012.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of May 15, 2012.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on September 1, 2011
(76 FR 54405). That NPRM proposed to require repetitive general visual
inspections for broken or missing latch pins of the lower sills of the
forward and aft lower lobe cargo doors; repetitive detailed inspections
for cracking of the latch pins; and corrective actions if necessary.

Comments

    We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and the FAA's response to each comment.

Request to Withdraw the NPRM (76 FR 54405, September 1, 2011)

    United Parcel Service (UPS) asked that we withdraw the NPRM (76 FR
54405, September 1, 2011). UPS stated that there is a lack of
justification for issuing the NPRM and added that it is being issued
based on a report of a fatigue crack in the 17-4PH material latch pins
of the lower cargo door, and the assumption that adjacent latch pins
could also be affected. UPS noted that the latching structures of the
lower forward and aft cargo door each include eight latch pins; those
latch pins are part of a fail-safe design, which should preclude
critical failure with the failure of one element. UPS added that the
Model 747-400 maintenance planning document includes a detailed
inspection of the latch mechanism of the lower cargo door, which
includes the latch pins, at 2 year or 2,000 flight cycle intervals,
whichever occurs first. UPS noted that the NPRM would require
repetitive inspections at 1,600-flight-cycle intervals--a modest
increase in frequency over the existing maintenance program--which has
already been proven successful at detecting damage to adjacent latch
pins. UPS concluded that, based on the extensive fleet history of the
latch pins of these lower cargo doors, with no reports of adjacent pin
failures, the existing maintenance program inspections of the latch
pins are adequate.
    We do not agree with the commenter's request to withdraw the NPRM
(76 FR 54405, September 1, 2011). Although the commenter has not
experienced pin failure in service, the manufacturer has found pin
fatigue failure on another airplane of the same type design. Therefore,
we find we must issue this AD to address the identified unsafe
condition on the entire fleet.
    The inspections identified in the maintenance planning document are
general visual inspections of the entire door. The inspections required
by this final rule include detailed inspections of the latch pins
themselves. These detailed inspections are the result of the pin
fracturing in service. The fractured pin was the number eight latch pin
on the lower sill of the aft lower lobe cargo door; investigation by
the manufacturer revealed that the crack initiated due to fatigue, and
propagated by a combination of fatigue and stress corrosion. If the
latch pins on the lower sill are not regularly inspected, and broken
latch pins are not replaced, the forward and/or aft cargo door could
open during service, resulting in loss of the cargo door, rapid
decompression, and significant damage to the airplane. No change to the
AD is necessary in this regard.

Request To Clarify Language in Relevant Service Information Section

    Boeing asked that the description specified in the ``Relevant
Service Information'' section of the NPRM (76 FR 54405, September 1,
2011) be changed as follows: ``The service bulletin describes
procedures for repetitive detail inspections of latch pins for broken
or missing latch pins of the lower sills of the forward and aft lower
lobe cargo doors; repetitive detailed inspections of the replaced latch
pins for cracked, broken or missing latch pins; and corrective actions
if necessary.'' Boeing stated that Boeing Alert Service Bulletin 747-
53A2835, dated October 28, 2010, necessitates that a detailed
inspection be done on all pins (including previously replaced pins).
Boeing added that the detailed inspection is for cracks, and the
general visual inspection is to look for the broken and missing pins.
Boeing notes that paragraph (g) of the NPRM provides the correct
description of the inspections specified in the service bulletin.
    We acknowledge the commenter's concern and agree that the language
could be clarified somewhat; however, since that section of the
preamble does not reappear in the final rule, no change to this AD is
necessary in this regard.

Request To Include Revision 1 of the Referenced Service Bulletin

    Boeing also asked that Boeing Alert Service Bulletin 747-53A2835,
Revision 1, dated December 8, 2011, be included in the NPRM (76 FR
54405, September 1, 2011) for accomplishing certain actions. Boeing
Alert Service Bulletin 747-53A2835, dated October 28, 2010, was
referred to as the appropriate source of service information for
accomplishing the actions specified in the NPRM. Boeing added that
Boeing Alert Service Bulletin 747-53A2835, Revision 1, dated December
8, 2011, is scheduled for FAA-approval, and includes a latch pin
modification and post-modification inspection to address the safety
issue.
    We have reviewed Boeing Alert Service Bulletin 747-53A2835,
Revision 1, dated December 8, 2011, and agree to include it in this
final rule as an additional source of service information. Boeing Alert
Service Bulletin 747-53A2835, Revision 1, dated December 8, 2011,
reduces an existing compliance time, adds a latch pin modification, and
repetitive post-modification inspections. We are including the actions
in Boeing Alert Service Bulletin 747-53A2835, Revision 1, dated
December 8, 2011, as optional in order to avoid delaying issuance of
the AD. We have revised paragraph (g) of this AD accordingly. We are
currently considering additional rulemaking to require the modification
and post-modification inspections.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously--and minor editorial
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the
NPRM (76 FR 54405, September 1, 2011) for correcting the unsafe
condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 54405, September 1, 2011).
    We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 228 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                     Estimated Costs

                                        hour = $255 per                         cycle.
                                        inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements/
modifications that would be required based on the results of the
required inspection. We have no way of determining the number of
aircraft that might need these actions:

                                               On-Condition Costs

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

    This AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
    (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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

DEPARTMENT OF TRANSPORTATION

Federal Railroad Administration

[Docket Number FRA-2006-25837]

Petition for Waiver of Compliance

    Under part 211 of Title 49 Code of Federal Regulations (CFR), this
document provides the public notice that on July 27, 2017, the
Charlotte Area Transit System (CATS) petitioned the Federal Railroad
Administration (FRA) for a waiver of compliance from certain provisions
of the Federal railroad safety regulations contained at Title 49 CFR
part 219, Control of Alcohol and Drug Use. FRA assigned the petition
docket number FRA-2006-25837.
    CATS has provided rail fixed guideway public transit service in the
Charlotte, North Carolina metropolitan area since 2007 with its
original 9.6-mile Blue Line system that operates from South Charlotte
to Center City Charlotte. This portion features a shared corridor with
Norfolk Southern Railway (NS), including separation of track centers by
40 feet or more and limited connections with NS at two shared highway-
rail grade crossings at East Hebron Street and Sweden Road. CATS and NS
signal and train control employees maintain their own respective
crossing equipment. CATS is currently constructing a 9.3-mile extension
of this Blue Line (LYNX BLE) which will provide service from Center
City Charlotte to a terminus on the University of North Carolina campus
with revenue service expected to begin by March 31, 2018. This
extension will again share a corridor with NS, including a 75-foot
track center separation and one limited connection with NS at a shared
highway-rail grade crossing at 16th Street. CATS employees will
continue to maintain crossing equipment on the CATS side of the
corridor only, with NS employees maintaining the equipment on the NS
side.
    CATS seeks relief from 49 CFR part 219 because it is already in
compliance with Federal Transit Administration drug and alcohol
regulations at 49 CFR part 655. CATS asserts this compliance provides
an equivalent level of safety consistent with FRA's alcohol and drug
regulations in part 219. CATS states that such a waiver will not result
in any reduction in safety at the highway rail grade crossings it
shares with NS and will preserve consistency throughout the CATS system
for already-existing alcohol and drug policies.
    A copy of the petition, as well as any written communications
concerning the petition, is available for review online at
www.regulations.gov and in person at the U.S. Department of
Transportation's (DOT) Docket Operations Facility, 1200 New Jersey
Avenue SE., W12-140, Washington, DC 20590. The Docket Operations
Facility is open from 9 a.m. to 5 p.m., Monday through Friday, except
Federal Holidays.
    Interested parties are invited to participate in these proceedings
by submitting written views, data, or comments. FRA does not anticipate
scheduling a public hearing in connection with these proceedings since
the facts do not appear to warrant a hearing. If any interested parties
desire an opportunity for oral comment and a public hearing, they
should notify FRA, in writing, before the end of the comment period and
specify the basis for their request.
    All communications concerning these proceedings should identify the
appropriate docket number and may be submitted by any of the following
