Airbus Model A300 B4–600 and A300
B4–600R series airplanes. This proposed
AD was prompted by reports of cracks
found in the bottom wing skin stringers
at rib 14 during full-scale fatigue testing
and in service. This proposed AD would
require modifying the profile of stringer
run-outs at rib 14 of both wings,
including a high frequency eddy current
inspection of the fastener holes for
defects and repair if necessary. We are
proposing this AD to prevent cracking
in the bottom wing skin stringers, which
could result in reduced structural
integrity of the wings.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2013–0008R1,
dated January 22, 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:
During full-scale fatigue testing, cracks
were detected in the bottom wing skin
stringers at rib 14. In addition, A300
aeroplane operators have also reported
finding cracks in the same area.
This condition, if not detected and
corrected, could impair the structural
integrity of the wings.
Additional analysis results showed that the
improved design of the stringer run-out is
necessary for aeroplanes operating beyond
the ESG 1 [extended service goal 1: 42,500
flight cycles].
For the reasons described above, this
[EASA] AD requires the removal of the
stringer end run-out plate at stringer 19 on
the bottom wing skin and the re-profiling
modification of the stringers 10, 11, 12, 17
and 19.
*
*
*
*
*
The modification also includes doing
a high frequency eddy current
inspection of the fastener holes for
defects and repair if necessary. You may
obtain further information by examining
the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Mandatory Service
Bulletin A300–57–6046, Revision 01,
dated April 18, 2011. 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
E:\FR\FM\01AUP1.SGM
01AUP1
Federal Register / Vol. 78, No. 148 / Thursday, August 1, 2013 / Proposed Rules
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This Proposed AD
and the MCAI or Service Information
Although Airbus Mandatory Service
Bulletin A300–57–6046, Revision 01,
dated April 18, 2011, specifies to
contact the manufacturer for
instructions to repair certain conditions,
this proposed AD would require
repairing those conditions using a
method approved by either the Manager,
International Branch, ANM–116,
46537
Transport Airplane Directorate, FAA; or
the EASA (or its delegated agent).
Costs of Compliance
We estimate that this proposed AD
affects 29 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS
Cost per
product
Action
Labor cost
Parts cost
Modification of the profile of stringer run-outs.
60 work-hours × $85 per hour =
$5,100.
None ......................................
We have received no definitive data
that would enable us to provide cost
estimates for any on-condition actions
specified in this proposed AD. We have
no way of determining the number of
aircraft that might need this repair.

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
VerDate Mar<15>2010
16:23 Jul 31, 2013
Jkt 229001
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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

We propose to adopt a new
airworthiness directive (AD) for all The
Boeing Company Model 727 airplanes.
This proposed AD was prompted by
reports indicating that a standard fuel
tank access door was located where an
impact-resistant access door was
required, and stencils were missing
from some impact-resistant access
doors. This proposed AD would require
an inspection of the left- and right-hand
wing fuel tank access doors to
determine that impact-resistant access
doors are installed in the correct
locations, and to replace any door with
an impact-resistant access door if
necessary. This proposed AD also
would require an inspection for stencils
and index markers on impact-resistant
access doors, and application of new
stencils or index markers if necessary.
This proposed AD would also require
revising the maintenance program to
incorporate changes to the airworthiness
limitations section. We are proposing
this AD to prevent foreign object
penetration of the fuel tank, which
could cause a fuel leak near an ignition
source (e.g., hot brakes), consequently
leading to a fuel-fed fire.
DATES: We must receive comments on
this proposed AD by September 16,
2013.
SUMMARY:
You may send comments,

We received reports of a standard fuel
tank access door located where an
impact-resistant access door is required,
and stencils missing from some spare
impact-resistant access doors. This
condition, if not corrected, could result
in foreign object penetration of the fuel
tank, which could cause a fuel leak near
an ignition source (e.g., hot brakes),
consequently leading to a fuel-fed fire.

You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletin A300-57-6046, Revision
01, dated April 18, 2011. 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
[[Page 46537]]
condition exists and is likely to exist or develop on other products of
the same type design.
Differences Between This Proposed AD and the MCAI or Service
Information
Although Airbus Mandatory Service Bulletin A300-57-6046, Revision
01, dated April 18, 2011, specifies to contact the manufacturer for
instructions to repair certain conditions, this proposed AD would
require repairing those conditions using a method approved by either
the Manager, International Branch, ANM-116, Transport Airplane
Directorate, FAA; or the EASA (or its delegated agent).
Costs of Compliance
We estimate that this proposed AD affects 29 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Modification of the profile of 60 work-hours x $85 None............... $5,100 $147,900
stringer run-outs. per hour = $5,100.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for any on-condition actions specified in this proposed
AD. We have no way of determining the number of aircraft that might
need this repair.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
Airbus: Docket No. FAA-2013-0668; Directorate Identifier 2013-NM-
017-AD.
(a) Comments Due Date
We must receive comments by September 16, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, and
B4-622 airplanes; and Airbus Model A300 B4-605R and B4-622R
airplanes; certificated in any category, except airplanes on which
Airbus Modification 10324 or 10325 has been embodied in production.
(d) Subject
Air Transport Association (ATA) of America Code 57, Wings.
(e) Reason
This AD was prompted by reports of cracks found in the bottom
wing skin stringers at rib 14 during full-scale fatigue testing and
in service. We are issuing this AD to prevent cracking in the bottom
wing skin stringers, which could result in reduced structural
integrity of the wings.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Modification of Rib 14
Before the accumulation of 42,500 total flight cycles, or within
2,000 flight cycles after the effective date of this AD, whichever
occurs later, modify the profile of stringer run-outs at rib 14 of
both wings, including a high frequency eddy current inspection of
the fastener holes for defects and all applicable repairs, in
accordance with the Accomplishment Instructions of Airbus Mandatory
Service Bulletin A300-57-6046, Revision 01, dated April 18, 2011,
except as required by paragraph (h) of this AD.
(h) Exception to the Service Information
