SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Airbus Model A318
series airplanes; A319 series airplanes; A320-211, -212, -214, -231, -
232, and -233 airplanes; and A321 series airplanes. The NPRM published
in the Federal Register on September 28, 2015 (80 FR 58226) (``the
NPRM''). The NPRM was prompted by an evaluation by the DAH indicating
that the fuselage skin repairs are subject to WFD. The NPRM proposed to
require an inspection to determine whether any fuselage external skin
(doubler) repairs have been accomplished, an inspection for cracking of
certain repaired external fuselage skin areas in the fuselage, and
repair if necessary. We are issuing this AD to detect and correct
fatigue cracking of the fuselage skin, which could result in reduced
structural integrity of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2015-0036R1, dated March 31, 2015 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition on all Airbus Model A318
series airplanes; A319 series airplanes; A320-211, -212, -214, -231, -
232, and -233 airplanes, and A321 series airplanes. The MCAI states:
During A320 family Extended Service Goal full scale fatigue
tests, it was demonstrated that the inspection thresholds defined in
the current Structural Repair Manual (SRM) for the A320 family skin
repairs are insufficient to detect possible cracks becoming after
repairs. The findings are limited to 1.2 [millimeter] (mm) fuselage
skin and cover for all cut-out external repairs. The internal
repairs are not affected.
This condition, if not detected and corrected, could affect the
structural integrity of the fuselage at the repaired skin area(s).
To address this potential unsafe condition, Airbus issued Alert
Operators Transmission (AOT) A53N007-14 to provide inspection
instructions.
For the reasons described above, EASA issued AD 2015-0036
[<a href="http://www.casa.gov.au/scripts/nc.dll?WCMS:OLDASSET::svPath=/ADFiles/over/a320/,svFileName=2015-0036.pdf">http://www.casa.gov.au/scripts/nc.dll?WCMS:OLDASSET::svPath=/ADFiles/over/a320/,svFileName=2015-0036.pdf</a>] to require a one-time
inspection of the affected areas and, depending on findings,
accomplishment of applicable repair instructions.
Since that [EASA] AD was issued, operators have questioned the
inspection threshold for A318 aeroplanes (not yet in the Airbus
AOT), which is actually identical to that for A319 aeroplanes. In
addition, an error has been detected in paragraph (1) [of the EASA
AD], since external doublers may have been installed in the affected
area by a modification that may not be recorded as repair.
Such doubler installations are also subject to the inspection
requirements of this [EASA] AD, which is therefore revised to
provide clarifications, correcting paragraph (1) [of the EASA AD]
and introducing a Note.
Required actions include an inspection to determine whether any
fuselage external skin (doubler) repairs have been accomplished, an
external ultrasonic inspection or an internal low/high frequency eddy
current inspection for cracking of certain repaired external fuselage
skin areas in the fuselage, and repair if necessary. The compliance
times vary depending on airplane configuration. The earliest compliance
time is within 25,200 flight cycles since last repair, or within 350
flight cycles after the effective date of the AD, whichever occurs
later. The latest compliance time is within 45,000 flight cycles since
last repair; within 1,500 flight cycles from the effective date of the
AD, without exceeding 49,100 flight cycles since last repair; or within
350 flight cycles since the effective date of the AD; whichever occurs
latest. You may examine the MCAI in the AD docket on the Internet at

FAA-2015-3635.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received. The following
presents the comments received on the NPRM and the FAA's response to
each comment.
Support for the NPRM
Mr. Bryant Kerr stated that the NPRM is an excellent idea, and it
is always worth improving safety on airplanes.
Request To Revise Applicability
United Airlines (UAL) requested that we revise the NPRM
applicability to apply only to airplanes having repairs that were
completed before May 1, 2015, the date of the revised service repair
manual (SRM). UAL stated that any new airplane deliveries or external
repairs accomplished after the updated SRM thresholds will presumably
have the correct thresholds contained in the maintenance/inspection
program.
We partially agree with UAL's request. We agree that airplanes with
repairs accomplished using the updated SRM will be in compliance with
certain sections of this AD, such as the timescale for the inspection,
which is a subset of the AD requirements. However, the SRM update will
not replace the remaining AD requirements, which must be applicable to
all airplanes identified in paragraph (c) of this AD. We have not
changed this AD in this regard.
Request To Exclude Inspected Airplanes
Delta Airlines (DAL) stated that since certain repairs and
modifications on its airplanes have already had their first inspection
prior to the compliance time specified in the NPRM, the NPRM
requirements should not apply. DAL also stated that if an operator's
maintenance/inspection program is more stringent than the requirements
of paragraph (m) of the proposed AD, the operator should be excluded
from the NPRM requirements.
We disagree with DAL's request. Accomplishment of the first
inspection is only part of the actions required by this AD. Paragraph
(m) of this AD requires revision of the post-repair inspection
threshold(s) in the operator's maintenance program or inspection
program. This AD includes the minimum requirements for mitigating the
identified unsafe condition. However, under the provisions of paragraph
(n)(1) of this AD, we will consider requests for approval of different
methods of compliance if sufficient data are submitted to substantiate
that the change would provide an acceptable level of safety. We have
not changed this AD in this regard.
Request To Revise Compliance Time
DAL requested a compliance time extension from 350 flight cycles to
6 months. DAL stated that depending on
[[Page 38899]]
the fleet utilization, an operator of a large, older fleet could be
required to accomplish the compliance rework within a few months,
thereby creating a significant impact on its available resources. DAL
also stated that it is possible that several airplanes will be grounded
because it may not have enough resources to comply with the 350-flight-
cycle limit.
We do not agree with DAL's request. DAL's rationale for a
compliance time extension does not provide an acceptable level of
safety. The compliance time of this AD is based on a risk assessment.
Some safety issues are more time sensitive than others. We have
considered the compliance time established by EASA, and the overall
risk to the fleet, including the severity of the identified unsafe
condition and the likelihood of the occurrence of the unsafe condition,
to determine the compliance time. However, under the provisions of
paragraph (n)(1) of this AD, operators may apply for an extension of
the compliance time by providing a satisfactory rationale explaining
why a compliance time extension provides an acceptable level of safety.
We have not changed this final rule in this regard.
Request To Clarify Requirements and Approve Certain Repair Information
Sources
DAL requested that we make a distinction that the NPRM requirements
apply only to external repair fasteners common to the 1.2-millimeter
(mm) skin. DAL also stated that we should approve category B repairs
done using the latest revision of the SRM and any repair design
approval sheet (RDAS) approved after July 1, 2014. DAL stated that the
applicable Airbus SRM repair inspection thresholds have been revised
this year to address certain inadequacies.
We do not agree with DAL's requests. Paragraph (g) of this AD
already requires an inspection to determine whether any fuselage
doubler repairs have been accomplished on affected fuselage sections
with a skin thickness of 1.2 mm. DAL did not substantiate how the
corrective actions in any RDAS for category ``B'' repairs approved
after July 1, 2014, and the latest revision of the SRMs would
adequately address the unsafe condition. However, the commenter may use
the provisions of paragraph (n)(2) of this AD for obtaining corrective
actions from a manufacturer. We have not changed this AD in this
regard.
Request To Clarify Inspection Timeframes
UAL requested clarification on how the NPRM addresses detection of
cracking in the timeframe between the inspection threshold specified in
the NPRM and Airbus Alert Operators Transmission A53N007-14, dated July
22, 2014, and the repetitive inspections specified in the SRM. UAL
stated that the compliance time has a short threshold if the repair
records are inconclusive, which is as early as 350 flight cycles from
the effective date of the AD; therefore, the initial inspection could
be accomplished much earlier than the crack detection period.
We agree to clarify the inspection timeframes. The 350-flight-cycle
compliance time is a second option to the compliance time specified in
Airbus Alert Operators Transmission A53N007-14, dated July 22, 2014.
The compliance time is based on a risk assessment that takes into
consideration the fatigue crack length propagation. We have considered
the compliance time established by EASA, and the overall risk to the
fleet, including the severity of the identified unsafe condition and
the likelihood of the occurrence of the unsafe condition. No change to
the AD is necessary in this regard.
Request To Correct Non-Destructive Testing Manual (NTM) Task Numbers
DAL stated that Airbus Alert Operators Transmission A53N007-14,
dated July 22, 2014, references incorrect formatting of NTM task
numbers. DAL stated the formatting should be ``51-10-15-270-801-A01''
and ``51-10-16-250-801-A01,'' and not ``51-10-15-270-801-A-01'' and
``51-10-16-250-801-A-01.''
We disagree with DAL's statement. NTM task numbers 51-10-15-270-
801-A-01 and 51-10-16-250-801-A-01 are correctly referenced in Airbus
Alert Operators Transmission A53N007-14, dated July 22, 2014, and in
the Airbus A318/319/320/321 Non-Destructive Testing Manual. We have not
changed this AD in this regard.
Clarification of Unsafe Condition Language
We revised the description of the precipitating event in the
SUMMARY and paragraph (e) of this AD to correspond to the wording used
in the MCAI AD.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR Part 51
Airbus has issued Alert Operators Transmission A53N007-14, dated
July 22, 2014. The service information describes procedures for an
inspection to detect cracking on repaired 1.2-millimeter fuselage skin
areas on fuselage sections 11, 12, 13, 14, 16, and 17 at external
doubler repairs. This service information is reasonably available
because the interested parties have access to it through their normal
course of business or by the means identified in the ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 940 airplanes of U.S. registry.
We also estimate that it will take about 2 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of this AD on U.S. operators to be $159,800, or $170 per product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this 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.
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.
[[Page 38900]]
Regulatory Findings
We determined that 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 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.

If, during the inspection required by paragraph (g) of this AD,
it is determined that any fuselage external skin (doubler) repair
has been accomplished on fuselage section 11, 12, 13, 14, 16, or 17:
At the applicable time specified paragraph (g)(1) or (g)(2) of this
AD, do an external ultrasonic inspection or an internal low
frequency eddy current (LFEC) inspection for cracking of all of the
repaired 1.2-millimeter (mm) fuselage skin areas, in accordance with
the instructions specified in paragraph 4.2.2, ``Inspection
Requirements,'' of Airbus AOT A53N007-14, dated July 22, 2014,
except as provided by paragraph (j) of this AD.
(j) Optional Inspection for Cracking
As an optional method of compliance to the ultrasonic inspection
or LFEC inspection required by paragraph (i) of this AD: Do a high
frequency eddy current (HFEC) inspection for cracking in the cut-out
surrounding the fastener area, at and in front (approximately 10-15
millimeters) of the fastener row, after doubler removal and before
any new extended doubler installation, using a method approved by
the Manager, International Branch, ANM-116, Transport Airplane
Directorate, FAA; or the European Aviation Safety Agency (EASA); or
