Airworthiness Directives; Airbus Airplanes
Publication summary
We are adopting a new airworthiness directive (AD) for all Airbus Model A319-131, -132, and -133 airplanes; Model A320-232 and - 233 airplanes; and Model A321-131, -231, and -232 airplanes. This AD was prompted by reports of forward engine mount attachment pins that were manufactured from discrepant raw material. This AD requires identification and replacement of affected forward engine mount attachment pins. We are issuing this AD to prevent failure of a forward engine mount attachment pin, possible loss of an engine in-flight, and consequent reduced controllability of the airplane.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A319-131, -132, and -133 airplanes; Model A320-232 and -
233 airplanes; and Model A321-131, -231, and -232 airplanes. This AD
was prompted by reports of forward engine mount attachment pins that
were manufactured from discrepant raw material. This AD requires
identification and replacement of affected forward engine mount
attachment pins. We are issuing this AD to prevent failure of a forward
engine mount attachment pin, possible loss of an engine in-flight, and
consequent reduced controllability of the airplane.
DATES: This AD becomes effective April 22, 2016.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 22,
2016.

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 A319-131,
-132, and -133 airplanes; Model A320-232 and -233 airplanes; and Model
A321-131, -231, and -232 airplanes. The NPRM published in the Federal
Register on July 30, 2015 (80 FR 45462) (``the NPRM'').
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2015-0004, dated January 13, 2015 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Airbus Model
A319-131, -132, and -133 airplanes; Model A320-232 and -233 airplanes;
and Model A321-131, -231, and -232 airplanes. The MCAI states:
A number of forward engine mount pins, Part Number (P/N) 740-
2022-501, intended for IAE V2500 series engines, have been reported
as non-compliant with the current certification requirements, due to
a quality issue during manufacturing of the raw material. It was
also determined that a batch of 88 affected pins are installed on
in-service aeroplanes fitted with forward engine mount P/N 745-2010-
503 and the serial numbers (s/n) of the affected pins and the
[manufacturer serial number] MSN of the related aeroplanes have been
identified.
This condition, if not corrected, could lead to forward engine
mount pin failure, possibly resulting in in-flight loss of an engine
and consequent reduced control of the aeroplane.
For the reasons described above, this [EASA] AD requires
identification of the affected forward engine mount pins and removal
from service [replacement] of those pins.
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-
2963.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.
Request To Clarify Which Attachment Pin Part Numbers May Be Installed
United Airlines (UAL) requested that paragraph (h) of the proposed
AD be re-written to clarify which attachment pin part numbers can be
used as replacement parts.
We partially agree with the commenter's request. We agree to
provide clarification but we do not agree to revise paragraph (h) of
this AD. Paragraph (h) of this AD states to replace with a serviceable
part having a part number other than part number (P/N) 740-2022-501,
and having a serial number that is not identified in figure 1 to
paragraphs (h) and (j) of this AD. In other words, the replacement part
cannot have a combination of P/N 740-2022-501 and any serial number
that is
[[Page 14690]]
included in figure 1 to paragraphs (h) and (j) of this AD. We have not
changed this AD in this regard.
Request To Clarify Which Airplanes Are Not Affected by the Requirements
Proposed in the NPRM
JetBlue requested clarification of the intent of paragraph (i) of
the proposed AD. JetBlue asserted that the way this paragraph is
written it contradicts the requirements in EASA AD 2015-0004, dated
January 13, 2015, and the intent of the inspection in paragraph (h) of
the proposed AD.
We agree with the commenter's request to clarify the intent of
paragraph (i) of this AD. Airplanes with manufacturer serial numbers
not identified in figure 2 to paragraph (i) of this AD that have not
had an engine replaced after March 1, 2011, are not required to do the
actions mandated by paragraphs (g) and (h) of this AD, which
corresponds to paragraph (2) of the MCAI AD. In paragraph (i) of the
proposed AD we inadvertently specified ``airplanes with manufacturer
serial numbers identified in figure 2 to paragraph (i) of this AD.'' We
have changed paragraph (i) of this AD to specify ``airplanes with
manufacturer serial numbers not identified in figure 2 to paragraph (i)
of this AD.''
Request To Extend the Compliance Time
UAL requested that the compliance times in paragraph (g) of the
proposed AD be extended. UAL stated that this would keep costs down and
``make engine removal the most likely time the inspection would
occur.'' UAL also asserted that the safety concern is overstated based
on information in the Goodrich Aerostructures service information. The
``Background'' paragraph of the Goodrich Aerostructures service
information states that ``a minor metallurgical discontinuity'' was
found on some forward engine mount crossbeam to main beam attach pins
(P/N 740-2022-501). UAL stated that a minor metallurgical issue should
not drive a significant safety concern.
We do not agree with the commenter's request to extend the
compliance time. Even a ``minor metallurgical discontinuity'' can
result in a safety concern. Forward engine mount attachment pins that
were manufactured from discrepant raw material can lead to the failure
of a forward engine mount attachment pin; this condition could result
in possible loss of an engine in-flight and consequent reduced
controllability of the airplane.
After considering all of the available information, we have
determined that the compliance time, as proposed, represents an
appropriate interval of time in which the required actions can be
performed in a timely manner with the affected fleet, while still
maintaining an adequate level of safety. In developing an appropriate
compliance time, we considered the safety implications, parts
availability, and normal maintenance schedules for timely
accomplishment of the replacement. However, under the provisions of
paragraph (m)(1) of this AD, we may approve requests for adjustments to
the compliance time if data are submitted to substantiate that such an
adjustment would provide an acceptable level of safety. We have not
changed this AD in this regard.
Request To Revise the Estimated Costs of Compliance
UAL requested that the estimated costs of compliance in the NPRM be
increased from $156,740 to $313,480. UAL also requested that the costs
for opening and closing the reversers be mentioned as costs that cannot
be calculated. Furthermore, UAL stated that based on the proposed
compliance times in paragraph (g) of the proposed AD and the size of
the UAL fleet, the proposed requirements would have to be scheduled
independently from its maintenance schedule.
We agree with the commenter's request to increase the estimated
costs for compliance with the requirements of this AD. We note that
these are only estimated costs and may vary based on an airplane's
configuration. We also acknowledge that the costs for opening and
closing the reversers are not known and are not included in the ``Costs
of Compliance'' paragraph of this AD. However, as specified in the
service information, the inspection takes approximately 4 work-hours,
with an estimated cost of $313,480 for U.S. operators. We have changed
the ``Costs of Compliance'' paragraph of this AD accordingly.
Request To Refer to Current Service Information
JetBlue Airways (JetBlue) requested that the NPRM be revised to
refer to Airbus Service Bulletin A320-71-1064, Revision 01, dated April
1, 2015; and Goodrich Aerostructures Service Bulletin V2500-NAC-71-
0323, Revision 01, dated January 28, 2015. JetBlue noted that the
service information for both Airbus and Goodrich Aerostructures had
been revised since the NPRM was published.
We agree with the commenter's request and have revised the
``Related Service Information under 1 CFR part 51'' section and
paragraphs (g) and (h) of this AD to refer to Airbus Service Bulletin
A320-71-1064, Revision 01, dated April 1, 2015; and Goodrich
Aerostructures Service Bulletin V2500-NAC-71-0323, Revision 01, dated
January 28, 2015. We have also added new paragraph (l) to this AD to
give credit for actions done using Airbus Service Bulletin A320-71-
1064, dated November 5, 2014; and Goodrich Aerostructures Service
Bulletin V2500-NAC-71-0323, dated September 18, 2014. We redesignated
subsequent paragraphs accordingly.
Request To Allow Use of Airbus or Goodrich Aerostructures Service
Information To Accomplish Required Actions
JetBlue requested that paragraph (g) of the proposed AD be revised
to allow operators to use either the Airbus service information or the
Goodrich Aerostructures service information to do the actions required
by that paragraph. JetBlue stated that if the engine is being inspected
at the shop, the actions in the Airbus service information would not be
accomplished because the Airbus service information addresses
inspections of the wing. JetBlue also stated this revision would
correspond with the requirements in corresponding EASA AD 2015-0004,
dated January 13, 2015.
We do not agree with the commenter's request to allow operators to
have the option of doing the actions required by paragraph (g) of this
AD in accordance with either the Accomplishment Instructions of the
Airbus service information or the Goodrich Aerostructures service
information. The Airbus service information includes steps that are
considered ``required for compliance'' (RC) and those steps are not
included in the Goodrich Aerostructures service information. In
addition, Goodrich Aerostructures Service Bulletin V2500-NAC-71-0323,
Revision 01, dated January 28, 2015, does not distinguish between
``RC'' and non-``RC'' steps and refers to the Airbus service bulletin
for incorporation of several steps. Therefore, regardless of whether
the AD requirements are accomplished ``on wing'' or ``in shop,''
operators must use a combination of Airbus and Goodrich Aerostructures
service information for accomplishing the AD requirements. We have not
changed this AD regarding this issue.
[[Page 14691]]
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and 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 Service Bulletin A320-71-1064, Revision 01, dated
April 1, 2015; and Goodrich Aerostructures has issued Service Bulletin
V2500-NAC-71-0323, Revision 01, dated January 28, 2015. The service
information describes procedures for an inspection to determine the
serial number of the attachment pins for the forward engine mount
crossbeam to main beam for each engine, and replacement of affected
pins. 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 922 airplanes of U.S. registry.
We also estimate that it will take about 4 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $0 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $313,480, or $340 per product.
In addition, we estimate that any necessary follow-on actions will
take about 4 work-hours and require parts costing $1,724, for a cost of
$2,064 per attachment pin replacement. We have no way of determining
the number of aircraft that might need this action.
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 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.
