ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for all
Airbus Model A318, A319, A320, and
A321 series airplanes. This AD was
prompted by a determination that
certain special washers used in the
bearing installation of the retraction jack
anchorage fitting in the main landing
gear (MLG) were incorrectly
manufactured. This AD requires an
inspection of the left-hand (LH) and
right-hand (RH) bearing assemblies of
the MLG retraction jack anchorage
fitting to verify that the special washer
is seated correctly, and related
investigative and corrective actions if
necessary. We are issuing this AD to
detect and correct installation of
incorrectly manufactured special
washers, which could lead to a local
stress concentration resulting in
possible reduction of the fatigue life of
the jack fitting, and consequent

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. The
NPRM published in the Federal
Register on July 1, 2013 (78 FR 39190).
The NPRM proposed to correct an
unsafe condition for the specified
products.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2012–0223,
dated October 23, 2012 (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:
Airbus identified a batch of special
washers, Part Number (P/N)
D5725260120000 and P/N D5725664320000,
which were incorrectly manufactured and
delivered as spares from the supplier
PO 00000
Frm 00029
Fmt 4700
Sfmt 4700

between October 2006 and January 2010. As
a result of these manufacturing defects, the
affected washers differ geometrically from
the design specifications. The results of
further analyses on Airbus A318, A319, A320
and A321 aeroplanes demonstrate that the
affected washers could be seated incorrectly
when installed on aeroplanes, which could
affect the main landing gear (MLG) retraction
jack anchorage fitting bearing installation.
This condition, if not detected and
corrected, could lead to a local stress
concentration which may reduce the fatigue
life of the jack fitting, possibly reducing the
structural integrity of the affected MLG.
For the reasons described above, this
[EASA] AD requires a one-time detailed
visual inspection of the left-hand (LH) and
right-hand (RH) MLG retraction jack
anchorage fitting bearing assemblies to verify
that the special washer is seated correctly
and, depending on findings, the
accomplishment of applicable [related
investigative action and] corrective actions.
The related investigative action is a
detailed inspection of the jack
anchorage fitting for damage, corrosion,
cracks or other defects. Corrective
actions include replacing the special
washer with a new special washer and
repairing the jack anchorage fitting if
there are signs of damage, corrosion, or
other defects. You may examine the
MCAI in the AD docket on the Internet
at https://www.regulations.gov/
#!documentDetail;D=FAA-2013-05430003.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received. The
commenter, Jeremy Schreck, supported
the NPRM (78 FR 39190, July 1, 2013).
Conclusion
We reviewed the available data,
including the comment 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:
• Are consistent with the intent that
was proposed in the NPRM (78 FR
39190, July 1, 2013) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (78 FR 39190,
July 1, 2013).
Costs of Compliance
We estimate that this AD affects 851
airplanes of U.S. registry.
We estimate the following costs to
comply with 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.

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);

The NPRM published in the Federal Register on July 1, 2013 (78 FR
39190). The NPRM proposed to correct an unsafe condition for the
specified products.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2012-0223, dated October 23, 2012 (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:
Airbus identified a batch of special washers, Part Number (P/N)
D5725260120000 and P/N D5725664320000, which were incorrectly
manufactured and delivered as spares from the supplier between
October 2006 and January 2010. As a result of these manufacturing
defects, the affected washers differ geometrically from the design
specifications. The results of further analyses on Airbus A318,
A319, A320 and A321 aeroplanes demonstrate that the affected washers
could be seated incorrectly when installed on aeroplanes, which
could affect the main landing gear (MLG) retraction jack anchorage
fitting bearing installation.
This condition, if not detected and corrected, could lead to a
local stress concentration which may reduce the fatigue life of the
jack fitting, possibly reducing the structural integrity of the
affected MLG.
For the reasons described above, this [EASA] AD requires a one-
time detailed visual inspection of the left-hand (LH) and right-hand
(RH) MLG retraction jack anchorage fitting bearing assemblies to
verify that the special washer is seated correctly and, depending on
findings, the accomplishment of applicable [related investigative
action and] corrective actions.
The related investigative action is a detailed inspection of the jack
anchorage fitting for damage, corrosion, cracks or other defects.
Corrective actions include replacing the special washer with a new
special washer and repairing the jack anchorage fitting if there are
signs of damage, corrosion, or other defects. You may examine the MCAI
in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0543-0003.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received. The commenter, Jeremy
Schreck, supported the NPRM (78 FR 39190, July 1, 2013).
Conclusion
We reviewed the available data, including the comment 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:
Are consistent with the intent that was proposed in the
NPRM (78 FR 39190, July 1, 2013) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 39190, July 1, 2013).
Costs of Compliance
We estimate that this AD affects 851 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

We have received no definitive data that would enable us to provide
part cost estimates for the on-condition actions specified in this AD.
We have no way of determining the number of products that may need
these actions.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!docketDetail;D=FAA-2013-0543; or in person at
the Docket Operations office between 9 a.m. and 5 p.m., Monday through

installation in the main landing gear (MLG) were incorrectly
manufactured. We are issuing this AD to detect and correct
installation of incorrectly manufactured special washers, which
could lead to a local stress concentration resulting in possible
reduction of the fatigue life of the jack fitting, and consequent
reduction of the structural integrity of the affected MLG.
(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) Detailed Inspection
Within 21,300 flight cycles after August 1, 2006, or within 30
days after the effective date of this AD, whichever occurs later: Do
a detailed inspection of the left-hand (LH) and right-hand (RH)
bearing assemblies of the
[[Page 65175]]
MLG retraction jack anchorage fitting for correct installation, in
accordance with the Accomplishment Instructions of Airbus Service
Bulletin A320-57-1169, Revision 01, dated September 18, 2012, except
