Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A330-200, A330-200 Freighter, A330-300, A340-200, and
A340-300 series airplanes; and Model A340-541 airplanes and Model A340-
642 airplanes. This AD was prompted by reports of cracks in the bogie
pivot pin caused by material heating due to friction between the bogie
pivot pin and bush, leading to chrome detachment and chrome dragging on
the bogie pivot pin. This AD requires repetitive detailed inspections
for degradation of the bogie pivot pins and for any cracks and damage
of the pivot pin bushes of the main and central landing gear; a
magnetic particle inspection of the affected bogie pivot pins for
corrosion and base metal cracks; and repairing or replacing bogie pivot
pins and pivot pin bushes, if necessary. We are issuing this AD to
detect and correct cracks and damage to the main and central landing
gear, which could result in the collapse of the landing gear and
adversely affect the airplane's continued safe flight and landing.
DATES: This AD becomes effective May 15, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of May 15, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 to include an AD that would apply to the specified
products. That SNPRM was published in the Federal Register on September
7, 2012 (77 FR 55163). That SNPRM proposed to correct an unsafe
condition for the specified products. The Mandatory Continuing
Airworthiness Information (MCAI) states:
During removals of A330/340 Main Landing Gear (MLG) Bogie Beams
and A340-500/600 Center Landing Gear (CLG) Bogie Beams, cracks in
the bogie pivot pin were found.
Investigations indicated that these findings were the result of
material heating, caused by friction between bogie pivot pin and
bush, leading to chrome detachment and stress corrosion cracking.
This condition, if not detected and corrected, could lead to
collapse of the main or center landing gear, possibly resulting in
damage to the aeroplane and/or injury to occupants.
As a precautionary measure, EASA [European Aviation Safety
Agency] issued AD 2011-0040 to require a one-time [detailed]
inspection of the MLG (all types of A330 and A340 aeroplanes) and
CLG (A340-500/600 aeroplanes only) to detect degradation or cracking
of the bogie pivot pin [and to detect cracks and damage of the
bushes], as applicable to aeroplane model, and the reporting of
inspections results.
Following issuance of EASA AD 2011-0040, several operators
reported finding chrome detachment or chrome dragging on bogie pivot
pin. New cases of cracks were also reported. It has been confirmed
as well that, due to similar design, the enhanced MLG bogie pivot
pin (Airbus modification 54500) could also be affected by this
condition.
Prompted by these findings, Airbus have developed an inspection
programme consisting of repetitive inspections of the bogie pivot
pin and applicable corrective actions.
For the reasons described above, this [EASA] AD, which
supersedes EASA AD 2011-0040 and extends the applicability to all
A330 and A340 aeroplanes, requires accomplishment of repetitive
inspections of the MLG and CLG (for A340-500 and A340-600
aeroplanes) bogie pivot pins and pivot pin bushes, and corrective
actions, depending on findings.
Required actions also include, for certain airplanes, a magnetic
particle inspection of the bogie pivot pin for corrosion and base metal
cracks. The corrective actions include replacing any cracked or damaged
pivot pin bush with a new or serviceable pivot pin bush, and replacing
any corroded or cracked bogie pin with a new bogie pin. You may obtain
further information by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received.
Request To Change the Compliance Time
Delta Air Lines, Inc. (DAL) requested that the initial compliance
time in paragraph (g) of the SNPRM (77 FR 55163, September 7, 2012) be
changed from ``* * * first flight of the airplane,'' to ``* * * first
flight of the new or overhauled landing gear,'' in two locations in
that paragraph. The commenter did not provide rationale for this
request.
We disagree with DAL's request. Our compliance time coincides with
EASA AD 2012-0053, dated March 30, 2012, which specifically states,
``Accomplishment of an overhaul of the landing gear does not substitute
the accomplishment of an inspection as required by paragraph (1) of
this [EASA] AD.'' The inspections required by this final rule are not
equivalent to what is accomplished during landing gear overhaul.
However, if the inspections required by this final rule are positively
verified to have been accomplished during overhaul, the overhaul date
may be used to determine the next repetitive inspection date. We have
not changed this final rule in this regard.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the 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
SNPRM (77 FR 55163, September 7, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the SNPRM (77 FR 55163, September 7, 2012).
Costs of Compliance
We estimate that this AD will affect 29 products of U.S. registry.
We also estimate that it will take about 22 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 to the U.S. operators to be $54,230, or $1,870 per product.
In addition, we estimate that any necessary follow-on actions would
take about 6 work-hours and require parts costing $21,222, for a cost
of $21,732 per product. We have no way of determining the number of
products that may need these actions.
[[Page 21228]]
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 AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the SNPRM (77 FR 55163, September 7,
2012), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
