14 CFR Part 39

[Docket No. FAA-2012-0111; Directorate Identifier 2011-NM-089-AD; 
Amendment 39-17407; AD 2013-07-03]
RIN 2120-AA64


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.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

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.

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.
