14 CFR Part 39

[Docket No. FAA-2014-0620; Directorate Identifier 2013-NM-238-AD; 
Amendment 39-18102; AD 2015-03-06]
RIN 2120-AA64

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2007-22-10 for 
all Airbus Model A330-200, A330-300, A340-200, A340-300, A340-500, and 
A340-600 series airplanes. AD 2007-22-10 required repetitive 
inspections of the left-hand and right-hand wing main landing gear 
(MLG) rib 6 aft bearing lugs (forward and aft) to detect any cracks on 
the two lugs, and replacement if necessary. Since we issued AD 2007-22-
10, we have received reports of additional cracking of the MLG rib 6 
aft bearing forward lug. This new AD expands the applicability and 
reduces certain compliance times. We are issuing this AD to detect and 
correct cracking of the MLG rib 6 aft bearing lugs, which could result 
in collapse of the MLG upon landing.

DATES: This AD becomes effective March 25, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 25, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2007-22-10, Amendment 39-15246 (72 FR 61796, 
November 1, 2007; corrected November 16, 2007 (72 FR 64532)). AD 2007-
22-10 applied to all Airbus Model A330-200, A330-300, A340-200, A340-
300, A340-500, and A340-600 series airplanes. The NPRM published in the 
Federal Register on September 4, 2014 (79 FR 52585).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0271, dated November 14, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition. The MCAI states:

    During Main Landing Gear (MLG) lubrication, a crack was visually 
found in the MLG rib 6 aft bearing forward lug on one A330 in-
service aeroplane. The crack had extended through the entire 
thickness of the forward lug at approximately the 4 o'clock position 
(when looking forward). It has been determined that similar type of 
crack can develop on other aeroplane types that are listed in the 
Applicability paragraph.
    This condition, if not detected and corrected, could affect the 
structural integrity of the MLG attachment.
    To address this situation, Airbus issued inspection Service 
Bulletins (SB) A330-57-3096, A340-57-4104 and A340-57-5009 to 
instruct repetitive inspection of the gear rib lugs.
    Prompted by these findings, EASA issued Emergency AD 2006-0364-E 
to require repetitive detailed visual inspections of the Left Hand 
(LH) and Right Hand (RH) wing MLG rib 6 aft bearing lugs. Later EASA 
issued AD 2007-0247R1-E, which superseded EAD 2006-0364-E, to:

--Expand the applicability to all A330 and A340 aeroplanes, because 
the interference fit bushes cannot be considered as a terminating 
action, owing to unknown root cause; and
--Add a second parameter quoted in Flight Hours (FH) to the 
inspection interval in order to reflect the aeroplane utilization in 
service.

    EASA AD 2007-0247R1-E was republished to correct a typographical 
error.
    Since the first crack finding and issuance of the inspection SBs 
and related ADs, six further cracks have been reported.
    For the reasons described above, this [EASA] AD, which 
supersedes EASA EAD 2007-0247 R1-E and retains its requirements, is 
issued to expand the applicability to the newly certified models 
A330-223F and A330-243F and to reduce the threshold further to the 
risk assessment of recent in-service experience.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0620-0004.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The commenter, an 
anonymous individual, supported the NPRM (79 FR 52585, September 4, 
2014).

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 (79 FR 52585, September 4, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 52585, September 4, 2014).

Related Service Information Under 1 CFR Part 51

    We reviewed the following service bulletins:
     Airbus Service Bulletin A330-57-3096, Revision 5, dated 
October 17, 2013.
     Airbus Service Bulletin A340-57-4104, Revision 4, dated 
October 17, 2013.
     Airbus Service Bulletin A340-57-5009, Revision 3, dated 
October 17, 2013.
    The service information describes procedures for detailed 
inspections of the MLG rib 6 forward and aft lugs for cracking. This 
service information is reasonably available; see ADDRESSES for ways to 
access this service information.

Costs of Compliance

    We estimate that this AD affects 81 airplanes of U.S. registry.
    We 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. 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 $13,770, or $170 per product.
    We have no definitive data that would enable us to provide a cost 
estimate 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.

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.
