Airworthiness Directives; Airbus Model A310 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) * * * was issued to require a set of 
inspection and modification tasks which addressed JAR/FAR [Joint 
Aviation Regulation/Federal Aviation Regulation] 25-571 requirements 
related to damage-tolerance and fatigue evaluation of structure. * * 
*
* * * * *

The unsafe condition is reduced structural integrity of the wings. The 
proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by February 17, 
2011.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2009-0057, dated March 13, 2009 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) original

[[Page 51]]

issue up to revision 7 was issued to require a set of inspection and 
modification tasks which addressed JAR/FAR [Joint Aviation 
Regulation/Federal Aviation Regulation] 25-571 requirements related 
to damage-tolerance and fatigue evaluation of structure.
    Following the Extended Design Service Goal activities as part of 
the Structure Task Group for the Airbus A310 program, EASA published 
AD 2007-0053, which replaced DGAC France AD F-1992-106-132R7.
    Since the issuance of AD 2007-0053R1, the thresholds and the 
intervals of Airbus Service Bulletins (SB) A310-57-2050 and A310-57-
2064 have been updated.
    Consequently, this new [EASA] AD takes over the requirements of 
paragraphs 1.15 and 1.17 of EASA AD 2007-0053R1, which has been 
revised accordingly * * * and requires the accomplishment of Airbus 
SB A310-57-2048 at revision 01.

The unsafe condition is reduced structural integrity of the wings. The 
required actions are as follows, depending on airplane configuration:
     Cold working of trellis boom drainage holes.
     Repetitive detailed or rotating probe inspections for 
cracking in the drain holes on the lower skin panel in the center wing 
box between frames 42 and 46 and corrective actions if necessary. 
Corrective actions include repairing cracking and contacting the FAA or 
EASA for repair and doing the repair.
     Repetitive eddy current inspections for cracking of the 
upper corner angle fitting and the vertical tee fitting at left and 
right frame 40, and corrective actions if necessary. Corrective actions 
include repairing, replacing the internal angle fitting and contacting 
the FAA or EASA for repair and doing the repair.

You may obtain further information by examining the MCAI in the AD 
docket.

Other Relevant Rulemaking

    We are considering issuing three other NPRMs related to this NPRM:
     Directorate Identifier 2010-NM-092-AD. That NPRM proposes 
to supersede AD 98-26-01, amendment 39-10942 (63 FR 69179, December 16, 
1998), to continue to require certain actions specified in that AD. 
However, that NPRM does not restate paragraphs (p) and (r) of AD 98-26-
01. Instead, certain requirements of paragraphs (p) and (r) of that AD 
are included in this NPRM, Directorate Identifier 2010-NM-090-AD.
     Directorate Identifiers 2010-NM-089-AD and 2010-NM-091-AD. 
Both of these NPRMs include the requirements of certain other 
paragraphs of AD 98-26-01.

Relevant Service Information

    Airbus has issued the service bulletins listed in the table that 
follows:

 2064, including Appendix 1.
----------------------------------------------------------------------------------------------------------------

    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 44 products of U.S. registry. We also estimate that 
it would take about 137 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $512,380, or $11,645 per product.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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); and
    3. 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 proposed AD and placed it in the AD docket.
