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 Airworthiness Directive (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

    On December 8, 1998, we issued AD 98-26-01, Amendment 39-10942 (63 
FR 69179, December 16, 1998). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 98-26-01, we have determined that certain 
compliance times need to be reduced in order to adequately address the 
identified unsafe condition. Therefore, certain requirements of 
paragraphs (h), (i), (j), (m), (n), and (s) of that AD are included in 
this NPRM. The European Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA Airworthiness Directive 2007-0242, dated September 4, 2007 
(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 Airworthiness Directive (AD) 1992-106-132(B) original 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 [FAA AD 98-
26-01 corresponds to DGAC AD 1992-106-132(B)R4, dated June 5, 1996].
    Following the Extended Design Service Goal activities as part of 
the Structure Task Group for the Airbus A310 program, EASA issued AD 
2007-0053 which replaced DGAC France AD F-1992-106-132R7. Since the 
issuance of that AD, the thresholds and the intervals of some Airbus 
Service Bulletins (SBs which address structure fatigue related areas 
on the wing parts), until now part of the requirements of AD 2007-
0053, have been updated.
    For the reasons stated above, this new [EASA] AD requires the 
accomplishment of the structural fatigue-related corrective actions 
in accordance with the latest revision of these SBs which have been 
reviewed in the context of the A310 Extended Service Goal 
activities. Consequently, this new AD supersedes the requirements of 
paragraphs 1.8, 1.9, 1.10, 1.13, 1.18 of EASA AD 2007-0053, which 
has been revised accordingly.

The unsafe condition is reduced structural integrity of the wings. The 
required actions are as follows, depending on airplane configuration:
     For certain Model A310-203 and A310-222 airplanes: 
Repetitive detailed inspections for cracking of the leading edge access 
panels around the bolt holes, and repair if necessary.
     For certain Model A310-203, A310-204, A310-222, A310-304, 
A310-322, A310-324, and A310-325 airplanes: Repetitive eddy current 
inspections to detect cracks in the holes around the overwing refueling 
aperture at ribs 13-14, and repair if necessary.
     For certain Model A310-203, A310-204, A310-222, A310-304, 
A310-322, A310-324, and A310-325 airplanes: Repetitive external 
detailed inspections for cracking of the top skin at ribs 13-14, 
repetitive internal detailed inspections for cracking of stringer 7 and 
stringer 8 of the overwing refuel aperture, and repair if necessary.
     For certain Model A310-203 and A310-222 airplanes: 
Repetitive detailed inspections for cracking around the bolts in the 
wing top skin upper surface of the front spar between rib 7 and rib 28, 
and repair if necessary.
     For certain Model A310-203 and A310-222 airplanes: 
Repetitive high frequency eddy current (HFEC) or X-ray inspections to 
detect cracking of the stringer runouts inboard and outboard of rib 14 
at stringers 6, 7, 8, and 9, and repair if necessary.
     For certain Model A310-203, A310-204, A310-222, A310-304, 
A310A-322, and A310-324 airplanes: Repetitive ultrasonic inspections 
for cracking in certain bolt holes where the main landing gear forward 
pick-up fitting is attached to the rear spar, and repair if necessary.
    You may obtain further information by examining the MCAI in the AD 
docket.

Other Relevant Rulemaking

    On September 5, 1990, we issued AD 90-19-07, Amendment 39-6731 (55 
FR 37455), for certain Airbus Model A310-200 series airplanes, to 
require repetitive X-ray inspections of stringers 6, 7, 8, and 9 run-
outs inboard and outboard of rib 14, and repair if necessary. 
Accomplishing an inspection in accordance with paragraph (l) of this AD 
would terminate the requirements of paragraph (a) of AD 90-19-07.
    On March 6, 1991, we issued AD 91-06-18, amendment 39-6940 (56 FR 
10796), for all Airbus Model A310-200 series airplanes, to require 
repetitive high frequency eddy current (HFEC) rototest inspections to 
detect cracks in the wing rear spar at certain bolt holes where the 
main landing gear (MLG) forward pick-up fittings are attached to the 
rear spar, and repair, if necessary. Accomplishing an inspection in 
accordance with paragraph (q) of this AD would terminate the 
requirements of AD 91-06-18, amendment 39-6940.
    We are also 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 (h), (i), (j), (m), (n), 
and (s) of AD 98-26-01. Instead, certain requirements of paragraphs 
(h), (i), (j), (m), (n), and (s) of that AD are included in this NPRM, 
Directorate Identifier 2010-NM-091-AD.
     Directorate Identifiers 2010-NM-089-AD and 2010-NM-090-AD. 
Both of these NPRMs include the requirements of certain other 
paragraphs of AD 98-26-01.

    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 97 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 $362,780, or $8,245 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.

FAA AD Differences

    Note 6:  This AD differs from the MCAI and/or service 
information as follows:
    Although the MCAI or service information allows further flight 
after cracks are found during compliance with the required action, 
paragraph (j) of this AD requires that you repair the crack(s) 
before further flight.

Other FAA AD Provisions

    (v) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. Send information to ATTN: Dan 
Rodina, Aerospace Engineer, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 
98057-3356; telephone (425) 227-2125; fax (425) 227-1149. Before 
using any approved AMOC on any airplane to which the AMOC applies, 
notify your principal maintenance inspector (PMI) or principal 
avionics inspector (PAI), as appropriate, or lacking a principal 
inspector, your local Flight Standards District Office. The AMOC 
approval letter must specifically reference this AD. AMOCs approved 
previously in accordance with AD 98-26-01, amendment 39-10942, are 
approved as AMOCs for the corresponding provisions of this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has 
approved the information collection requirements and has assigned 
OMB Control Number 2120-0056.
