Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to certain Airbus Model A310 series airplanes. The 
existing AD currently requires repetitive inspections for fatigue 
cracking of the area around the fasteners of the landing plate of the 
aileron access doors of the bottom skin panel of the wings, and related 
corrective action. The existing AD provides for an optional terminating 
action, which ends the repetitive inspections. Since we issued that AD, 
a reassessment of the previous fatigue threshold and inspection 
interval resulted in a determination that reduced inspection thresholds 
and intervals for accomplishment of the tasks are necessary. This 
proposed AD would reduce the initial inspection compliance time and 
intervals and provide additional terminating action options. We are 
proposing this AD to detect and correct fatigue cracking of the area 
around the fasteners of the landing plate of the aileron access doors 
and the bottom skin panel of the wings, which could result in reduced 
structural integrity of the wings.

Discussion

    On July 9, 2004, we issued AD 2004-15-07, Amendment 39-13741 (69 FR 
44592, July 27, 2004). That AD required actions intended to address an 
unsafe condition on Airbus Model A310 series airplanes.
    Since we issued AD 2004-15-07, Amendment 39-13741 (69 FR 44592, 
July 27, 2004), the manufacturer has done a reassessment of the 
previous fatigue threshold and inspection interval resulting in a 
recommendation of reduced inspection thresholds and intervals for 
accomplishment of the tasks. The European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2011-0125, 
dated June 30, 2011 (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 issued AD 2003-242(B) [which corresponds to FAA AD 2004-15-
07, Amendment 39-13741 (69 FR 44592, July 27, 2004)] to require an 
inspection programme for aeroplanes with pre- and post-Airbus 
modification 05106 configurations (Airbus SB A310-57-2004) in order 
to detect any crack located on the trailing edge of the wing bottom 
skin No.2 panel of the all-speed-aileron servo control bay. A crack 
at this location, if not detected and corrected, would propagate 
towards the wing rear spar and ultimately into the wing fuel tank 
area. Undetected cracks would affect the structural integrity of the 
[left hand] LH and/or [right hand] RH wing.
    Since issuance of DGAC France AD 2003-242(B), a reassessment of 
the previous fatigue threshold and inspection interval has been 
completed. As a result of the reassessment, the inspection 
thresholds and intervals for accomplishment of the tasks as defined 
in Airbus SB A310-57-2082 have been adjusted and reduced. Airbus SB 
A310-57-2082 Revision 03 has been published, in which the compliance 
time periods for these inspection thresholds and intervals have been 
amended.
    For the reasons stated above, this [EASA] AD retains the 
requirements of the DGAC France AD 2003-242(B), which is superseded, 
and requires implementation of the amended inspection programme.

Corrective action includes doing a permanent repair (installing a 
repair plate and new landing plates), a temporary repair (crack-stop 
drilling and application of a protective coating) followed by 
repetitive inspections until a permanent repair is done, and a repair 
approved by the FAA or EASA (or its delegated agent). This proposed AD 
also adds optional permanent repairs.
    The initial inspection compliance times are dependent on the 
configuration (modification status, repair status, and crack length), 
and type of use (short range, long range, and normal). For airplanes 
without temporary repairs, the initial inspection compliance time 
ranges between 2,000 total flight cycles or 10,200 total flight hours, 
whichever occurs first; and 12,000 total flight cycles or 24,000 total 
flight hours, whichever occurs first. If the total flight cycles or 
total flight hours compliance time has been exceeded, the initial 
inspection compliance time (grace period) ranges between 200 flight 
cycles or 1,000 flight hours, to within 1,000 flight cycles or 2,800 
flight hours, whichever occurs first.
    For airplanes with temporary repairs, the initial inspection 
compliance time is dependant on crack length and ranges between 7 
flight cycles or 35 flight hours, whichever occurs first, since the 
repair; to within 100 flight cycles or 200 flight hours, whichever 
occurs first, since the repair.
    For airplanes with a temporary repair, the compliance time for 
completing the permanent repair ranges between 35 flight cycles or 175 
flight hours, whichever occurs first, after completing the temporary 
repair; to within 500 flight cycles or 1,000 flight hours, whichever 
occurs first, after completing the temporary repair.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued the following service information.
     Airbus Service Bulletin A310-57-2081, Revision 03, dated 
October 13, 2010.
     Airbus Mandatory Service Bulletin A310-57-2082, Revision 
03, dated November 15, 2010.
     Airbus Repair Instruction R573-49237, Repair To Crack In 
Trailing Edge Bottom Skin Panel No 2 Both Wings, Revision D, dated July 
16, 2003.
     Airbus Repair Instruction R573-49243, Repair to cracks in 
all speed aileron access door landing plates, both wings, Revision C, 
dated July 16, 2003.
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

    Airbus Mandatory Service Bulletin A310-57-2082, Revision 03, dated 
November 15, 2010; and Airbus Service Bulletin A310-57-2081, Revision 
03, dated October 13, 2010; specify to contact the manufacturer for 
instructions on how to repair certain conditions, but this proposed AD 
would require repairing those conditions using a method approved by the 
FAA or the EASA (or its delegated agent).

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 58 products of U.S. registry.
    The actions that are required by AD 2004-15-07, Amendment 39-13741 
(69 FR 44592, July 27, 2004), and retained in this proposed AD take 
about 2 work-hours per product, at an average labor rate of $85 per 
work hour. Based on these figures, the estimated cost of the currently 
required actions is $170 per product.
    We estimate that it would take about 4 work-hours per product to 
comply with the new 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 $19,720, or $340 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD. 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 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 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 proposed AD and placed it in the AD docket.

    This paragraph restates the requirements of paragraph (c) of AD 
2004-15-07, Amendment 39-13741 (69 FR 44592, July 27, 2004). If any 
cracking is found during any inspection required by paragraph (g) or 
(h) of this AD: Before further flight, do the actions required by 
either paragraph (i)(1) or (i)(2) of this AD.
    (1) Do a permanent repair of the area by doing the applicable 
corrective actions per the Accomplishment Instructions of Airbus 
Service Bulletin A310-57-2082, dated June 11, 2002. Accomplishment 
of the permanent repair terminates the repetitive inspections 
required by this AD for the repaired area only.
    (2) Do the terminating action specified in paragraph (j) of this 
AD.

(j) Retained Optional Terminating Action, With New Service Information 
and Options

    This paragraph restates the retained optional terminating action 
information specified in paragraph (d) of AD 2004-15-07, Amendment 
39-13741 (69 FR 44592, July 27, 2004), with new service information 
and new options. Modification of the landing plate of the aileron 
access doors of the wing bottom skin panel No. 2 of the left and 
right wings by doing all the actions, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A310-57-2081, 
dated June 11, 2002, or Airbus Service Bulletin A310-57-2081, 
Revision 03, dated October 13, 2010; or by doing the repair in 
accordance with Airbus Repair Instruction R573-49243, Revision C, 
dated July 16, 2003, or Airbus Repair Instruction R573-49237, 
Revision D, dated July 16, 2003; terminates the requirements of this 
AD. Where Airbus Service Bulletin A310-57-2081, dated June 11, 2002; 
and Airbus Service Bulletin A310-57-2081, Revision 03, dated October 
13, 2010; specify contacting the manufacturer for disposition of 
certain repair conditions that might be associated with the 
modification procedure, this AD requires that the repair be done in 
accordance with a method approved by either the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
the Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) (or 
its delegated agent); or the European Aviation Safety Agency (EASA)

(k) New Inspections, Related Investigative Actions, and Corrective 
Actions

    Except as specified in paragraph (m)(1) of this AD, at the 
applicable time specified in Paragraph 1.E., ``Compliance,'' of 
Airbus Mandatory Service Bulletin A310-57-2082, Revision 03, dated 
November 15, 2010: Do a high frequency eddy current (HFEC) 
inspection to detect cracking of the area around the fasteners of 
the landing plate of the wing bottom skin panel No. 2 of the left 
and right wings; and do all applicable corrective actions; in 
accordance with the Accomplishment Instructions of Airbus Mandatory 
Service Bulletin A310-57-2082, Revision 03, dated November 15, 2010, 
except as required by paragraph (m)(2) of this AD. Do all applicable

the applicable intervals, including the compliance times for post 
temporary repair inspections, specified in Paragraph 1.E., 
``Compliance,'' of Airbus Mandatory Service Bulletin A310-57-2082, 
Revision 03, dated November 15, 2010, except as specified in 
paragraph (m)(3) of this AD. The temporary repair of cracks, as 
identified in Airbus Mandatory Service Bulletin A310-57-2082, 
Revision 03, dated November 15, 2010, does not constitute 
terminating action for the repetitive inspections required by this 
AD. Accomplishment of the inspection required by this paragraph 
terminates the requirements of paragraphs (g) and (h) of this AD. 
Doing the modification specified in paragraph (j) of this AD 
terminates the repetitive inspections required by this paragraph.

(l) New Permanent Repair

    For airplanes on which the temporary repair as specified in 
Airbus Mandatory Service Bulletin A310-57-2082 has been done, within 
the applicable time specified in Paragraph 1.E., ``Compliance,'' of

Accomplishment Instructions of Airbus Mandatory Service Bulletin 
A310-57-2082, Revision 03, dated November 15, 2010, except as 
provided by paragraph (m)(2) of this AD.

(m) New Exceptions to Service Information

    (1) Where Paragraph 1.E., ``Compliance,'' of Airbus Mandatory 
Service Bulletin A310-57-2082, Revision 03, dated November 15, 2010, 
specifies a compliance time ``from receipt of this service 
bulletin,'' this AD requires compliance within the specified 
compliance time after the effective date of this AD.
    (2) Where Airbus Mandatory Service Bulletin A310-57-2082, 
Revision 03, dated November 15, 2010, specifies to contact Airbus 
for repair: Before further flight, repair the crack using a method 
approved by either the Manager, International Branch, ANM-116; or 
EASA (or its delegated agent).
    (3) Where Paragraph 1.E., ``Compliance,'' of Airbus Mandatory 
Service Bulletin A310-57-2082, Revision 03, dated November 15, 2010, 
specifies to contact Airbus for inspection intervals, this AD 
requires using an inspection interval approved by either the 
Manager, International Branch, ANM-116; or EASA (or its delegated 
agent).
