Start Preamble

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 Générale 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.Start Printed Page 8056

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.
