ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A300 and A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called A300-600 series airplanes). The existing AD currently requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new and revised structural inspections and inspection intervals. Since we issued that AD, Airbus has revised certain ALI documents, which require more restrictive maintenance requirements and airworthiness limitations. This proposed AD would revise the maintenance program to incorporate the limitations section. We are proposing this AD to prevent fatigue cracking, damage, or corrosion in principal structural elements, which could result in reduced structural integrity of the airplane.

DATES:

We must receive comments on this proposed AD by December 24, 2012.

Discussion

On May 2, 2011, we issued AD 2011-10-17, Amendment 39-16698 (76 FR 27875, May 13, 2011). That AD required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2011-10-17, Amendment 39-16698 (76 FR 27875, May 13, 2011), Airbus has revised certain ALI documents, which require more restrictive maintenance requirements and airworthiness limitations. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011-0198, dated October 19, 2011 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The airworthiness limitations applicable to the Damage Tolerant Airworthiness Limitation Items (DT ALIs) are currently listed in Airbus ALI Documents, which are referenced in the A300, A310 and A300-600 Airworthiness Limitations Section (ALS) Part 2.

Airbus have recently revised the A300-600 and A310 ALI Documents, and these issues have been approved by EASA. The Airbus A300-600 ALI Document issue 13 and temporary revision (TR) 13.1 and the A310 ALI document issue 08 introduce more restrictive maintenance requirements and airworthiness limitations, which have been identified as mandatory actions for continued airworthiness.

EASA AD 2009-0155 [which corresponds to FAA AD 2011-10-17, Amendment 39-16698 (76 FR 27875, May 13, 2011)] required compliance with the maintenance requirements and associated airworthiness limitations defined in the following documents:

—AIRBUS A300 ALI Document issue 04,

—AIRBUS A310 ALI Document issue 07, and

—AIRBUS A300-600 ALI Document issue 12.

For the reasons described, this EASA AD retains the requirements of EASA AD 2009-0155, which is superseded, and requires compliance with the airworthiness limitations defined in the Airbus A300-600 ALI Document issue 13 and TR13.1, and the A310 ALI document issue 08.

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

Relevant Service Information

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

  • Airbus A310 Airworthiness Limitation Items Document, AI/SE-M2/95A.1309/07, Issue 8, dated October 2010 (for Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes).
  • Airbus A300-600 Airworthiness Limitation Items Document, AI/SE-M2/95A.1310/07, Issue 13, dated October 2010 (Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes).
  • Airbus Temporary Revision 13.1, dated February 2011, to the Airbus A300-600 Airworthiness Limitation Items Document, AI/SE-M2/95A.1310/07, Issue 13, dated October 2010 (for Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes).

FAA's Determination and Requirements of This Proposed AD

These products have 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 these same type designs.

This proposed AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (u)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 170 products of U.S. registry.

The actions that are required by AD 2011-10-17, Amendment 39-16698 (76 FR 27875, May 13, 2011), and retained in this proposed AD take about 1 work-hour 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 $85 per product.

We estimate that it would take about 1 work-hour 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 $14,450, or $85 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);

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.

List of Subjects in 14 CFR Part 39

The Proposed Amendment
