2010-1924. Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes and A340-200, -300, -500, and -600 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 that would supersede an existing AD. 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: The revision 00 of the AIRBUS A330 ALS [Airworthiness Limitations Section] Part 3 was issued primarily to introduce two new CMR [Certification Maintenance Requirements] tasks, referenced 282400-G0001-1-C and 282400-P0001-1-C. ALS Part 3 Revision 01 introduces more restrictive requirements for aircraft configurations already in service. The unsafe condition is safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition. 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 March 15, 2010.

Discussion

On February 22, 2007, we issued AD 2007-05-08, Amendment 39-14969 (72 FR 9658, March 5, 2007). That AD required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2007-05-08, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2008-0138, dated July 23, 2008 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The Certification Maintenance Requirements (CMR) were given in the AIRBUS A330 CMR Document up to revision 19, and referenced in the Airworthiness Limitations Section (ALS) Part 3 Revision 00. The content of the CMR Document has been recently transferred into the ALS Part 3, which is approved by the European Aviation Safety Agency (EASA).

The revision 00 of the AIRBUS A330 ALS Part 3 was issued primarily to introduce two new CMR tasks, referenced 282400-G0001-1-C and 282400-P0001-1-C. The compliance times associated to these two tasks are re-stated in the Record Of Revisions (ROR) of the ALS Part 3 Revision 01.

ALS Part 3 Revision 01 introduces more restrictive requirements for aircraft configurations already in service.

EASA AD 2006-0224 [which corresponds to FAA AD 2007-05-08 and includes Model A340 airplanes], mandating compliance with the requirements of the A330 CMR Document at issue 19, is therefore superseded by this AD.

The unsafe condition is safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition. The required actions also include deleting Airbus A330 CMR Task 272400-00001-1-C and adding new Task 272400-00003-1-C. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued Airbus A330 ALS Part 3—Certification Maintenance Requirements (CMR), Revision 01, including Appendices 1 and 2, dated May 7, 2008. 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 43 products of U.S. registry.

The actions that are required by AD 2007-05-08 and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the currently required actions is $80 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 $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $3,440, or $80 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.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
• Aviation safety
• Incorporation by reference
• Safety

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13

[Amended]

2. The FAA amends § 39.13 by removing Amendment 39-14969 (72 FR 9658, March 5, 2007) and adding the following new AD:

Airbus: Docket No. FAA-2009-1212; Directorate Identifier 2008-NM-167-AD.

Comments Due Date

(a) We must receive comments by March 15, 2010.

Affected ADs

(b) The proposed AD supersedes AD 2007-05-08, Amendment 39-14969.

Applicability

(c) This AD applies to all Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 series airplanes; Model A340-211, -212, -213, -311, -312, -313 series airplanes; and Model A340-541, and -642 series airplanes, certificated in any category; all serial numbers.

Subject

(d) Air Transport Association (ATA) of America Code 05.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

The Certification Maintenance Requirements (CMR) were given in the AIRBUS A330 CMR Document up to revision 19, and referenced in the Airworthiness Limitations Section (ALS) Part 3 Revision 00. The content of the CMR Document has been recently transferred into the ALS Part 3, which is approved by the European Aviation Safety Agency (EASA).

The revision 00 of the AIRBUS A330 ALS Part 3 was issued primarily to introduce two new CMR tasks, referenced 282400-G0001-1-C and 282400-P0001-1-C. The compliance times associated to these two tasks are re-stated in the Record of Revisions (ROR) of the ALS Part 3 Revision 01.

ALS Part 3 Revision 01 introduces more restrictive requirements for aircraft configurations already in service.

EASA AD 2006-0224 [which corresponds to FAA AD 2007-05-08 and includes Model A340 airplanes], mandating compliance with the requirements of the A330 CMR Document at issue 19, is therefore superseded by this AD.

The unsafe condition is safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition. The required actions also include deleting Airbus A330 CMR Task 272400-00001-1-C and adding new Task 272400-00003-1-C.

Note 1:

This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (h) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in Advisory Circular (AC) 25-1529-1.

Restatement of Requirements of AD 2007-05-08
