Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.

SUMMARY:

We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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 airworthiness limitations applicable to the Certification Maintenance Requirements (CMR) are given in Airbus A330 ALS Part 3, which is approved by the European Aviation Safety Agency (EASA).

The revision 02 of Airbus A330 ALS Part 3 introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with this revision constitutes an unsafe condition.

* * * * *

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.

Discussion

We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was published in the Federal Register on January 29, 2010 (75 FR 4710). That earlier NPRM proposed to supersede AD 2007-05-08, Amendment 39-14969 (72 FR 96580, March 5, 2007), to require actions intended to address the unsafe condition for the products listed above.

Since that NPRM was issued, Airbus has released new service information. In addition, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010-0048, dated March 19, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The airworthiness limitations are currently distributed in the Airbus A330 Airworthiness Limitations Section (ALS).

The airworthiness limitations applicable to the Certification Maintenance Requirements (CMR) are given in Airbus A330 ALS Part 3, which is approved by the European Aviation Safety Agency (EASA).

The revision 02 of Airbus A330 ALS Part 3 introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with this revision constitutes an unsafe condition.

This new AD retains the requirements of EASA AD 2008-0138, which is superseded [EASA AD 2008-0138 superseded EASA AD 2006-0224, which corresponds to FAA AD 2007-05-08; FAA AD 2007-05-08 also contains similar actions for Model A340 airplanes], and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A330 ALS Part 3 revision 02.

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

Comments

We have considered the following comments received on the earlier NPRM.

Request To Update Service Information

Air Transport Association (ATA), on behalf of its member Delta, requests that we update the NPRM to reference Airbus A330 ALS Part 3—Certification Maintenance Requirements, Revision 02, including Appendices 1 and 2, dated December 16, 2009.

We agree to reference Airbus A330 ALS Part 3—Certification Maintenance Requirements, Revision 02, including Appendices 1 and 2, dated December 16, 2009, as an appropriate source of service information. Airbus Airworthiness Limitations Section (ALS) Part 3, Revision 02, dated December 16, 2009, contains more restrictive maintenance requirements and airworthiness limitations. We have issued this supplemental NPRM to provide the public with opportunity to comment.

Change to Proposed Applicability

We have revised the applicability statement of this supplemental NPRM to remove the Airbus Model A340-200, -300, -500, and -600 series airplanes. We have issued AD 2010-01-07, Amendment 39-16165 (75 FR 1538, January 12, 2010), and that AD applies to Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes. That AD addresses the identified unsafe condition for those airplanes.

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.

Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this proposed AD.

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.

Explanation of Change to Costs of Compliance

Since issuance of the original NPRM, we have increased the labor rate used in the Costs of Compliance from $80 per work-hour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate.

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 2007-05-08 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 Start Printed Page 46863proposed 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 $4,930, 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); 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.

The Proposed Amendment

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

Start Part

PART 39—AIRWORTHINESS DIRECTIVES

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

Start Authority

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

End Authority
[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 August 30, 2010.

Affected ADs

(b) This 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 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 airworthiness limitations applicable to the Certification Maintenance Requirements (CMR) are given in Airbus A330 ALS Part 3, which is approved by the European Aviation Safety Agency (EASA).

The revision 02 of Airbus A330 ALS Part 3 introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with this revision constitutes an unsafe condition.

* * * * *

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.

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) 25-1529-1A.

Restatement of Requirements of AD 2007-05-08, With Requirements for Model A340 Airplanes Removed

Revise the Airworthiness Limitations Section of the Instructions for Continued Airworthiness
