AD 2005-25-20

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330-300, A340-200, and 340-300 series airplanes. The existing AD requires repetitive inspections to detect cracking of the fuselage skin in the area of the VHF2 antenna, and repair if necessary. The existing AD also provides for optional terminating action for the repetitive inspections. This new AD requires accomplishment of the previously optional terminating action, and revises the applicability by removing certain airplanes. This AD is prompted by the need to change the applicability of the existing AD and to mandate the formerly optional terminating action. We are issuing this AD to prevent cracking of the fuselage skin in the area of the VHF2 antenna, which could result in depressurization of the airplane.

DATES: Effective December 29, 2005.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 29, 2005.
The incorporation by reference of certain other publications, as listed in the regulations, was approved previously by the Director of the Federal Register as of April 12, 2000 (65 FR 12075, March 8, 2000).

We must receive comments on this AD by February 13, 2006.

Final rule; request for comments.

On February 29, 2000, the FAA issued AD 2000-05-04, amendment 39-11613 (65 FR 12075, March 8, 2000). That AD applies to certain Airbus Model A330 and A340 series airplanes and requires repetitive inspections to detect cracking of the fuselage skin in the area of the VHF2 antenna, and repair if necessary. That AD also provides for optional terminating action for the repetitive inspections. That action was prompted by issuance of mandatory continuing airworthiness information by the French civil aviation authority. We issued that AD to detect and correct such cracking, which could result in depressurization of the airplane.

Actions Since Issuance of Previous Rule

Since we issued AD 2000-05-04, the Direction G n rale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, has revised the parallel French airworthiness directives to exclude airplanes that have been modified by Airbus Modification 46025, 46849, or 46900; and to mandate the previously optional terminating action.

Explanation of Relevant New Service Information

Airbus has issued the following service bulletins:

The revised service bulletins for the terminating modification are essentially the same: They remove certain life limits, but add no new procedures. The DGAC classified Service Bulletins A330-53-3097 and A340-53-4108 as mandatory and issued Frenchairworthiness directives 2001-041(B) and 2001-040(B), both dated January 24, 2001, to ensure the continued airworthiness of these airplanes in France.

Airbus has also issued Service Bulletins A330-53-3112 and A340-53- 4124, both dated February 15, 2001, which describe procedures for relocating the VHF2 antenna between stringer 51 and stringer 52, away from the outlet air flow of the air conditioning packs. These service bulletins provide for alternative procedures to those specified in Service Bulletins A330-53-3097 and A340-53-4108 to eliminate the need for the repetitive inspections. The DGAC has approved Service Bulletins A330-53-3112 and A340-53-4124 and considers them optional terminating action for the repetitive inspections.

FAA's Determination and Requirements of This AD

These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. According to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States.

For this reason, we are issuing this AD to supersede AD 2000-05-04. This AD retains the requirements of the existing AD, requires accomplishment of the previously optional terminating action, and adds an alternative terminating action. This AD removes certain airplanes from the applicability of the existing AD. The actions are required to be done in accordance with the service bulletins described previously, except as described below.

Additional Changes to AD

We have made the following additional changes to the AD:

1. We revised the applicability in this AD by updating the service bulletin references to match the applicability of the corresponding French airworthiness directives.

2. The FAA has changed all references to a "detailed visual inspection" in the existing AD to "detailed inspection" in this new AD. Note 1 in this AD defines that inspection.

3. We have reviewed the figures we have used over the past several years to calculate AD costs to operators. To account for various inflationary costs in the airline industry, we find it necessary to increase the labor rate used in these calculations from $60 per work hour to $65 per work hour. The cost impact information, below, reflects this increase in the specified hourly labor rate.

4. Since we issued AD 2000-05-04, the type certificate data sheet for affected airplanes has been updated. We have revised the applicability of this AD accordingly.

Differences Between AD and Service Bulletins

The revised service bulletins provide repair procedures for cracks up to 14.17 inches. However, no datahave been presented that would justify the acceptability of the increased crack length. This AD requires that operators contact the FAA or DGAC for repair instructions of cracks exceeding 9.45 inches.

Costs of Compliance

None of the airplanes affected by this action are on the U.S. Register. All airplanes affected by this AD are currently operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, we consider this AD necessary to ensure that the unsafe condition is addressed if any affected airplane is imported and placed on the U.S. Register in the future.

The following table provides the estimated costs to comply with this AD for any affected airplane that might be imported and placed on the U.S. Register in the future.

FAA's Determination of the Effective Date

No airplane affected by this AD is currently on the U.S. Register. Therefore, providing notice and opportunity for public comment is unnecessary before this AD is issued, and this AD may be made effective in less than 30 days after it is published in the Federal Register.

Comments Invited

Although this is a final rule that was not preceded by notice and an opportunity for public comment, we invite you to submit any relevant written data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include "Docket No. FAA-2005- 23251; Directorate Identifier 2002-NM-20-AD" at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD. We will consider all comments received by the closing date and may amend the AD in light of those comments.

We will post all comments we receive, without change, to http://dms.dot.gov , including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of our docket web site, anyone can find and read the comments in any of our dockets, including the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You can review the DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477-78), or you can visit http://dms.dot.gov.

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 have determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 that the 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 AD. See the ADDRESSES section for a location to examine the regulatory evaluation.
