AD 2005-01-01

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320-200 series airplanes, that currently requires repetitive inspections to detect loose, missing, or discrepant rivets in specified areas of the door frames of the overwing emergency exits; measurement of the grip length of all rivets in the specified areas; and corrective action if necessary, which terminates the repetitive inspections. This new amendment also requires an inspection for correct dimensions of the interior countersinks of the rivet holes, and related corrective action. The actions specified by this AD are intended to prevent loose, missing, or discrepant rivets, which could lead to reduced structural integrity of the door frames of the overwing emergency exits. This action is intended to address the identified unsafe condition.

Final rule.

2005-01-01 Airbus: Amendment 39-13925. Docket 2003-NM-135-AD. Supersedes AD 2002-04-10, Amendment 39-12667.

Effective Date

(h) This amendment becomes effective on February 9, 2005.

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 2002-04-10, amendment 39-12667 (67 FR 9392, March 1, 2002), which is applicable to certain Airbus Model A319 and A320-200 series airplanes, was published in the Federal Register on April 7, 2004 (69 FR 18304). The action proposed to retain the existing requirements for repetitive inspections for loose, missing, or discrepant rivets in specified areas of the door frames of the overwing emergency exits; and measurement of the grip length of all rivets in the specified areas; and corrective action if necessary, which terminates the repetitive inspections. The proposed AD also proposed to add an inspection for correct dimensions of the interior countersinks of the rivet holes, and related corrective action.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been submitted on the proposed AD. The commenters support the proposed AD.

Conclusion

We have carefully reviewed the available data, including the comments that have been submitted, and determined that air safety and the public interest require adopting the AD as proposed.

Cost Impact

This AD affects about 168 airplanes of U.S. registry.

The inspections required by AD 2002-04-10 take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the cost impact of those inspections is estimated to be $65 per airplane, per inspection cycle.

The new inspection required by this AD takes about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the cost impact of the new inspection on U.S. operators is estimated to be $10,920, or $65 per airplane.

The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the requirements of this AD, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions.

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 Impact

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this action (1) is not a "significant regulatory action" under Executive Order 12866; (2) is not a "significant rule" under 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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
