Rule

Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes

Action

Final Rule.

Summary

The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B2, B4-100, and B4-200 series airplanes. That AD currently requires supplemental structural inspections to detect fatigue cracking, and repair of cracked structure. This new AD requires revising the maintenance program by incorporating new and revised supplemental structural inspections, inspection intervals, and repairs; and repair of any damaged, cracked, or corroded structure; which would end the existing supplement structural inspections. This AD results from a review of service history and reports received from the current supplemental structural inspection document program. We are issuing this AD to prevent reduced structural integrity of these airplanes due to fatigue cracking.

Examining the Docket Back to Top

You may examine the airworthiness directive (AD) docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section.

Discussion Back to Top

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 96-13-11, amendment 39-9679 (61 FR 35122, July 5, 1996). The existing AD applies to all Airbus Model A300 B2, B4-100, and B4-200 series airplanes. That NPRM was published in the Federal Register on September 26, 2006 (71 FR 56058). That NPRM proposed to continue to require supplemental structural inspections to detect fatigue cracking, and repair of cracked structure. That NPRM also proposed to require revising the maintenance program by incorporating new and revised supplemental structural inspections, inspection intervals, and repairs; and repair of any damaged, cracked, or corroded structure; which would end the existing supplement structural inspections.

Comments Back to Top

We provided the public the opportunity to participate in the development of this AD. We have considered the comment received.

Request for Change to the Applicability Back to Top

Airbus, the manufacturer, requests that we exclude the A300-600 series airplanes from the AD applicability. The commenter refers us to page 1-A of Airbus A300 Airworthiness Limitation Items Document SEM2/95A.1090/05, Issue 3, dated September 2005, as revised by Airbus Temporary Revision 3.1, dated April 2006, which does not include A300-600 series airplanes.

We agree with the commenter's request. We do not want any reader of this AD to infer that A300-600 series airplanes are included, and have changed the applicability to exclude those airplanes in paragraph (c) of this AD.

Conclusion Back to Top

We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance Back to Top

The following table provides the estimated costs for U.S. operators to comply with this AD.

Estimated Costs Back to Top
Action Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.-registered airplanes Fleet cost
Implementation of supplemental structural inspection program (required by AD 96-13-11) 597 $80 None $47,760 29 $1,385,040
Revision of the FAA-approved maintenance program (new action) 10 80 None 800 29 23,200

Authority for This Rulemaking Back to Top

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 Back to Top

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 this AD:

(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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39 Back to Top

Adoption of the Amendment Back to Top

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

PART 39—AIRWORTHINESS DIRECTIVES Back to Top

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 Federal Aviation Administration (FAA) amends § 39.13 by removing amendment 39-9679 (61 FR 35122, July 5, 1996) and by adding the following new airworthiness directive (AD):

2007-04-11Airbus: Amendment 39-14943. Docket No. FAA-2006-25890; Directorate Identifier 2006-NM-115-AD.

Effective Date Back to Top

(a) This AD becomes effective April 3, 2007.

Affected ADs Back to Top

(b) This AD supersedes AD 96-13-11.

Applicability Back to Top

(c) This AD applies to all Airbus Model A300 B2 and B4 series airplanes, certificated in any category, excluding A300-600 series airplanes.

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 (x) 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.

Unsafe Condition Back to Top

(d) This AD results from a review of service history and reports received from the current supplemental structural inspection document program. We are issuing this AD to prevent reduced structural integrity of these airplanes due to fatigue cracking.

Compliance Back to Top

(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
