Airworthiness Directives; Airbus Model A310 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: The FAA is superseding an existing airworthiness directive

(AD) that applies to all Airbus Model A310 series airplanes. That AD currently requires repetitive detailed inspections to detect cracks propagating from the fastener holes that attach the left- and right- hand pick-up angles at frame 40 to the wing lower skin and fuselage panel, and corrective actions if necessary. This new AD revises the intervals for accomplishing the repetitive detailed inspections and provides for an optional terminating modification for the repetitive inspections. This new AD also revises the applicability of the AD to remove certain airplanes. This AD results from mandatory continuing airworthiness information originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to prevent reduced structural integrity of the airplane due to fatigue damage, and consequent cracking of the pick-up angles at frame 40.

DATES: This AD is effective April 2, 2009.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 2, 2009.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that supersedes AD 2000-26-14, amendment 39-12064 (66 FR 1031, January 5, 2001). The existing AD applies to all Airbus Model A310 series airplanes. That

NPRM was published in the Federal Register on August 26, 2008 (73 FR 50250). A correction to that NPRM was published in the Federal Register on September 8, 2008 (73 FR 51961). That NPRM proposed to continue to require repetitive detailed inspections to detect cracks propagating from the fastener holes that attach the left- and right-hand pick-up angles at frame 40 to the wing lower skin and fuselage panel, and corrective actions if necessary. That NPRM also proposed to revise the intervals for accomplishing the repetitive detailed inspections and provided for an optional terminating modification for the repetitive inspections. That NPRM also proposed to revise the applicability of the

AD to remove certain airplanes.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

This AD affects about 68 Model A310 series airplanes of U.S. registry.

The inspections that are required by AD 2000-26-14 and retained in this AD take about 2 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the currently required actions is $10,880, or $160 per airplane, per inspection cycle.

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

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.

You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.

Adoption of the Amendment 0

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

PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows:

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

Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing amendment 39-12064 (66 FR 1031, January 5, 2001) and by adding the following new AD: 2009-01-09 Airbus: Amendment 39-15788. Docket No. FAA-2008-0908;

Note 2: For the purposes of this AD, a detailed inspection is defined as: ``An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.''
