Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A310 series airplanes. That AD currently requires repetitive inspections of the fuselage skin to detect corrosion or fatigue cracking around and under the chafing plates of the wing root; repetitive inspections for fatigue cracking of frame 39, stringer 35; and corrective actions if necessary. The existing AD also provides for an optional terminating action for certain repetitive inspections, except for certain areas where corrosion was detected and reworked. This new AD reduces the intervals for accomplishing repetitive inspections in a certain area. 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 detect and correct fatigue cracks and corrosion around and under the chafing plates of the wing root, which could result in reduced structural integrity of the airplane.

DATES:

This AD becomes effective August 25, 2009.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of August 25, 2009.

The Director of the Federal Register previously approved the incorporation by reference of Airbus Service Bulletin A310-53-2070, dated October 3, 1994, on June 3, 1998 (63 FR 23377, April 29, 1998).

SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2004-14-06, amendment 39-13715 (69 FR 41401, July 9, 2004). The existing AD applies to certain Airbus Model A310 series airplanes. That NPRM was published in the Federal Register on November 13, 2008 (73 FR 67110). That NPRM proposed to continue to require repetitive inspections of the fuselage skin to detect corrosion or fatigue cracking around and under the chafing plates of the wing root; repetitive inspections for fatigue cracking of frame 39, stringer 35; and corrective actions if necessary. That NPRM also proposed to continue to provide for an optional terminating action for certain repetitive inspections, except for certain areas where corrosion was detected and reworked. In addition, that NPRM proposed to reduce the intervals for accomplishing the repetitive inspections in a certain area.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been received on the NPRM. FedEx supports the NPRM.

Revisions to Paragraphs (f), (h), (i), and (j) of This AD

We have revised paragraph (h) of this AD to give credit for actions done in accordance with Airbus Service Bulletin A310-53-2070, Revision 1, dated September 23, 1996. We also added Airbus Service Bulletin A310-53-2069, Revision 06, dated May 22, 2007, as an acceptable source of service information for compliance with the requirements of paragraphs (f) and (i) of this AD. We have also revised paragraph (j) of this AD to include a new Table 1 to specify the number, revision, and date of each service bulletin for which no reporting is required.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.

Costs of Compliance

This AD affects about 69 Model A310 series airplanes of U.S. registry. The actions that are required by AD 2004-14-06 and retained in this AD take about 68 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 $375,360, or $5,440 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

We have determined that this AD will not have federalism implications under Start Printed Page 35778Executive 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.

If any discrepancy is found, prior to further flight, accomplish follow-on corrective actions (i.e., removal of corrosion, corrosion protection, high frequency eddy current inspection, x-ray inspection), as applicable, in accordance with the applicable service bulletin. Repeat the inspections thereafter at the intervals specified in the applicable service bulletin. After August 13, 2004 (the effective date of AD 2004-14-06), repeat the inspections thereafter at the intervals specified in Airbus Service Bulletin A310-53-2069, Revision 04, dated November 8, 2000; Airbus Service Bulletin A310-53-2069, Revision 05, dated November 12, 2002; or Airbus Service Bulletin A310-53-2069, Revision 06, dated May 22, 2007.

Where differences in the compliance times or corrective actions exist between the service bulletin and this AD, the AD prevails.

Optional Terminating Action

(h) Except as provided by paragraph (i) of this AD: Accomplishment of the replacement of the stainless steel chafing plates with new chafing plates made of aluminum alloy, in accordance with Airbus Service Bulletin A310-53-2070, Revision 02, dated November 8, 2000; or the original issue, dated October 3, 1994; constitutes terminating action for the repetitive inspections required by paragraph (f) of this AD. Actions done in accordance with Airbus Service Bulletin A310-53-2070, Revision 1, dated September 23, 1996, are acceptable for compliance with actions required by this AD.

Continuation of Repetitive Inspections

(i) Except as provided by paragraphs (k) and (l) of this AD: Within 30 days after August 13, 2004, do a review of the airplane maintenance records to determine if any corrosion was detected and reworked on the left and/or right side of frame 39, stringer 35, during the accomplishment of any corrective action or repair specified in paragraphs (f) or (g) of this AD. If any corrective action or repair has been accomplished in this area, perform an inspection for fatigue cracking of frame 39, stringer 35, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-53-2069, Revision 06, dated May 22, 2007; Revision 05, dated November 12, 2002; or Revision 04, dated November 8, 2000. Do the initial inspection at the threshold specified in Figure 1 of the service bulletin, or within 30 days after August 13, 2004, whichever is later. Repeat the inspection thereafter at the intervals specified in Figure 1 of the service bulletin. If any discrepancy is found, prior to further flight, accomplish the applicable follow-on corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-53-2069, Revision 06, dated May 22, 2007; Revision 05, dated November 12, 2002; or Revision 04, dated November 8, 2000.
