AGENCY:

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

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is superseding an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, and -300F series airplanes. The Start Printed Page 42593existing AD currently requires repetitive inspections to detect discrepancies of the 8 aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. The existing AD also requires repetitive inspections for cracks of the closeout angle that covers the 2 aft-most fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. The existing AD also provides an optional terminating action for the repetitive inspections. This new AD reduces the compliance times for doing the inspections. This AD results from reports of cracks in the midspar fitting tangs. We are issuing this AD to detect and correct fatigue cracking in the primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine.

DATES:

This AD becomes effective August 6, 2010.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 6, 2010.

We must receive any comments on this AD by September 7, 2010.

Discussion

On September 13, 2005, we issued AD 2005-19-23, amendment 39-14288 (70 FR 55519, September 22, 2005). That AD applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD requires repetitive inspections to detect discrepancies of the eight aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. That AD also requires repetitive inspections for cracks of the closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. That AD also provides an optional terminating action for the repetitive inspections. That AD resulted from a report of a crack in a closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting, and the discovery of a crack in the lower tang of the midspar fitting under the cracked closeout angle. The actions specified in that AD are intended to prevent fatigue cracking in the primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine.

Actions Since AD Was Issued

Since we issued that AD, we received two reports of cracks in the midspar fitting tangs. The first report indicated severed upper and lower tangs at the aft two fastener locations in the Number 1 pylon inboard midspar fitting. The cracks were found during a routine check of a Model 767-300 airplane at approximately 92,205 total flight hours and 14,969 total flight cycles. This airplane had incurred 408 flight cycles from the previous inspection. The second report indicated cracks in the Number 1 pylon inboard midspar fitting lower tang, between the aft two fastener holes, on a Model 767-300 airplane at approximately 94,176 total flight hours and 15,405 total flight cycles. This airplane had incurred 830 cycles from the previous inspection.

AD 2005-19-23 specified repetitive inspection intervals between 1,500 flight cycles and 16,000 flight cycles, depending on the inspection type and location. We have determined that the affected airplanes must be inspected within 400 flight cycles since the previous inspection and, for those airplanes that have not yet been inspected, the compliance time threshold of 10,000 total flight cycles specified in AD 2005-19-23 must be reduced to 8,000 total flight cycles. We have also determined that repetitive inspection intervals must be reduced to 400 flight cycles and 6,000 flight cycles, depending on the inspection type.

Relevant Service Information

We have reviewed Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010. We referred to Boeing Alert Service Bulletin 767-54A0101, Revision 4, dated February 10, 2005, for doing certain actions required by AD 2005-19-23. The procedures in Revision 5 are similar to the procedures in Revision 4. Revision 5 reduces the compliance times for doing the procedures.

We have also reviewed Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated November 5, 2009; and Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008; which are the latest versions of certain service bulletins referred to in AD 2005-19-23 as additional sources of guidance for doing the terminating action. Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, refers to Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated November 5, 2009; and Boeing Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008; as additional sources of guidance for doing the terminating action in Part 4 of the alert service bulletin.

FAA's Determination and Requirements of This AD

The unsafe condition described previously is likely to exist or develop on other airplanes of the same type design. For this reason, we are issuing this AD to supersede AD 2005-19-23. This AD requires accomplishing the actions specified in Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, described previously, except as discussed under “Differences Between the AD and the Service Bulletin.”

Differences Between the AD and the Service Bulletin

The service bulletin specifies to contact the manufacturer for instructions on how to repair certain conditions, but this AD requires repairing those conditions in one of the following ways:

  • In accordance with a method that we approve; or
  • Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom we have authorized to make those findings.

Steps 4.a. and 4.b. of Part 2 of the Work Instructions of Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, specify actions if cracking is found and the hole size is either greater than 0.5322 inch or less than 0.5322 inch but not if the hole size equals 0.5322 inch. This AD specifies that if cracking is found and the hole size equals 0.5322 inch, then the terminating action specified in step 4.a. of Part 2 of the Work Instructions of Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, must be accomplished.

Interim Action

We consider this AD interim action. We are currently considering additional rulemaking to expand the inspection area.

FAA's Justification and Determination of the Effective Date

Fatigue cracking in the primary strut structure could result in reduced structural integrity of the strut and consequent separation of the strut and engine. Because of our requirement to promote safe flight of civil aircraft and thus, the critical need to ensure the structural integrity of the pylon structure and midspar fittings and the short compliance time involved with this action, this AD must be issued immediately.

Because an unsafe condition exists that requires the immediate adoption of this AD, we find that notice and opportunity for prior public comment hereon are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2010-0671; Directorate Identifier 2010-NM-142-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

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, Start Printed Page 42595Part 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 and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
