2010-2192. Airworthiness Directives; The Boeing Company Model 767-200, -300, and -300F Series Airplanes

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 existing AD currently requires repetitive detailed and eddy current inspections to detect cracks or corrosion of certain midspar fuse pins, and corrective actions if necessary. That AD also provides optional terminating action, which ends the repetitive inspections. This new AD requires reduced intervals for certain repetitive inspections. This AD results from a report of a fractured midspar fuse pin. We are issuing this AD to prevent loss of the strut and engine due to corrosion damage and cracking of both fuse pins on the same strut.

DATES:

This AD becomes effective February 19, 2010.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of February 19, 2010.

The Director of the Federal Register previously approved the incorporation by reference of a certain publication listed in the AD as of March 5, 2001 (66 FR 8085, January 29, 2001).

The Director of the Federal Register previously approved the incorporation by reference of a certain other publication listed in the AD as of October 17, 2000 (65 FR 58641, October 2, 2000).

SUPPLEMENTARY INFORMATION:

Discussion

On January 22, 2003, we issued AD 2003-03-02, amendment 39-13026 (68 FR 4374, January 29, 2003). That AD applies to certain Model 767-200, -300, and -300F airplanes. That AD requires repetitive detailed and eddy current inspections to detect cracks and corrosion of certain midspar fuse pins, and corrective actions if necessary. That AD also provides optional terminating action, which ends the repetitive inspections. That AD resulted from a report of a fractured outboard midspar fuse pin (part number (P/N) 311T3102-1) of the left engine pylon, which was found during a scheduled maintenance visit. The fuse pin also had corrosion on the pin and within the bore. The actions specified in that AD are intended to prevent loss of the strut and engine due to corrosion damage and cracking of both fuse pins on the same strut.

Actions Since AD Was Issued

Since we issued that AD, we received a report that a fractured midspar fuse pin was found on a Model 767-300 airplane with CF6-80C2 engines. The airplane had accumulated 16,054 flight cycles and neither Boeing Service Bulletin 767-54-0069 (required by AD 2000-19-09, amendment 39-11910; AD 2001-02-07, amendment 39-12091; and AD 2001-06-12, amendment 39-12159) nor Boeing Service Bulletin 767-54-0081 (required by AD 2001-06-12) had been incorporated. (ADs 2001-02-07 and 2001-06-12 have been superseded by AD 2004-16-12, amendment 39-13768.) The fractured midspar fuse pin was found during routine maintenance on the outboard side of the number one pylon, prior to the next scheduled midspar fuse pin inspection in accordance with Boeing Alert Service Bulletin 767-54A0062, Revision 5, dated November 11, 2002 (referenced in AD 2003-03-02). Further inspection revealed a cracked midspar fuse pin on the inboard side of the number one pylon. Subsequent inspection of both midspar fuse pins revealed discrepant circumferential machining grooves on the fuse pin main bore surface, in addition to longitudinal cracks. In addition, eddy current inspection of the midspar fuse pins in accordance with the requirements of Revision 5 of this service bulletin will not reveal the maximum allowable roughness of the fuse pin main bore surface. Metallurgical analysis determined the fuse pin fracture or crack origins coincided with the discrepant machining groove locations, in all cases. Stresses due to pin ovalization contributed to the longitudinal cracking of the midspar fuse pins.

Relevant Service Information

We have reviewed Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated November 5, 2009. The service bulletin describes procedures similar to those in Boeing Alert Service Bulletin 767-54A0062, Revision 5, dated November 11, 2002 (referred to in AD 2003-03-02 as a method of accomplishing the required actions), but with reduced repetitive inspection intervals. Revision 6 of this service bulletin does provide optional corrective actions for certain conditions; a repair of the midspar fuse pin may be done instead of replacing the pin. The repair includes contacting Boeing for repair instructions and doing the repair. Revision 6 of this service bulletin also revises the corrective actions for corrosion by basing the condition on corrosion found on a non-critical surface or any surface other than a non-critical surface.

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 2003-03-02. This new AD retains certain requirements of the existing AD. This AD also reduces intervals for repeat inspections and requires accomplishing the actions specified in Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated November 5, 2009, described previously, except as discussed under “Difference Between the AD and the Service Bulletin.”

Difference Between the AD and the Service Bulletin

Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated November 5, 2009, specifies to “Contact Boeing for repair instructions * * *.” This AD would require repairing in accordance with a method approved by the Manager, Seattle Aircraft Certification Office, FAA.

Change to Existing AD

This AD would retain certain requirements of AD 2003-03-02. Since AD 2003-03-02 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this AD, as listed in the following table:

Revised Paragraph Identifiers

Requirement in AD 2003-03-02	Corresponding requirement in this AD
paragraph (h)	paragraph (g)
paragraph (i)	paragraph (h)
paragraph (j)	paragraph (i)
paragraph (k)	paragraph (j)
paragraph (l)	paragraph (k)
paragraph (m)	paragraph (l)
paragraph (n)	paragraph (m)

FAA's Justification and Determination of the Effective Date

A fractured midspar fuse pin was discovered after the issuance of AD 2003-03-02. Fractured, corroded, or cracked midspar fuse pins could lead to the separation of the strut and engine from the airplane. Because of our requirement to promote safe flight of civil aircraft and thus, the critical need to assure the structural integrity of the engine strut 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-2010-0031; Directorate Identifier 2009-NM-266-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, 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 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.
