AD 2000-19-09 Airworthiness Directives; Boeing Model 767 Series Airplanes Powered by Rolls-Royce RB211 Series Engines

Models named: 767 series. Read the applicability below — it usually turns on serial or part numbers too.

Model 767 series airplanes powered by Rolls-Royce RB211 series engines, line numbers 1 through 663 inclusive, certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously. To prevent fatigue cracking in primary strut structure and consequent reduced structural integrity of the strut, accomplish the following: Modifications (a) At the later of the times specified in paragraph (a)(1) or (a)(2) of this AD, modify the nacelle strut and wing structure on both the left and right sides of the airplane, in accordance with Boeing Service Bulletin 767-54-0082, dated October 28, 1999: (1) Prior to the accumulation of 37,500 total flight cycles, or within 20 years since the date of manufacture, whichever occurs first. Use of the optional threshold formula described in Figure 1 of the service bulletin is an acceptable alternative to the 20-year threshold, provided that the additional criteria specified in the service bulletin are met; or (2) Within 3,000 flight cycles after the effective date of this AD. (b) Prior to or concurrently with the accomplishment of the modification of the nacelle strut and wing structure required by paragraph (a) of this AD, as specified in paragraph 1.D., Table 2, “Prior or Concurrent Service Bulletins,” on page 3 of Boeing Service Bulletin 767-54-0082, dated October 28, 1999, accomplish the actions specified in the following service bulletins: Boeing Service Bulletin 767-29-0057, dated December 16, 1993; Boeing Service Bulletin 767-54-0059, dated July 28, 1994; Boeing Service Bulletin 767-54-0069, Revision 1, dated January 29, 1998; Boeing Service Bulletin 767-54-0083, dated September 17, 1998; Boeing Service Bulletin 767-54-0088, Revision 1, dated July 29, 1999; and Boeing Service Bulletin 767-57-0053, Revision 2, dated September 23, 1999.

However, inspections and rework accomplished in accordance with Boeing Service Bulletin 767-57-0053, dated June 27, 1996, or Revision 1, dated October 31, 1996, are acceptable for compliance with the applicable action required by paragraph (b) of this AD. Repair (c) If any damage to airplane structure is found during the accomplishment of any modification required by paragraph (a) or (b) of this AD, and the applicable service bulletin specifies to contact Boeing for appropriate action, then prior to further flight, repair in accordance with a method approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA. For a repair method to be approved by the Manager, Seattle ACO, as required by this paragraph, the Manager's approval letter must specifically reference this AD. Alternative Methods of Compliance (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle ACO. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. Special Flight Permits (e) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.
