Applicability*9

BAe Model ATP airplanes, constructor's numbers 2002 through 2063 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.

Compliance

Required as indicated, unless accomplished previously. To prevent loss of function of the power control levers on the console, and subsequent loss of normal control of engine power due to failure of the engine power cables, accomplish the following: (a) Perform a detailed visual inspection and tests for damage of the engine power cables, in accordance with Jetstream Service Bulletin ATP-76-16, dated October 14, 1994, [[Page 13778]] at the earlier of the times specified in paragraphs (a)(1) and (a)(2) of this AD. Thereafter repeat this inspection and tests at intervals not to exceed 1,000 landings. (1) Prior to the accumulation of 1,000 total landings on the engine power cable, or within 200 landings after the effective date of this AD, whichever occurs later. (2) Within 75 days after the effective date of this AD. (b) If any damaged engine power cable is found, prior to further flight, replace the damaged engine power cable with a new cable in accordance with Jetstream Service Bulletin ATP-76-16, dated October 14, 1994. Except as provided by paragraph (c) of this AD, repeat the inspection and tests required by paragraph (a) of this AD thereafter at intervals not to exceed 1,000 landings. (c) Modification of the engine power control cable pulley assembly in accordance with British Aerospace Service Bulletin ATP- 76-18, dated June 21, 1995, allows the interval for accomplishment of the repetitive inspection and tests required by paragraph (a) of this AD to be increased to 5,000 landings. (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, International Branch, ANM-116, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. (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. (f) The inspection, tests, and replacement shall be done in accordance with Jetstream Service Bulletin ATP-76-16, dated October 14, 1994. The modification, if accomplished, shall be done in accordance with Jetstream Service Bulletin ATP-76-18, dated June 21, 1995. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
