Models named: 3101, 3201. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

Jetstream Model 3101 airplanes, all serial numbers, and Jetstream Model 3201 airplanes, serial numbers 790 through 950, 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 use the authority provided in paragraph (d) of this AD to request approval from the FAA. This approval may address either no action, if the current configuration eliminates the unsafe condition, or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any airplane from the applicability of this AD.

Compliance

Required within the next 200 hours time-in-service after the effective date of this AD, unless already accomplished. To prevent failure of a diode in the central annunciator panel test button circuit, which could result in inadvertent engine shutdown while in flight if the central annunciator panel test button is pressed, accomplish the following: (a) Modify the central annunciator panel test button circuit (Amendment JA 911045) by removing diodes from the engine stop circuit and configuring a minor wiring change in accordance with PART 2 of the ACCOMPLISHMENT INSTRUCTIONS section of Jetstream Alert Service Bulletin 80-A-JA 911045, Revision 1, dated November 1, 1991. (b) As noted in Jetstream Alert Service Bulletin 80-A-JA 911045, Revision 1, dated November 1, 1991, terminals may be linked using 22 AWA cable and terminal tags, provided the following is accomplished: (1) For airplanes without roof panel plug breaks, identify the cables as WQ69 and WQ70. (2) For airplanes with roof panel plug breaks, identify the cables as WQ71 and WQ72. (c) 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. (d) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Brussels Aircraft Certification Office (ACO), Europe, Africa, Middle East office, FAA, c/o American Embassy, B-1000 Brussels, Belgium. The request should be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Brussels ACO. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Brussels ACO. (e) The modification required by this AD shall be done in accordance with Jetstream Alert Service Bulletin 80-A-JA 911045, Revision 1, dated November 1, 1991. 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.
