93-23-02 JETSTREAM AIRCRAFT LIMITED: Amendment 39-8736. Docket 93-NM-180-AD.
Applicability: Model 4101 airplanes; as listed in Jetstream Aircraft Limited Alert Service Bulletin J41-A52-021, dated August 24, 1993; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent the inability of passengers to evacuate the airplane through the main entrance door in an emergency, accomplish the following:

(a) Within 30 days after the effective date of this AD, perform a detailed visual inspection to detect damage of the electrical loom in the main entrance door in accordance with Jetstream Aircraft Limited Alert Service Bulletin J41-A52-021, dated August 24, 1993.

(b) If any damage is found during the inspection required by paragraph (a) of this AD, prior to further flight: Replace the loom with a new loom; modify the electrical loom routing and support by re-routing the loom and support clear of the speedlock solenoid and the inner skin of the door; perform an operational test of the main entrance door warning system; and perform a functional test of the main entrance door, examining the clearance between the speedlock solenoid and the door inner skin to ensure that the electrical loom cannot become trapped between those parts; in accordance with Jetstream Aircraft Limited Alert Service Bulletin J41-A52-021, dated August 24, 1993.

(c) If no damage is found during the inspection required by paragraph (a) of this AD, prior to further flight, modify the electrical loom routing and support by re-routing the loom and support clear of the speedlock solenoid and the inner skin of the door; perform an operational test of the main entrance door warning system; and perform a functional test of the main entrance door, examining the clearance between the speedlock solenoid and the door inner skin to ensure that the electrical loom cannot become trapped between those parts; in accordance with Jetstream Aircraft Limited Alert Service Bulletin J41-A52-021, dated August 24, 1993.

(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, Standardization Branch, ANM-113, 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, Standardization Branch, ANM-113.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113.

(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.

(f) The inspection, replacement, modification, and tests shall be done in accordance with Jetstream Aircraft Limited Alert Service Bulletin J41-A52-021, dated August 24, 1993. 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. Copies may be obtained from Jetstream Aircraft, Inc., P.O. Box 16029, Dulles International Airport, Washington, DC 20041-6029.
