SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   86-14-09 BRITISH AEROSPACE AVIATION GROUP: Amendment 39-5348. Applies to all Model BAe HS 748 airplanes on which Modification 6909 has not been incorporated, certificated in any category.

Compliance is required within the next 500 flight hours time-in-service after the effective date of this AD, unless accomplished within the last 500 flight hours time-in-service, and thereafter at intervals not to exceed 1000 flight hours time-in-service. To prevent the loss of autofeather capability, accomplish the following:

A. Inspect the microswitch rocker arm assemblies in accordance with BAe Service Bulletin 76/15, Revision 3, dated November 1983. Replace any cracked rocker arm assemblies prior to further flight.

B. The installation of modified rocker arm assemblies, in accordance with BAe Service Bulletin 76/15, Revision 3, dated November 1983, terminates the requirement for the inspection called for in paragraph A., above.

C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.

All persons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to British Aerospace, Inc., Librarian, Box 17414, Dulles International Airport, Washington, D.C. 20041. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This amendment becomes effective August 4, 1986.
