SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   87-25-06 BRITISH AEROSPACE: Amendment 39-5788. Applies to all Model H.S. 748 series airplanes as listed in BAe Service Bulletin 78/9, Revision 1, dated September 1985, certificated in any category. Compliance required as indicated, unless previously accomplished.

To prevent inflight loss of the jet pipe or restricted fuel drainage through the jet pipe retention assemblies, with resultant fire or heat damage to the nacelle and wing, accomplish the following:

A. Within the next 60 days after the effective date of this AD, perform an inspection to ensure correct installation of the three retaining plate assemblies, which secure the jet pipe inside the jet pipe manifold, in accordance with British Aerospace Service Bulletin 78/9, Revision 1, dated September 1985. Any discrepancies found must be corrected prior to further flight.

B. Repeat the inspection required by paragraph A. above, any time the jet pipe is replaced.

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 proposal who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to British Aerospace, Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or at the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This Amendment becomes effective January 19, 1988.
