SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   88-15-07 BRITISH AEROSPACE: Amendment 39-5981. Applies to all British Aerospace (BAe) Model 146 series airplanes as listed in BAe 146 Service Bulletin 32-73, dated March 13, 1987, certificated in all categories. Compliance required as indicated, unless previously accomplished.

To prevent collapse of the main landing gear (MLG) due to defective main fittings, accomplish the following:

A. Prior to the accumulation of 12,000 landings or within the next 1,000 landings after the effective date of this AD, whichever occurs later, inspect the main fitting and barrel section of the main fitting in accordance with British Aerospace BAe 146 Service Bulletin 32-73, dated March 13, 1987. If defective parts are identified during the inspection, repair, prior to further flight, in accordance with Dowty Rotol Service Bulletin number 146-32-23.

NOTE: British Aerospace BAe Service Bulletin 32-73 references Dowty Rotol Service Bulletin 146-32-23 for specific procedures for identification, inspection, and repair of the affected MLG parts. The modification of MLG fittings in accordance with Dowty Rotol Service Bulletin 146-32-56 (as recommended in Dowty Rotol Service Bulletin 146-32-23) is not made mandatory by this airworthiness directive.

B. 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.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who may add any comments and then send it to the Manager, Standardization Branch, ANM-113.

C. 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 the modifications required by this AD.

All persons affected by this directive 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, 39-5981, becomes effective August 22, 1988.
