REGULATORY TEXT:   87-22-05 BRITISH AEROSPACE: Amendment 39-5751. Applies to all Model H.S. 748 series airplanes with a large freight door, certificated in any category. Compliance required within the next 90 days after the effective date of this AD, unless previously accomplished.

To prevent inadvertent opening of the freight door in flight, accomplish the following:

A. Inspect the large freight door shoot bolt lever, barometric (pressure lock) lever, bellows assembly, dry air cartridge and microswitches for damage, distortion and/or wear in accordance with British Aerospace Service Bulletin 52/129, dated May 1986. If any damage, distortion and/or wear is discovered as a result of the inspection required by this paragraph, prior to further flight, adjust, repair, or replace the affected components, in accordance with British Aerospace Service Bulletin 52/129, dated May 1986.

B. Install a placard to indicate that the aircraft must be depressurized before opening its large freight door, in accordance with British Aerospace Service Bulletin 11/7, dated December 1, 1986.

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 information 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. This information 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 November 13, 1987.
