Compliance required as indicated.

To prevent possible loss of the vertical fin, accomplish the following: Within the next ten days after the effective date of this AD, unless previously accomplished, visually inspect the tail boom frame 28 on the left and right booms for cracks in accordance with paragraph 2C(1) of British Aerospace Service Bulletin Number 55/39 dated June 1981 or in a manner approved by the Chief, Seattle Area Aircraft Certification Office, FAA, Northwest Mountain Region.

A. If no cracks are found, reinspect at intervals not to exceed 75 flight hours after the initial inspection by visual and eddy current methods in accordance with paragraphs 2C(1) and 2C(2) of British Aerospace Service Bulletin Number 55/39 dated June 1981 or in a manner approved by the Chief, Seattle Area Aircraft Certification Office, FAA, Northwest Mountain Region.

C. If cracks are found, evaluate the damage in accordance with paragraph 2E of British Aerospace Service Bulletin Number 55/39 dated June 1981. If the airplane can continue to fly, reinspect in accordance with the inspection intervals contained in paragraph A and B of this ZD. If the cracks are such that the airplane cannot continue to fly after evaluation of the damage in accordance with paragraph 2E of the service bulletin, the modification as described in paragraph 2F of the service bulletin must be made prior to further flight.

Upon the accomplishment of the modification, no further AD inspections are required.
