## The airworthiness directive

87-03-05 BRITISH AEROSPACE: Amendment 39-5516. Applies to Model BAe 125- 800A and -800B series airplanes, listed in British Aerospace Service Bulletin 53-59 (3031B), dated June 5, 1986, certificated in any category. Compliance is required prior to the accumulation of a total of 3,000 flight cycles, or within the next 90 days after the effective date of this AD, whichever occurs later. To prevent the possible rapid loss of cabin pressurization, accomplish the following, unless previously accomplished:

A. Modify the fuselage canopy upper rail in accordance with Section 2, "Accomplishment Instructions," of British Aerospace Service Bulletin 53-59-(3031B), dated June 5, 1986.

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.

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 modification 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 for Service Bulletins, 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 February 19, 1987.
