REGULATORY TEXT:  
90-08-04 BRITISH AEROSPACE: Amendment 39-6560. Docket No. 89-NM-259-AD.
Applicability: Certain Model BAC 1-11 200 and 400 series airplanes, as listed in British Aerospace Service Bulletin 52-A-PM3682, Issue 1, dated August 30, 1968, certificated in any category.

Compliance: Required within 90 days after the effective date of this AD, unless previously accomplished.

To prevent fatigue damage to the service door and subsequent decompression of the airplane, accomplish the following:

A. Check the serial number plate located on the rear edge of the service door to determine if the service door part number and serial number correspond to the part number and serial number identified on page 1 of British Aerospace Service Bulletin 52-A-PM3682, Issue 1, dated August 30, 1968,

1. If the service door part number and serial number do not correspond with those in the service bulletin, no further action is required.

2. If the service door part number and serial number correspond with those in the service bulletin, perform an inspection using a micrometer or other suitably accurate instrument, taking three measurements on the lip of the flange of the forward side member to determine the thickness of the material, in accordance with the service bulletin.

a. If the measurement of the forward side member is 0.031 inches or more, no further action is required.

b. If the measurement of the forward side member is less than 0.031 inches, rework the service door forward side member, prior to further flight, in accordance with the service bulletin.

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 will either concur or comment 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 in order to comply with the requirements of 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, PLC, 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, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.

This amendment (39-6560, AD 90-08-04) becomes effective on May 4, 1990.
