REGULATORY TEXT:   86-11-02 BRITISH AEROSPACE: Amendment 39-5323. Applies to Model BAC 1-11 200 and 400 series airplanes, certificated in any category. To detect overspeeding of the cold air unit, accomplish the following within the next 120 days after the effective date of the AD, or prior to reaching the threshold indicated in each paragraph below, whichever is the later, unless already accomplished:

A. Prior to the accumulation of 10,000 flight hours or 8 years in service, whichever is the earlier, and thereafter at intervals not to exceed 3,000 flight hours or 14 months, whichever occurs first, perform a functional test of the cold air unit overheat protection circuits in accordance with paragraph 2.1 of the accomplishment instructions of British Aerospace BAC 1-11 Alert Service Bulletin 21-A-PM5863, Revision 2, dated June 12, 1984. If found faulty, the overheat protection circuits must be repaired before further flight.

B. For aircraft not incorporating Graviner 156D overheat detectors, prior to 300 flight hours after the effective date of this AD, perform a workshop calibration and functional test of the overheat detectors; thereafter, repeat this test at intervals not to exceed 3,000 flight hours or 14 months, whichever occurs first.

C. For aircraft incorporating Graviner 156D overheat detectors which have accumulated 7,000 flight hours or 4 years since new or from last calibration, perform a workshop calibration and functional test of the overheat detectors within the next 3,000 flight hours or fourteen (14) months, whichever is the earlier; thereafter, repeat this test at intervals not to exceed 10,000 flight hours or 6 years, whichever occurs first.

D. Overheat detectors that do not pass the tests of paragraphs B. or C., above, must be replaced before further flight.

E. 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.

F. 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 document from the manufacturer may obtain copies upon request to British Aerospace, Inc., 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 the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.
