SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   85-14-03 BRITISH AEROSPACE: Amendment 39-5092. Applies to Model BAC 1-11 series 400 airplanes certificated in any category. Compliance is required as indicated. To prevent asymmetrical deployment of ground spoilers (lift dumpers) accomplish the following, unless previously accomplished within the last 1000 landings or one year, whichever occurred earlier:

A. Within the next 100 landings or 30 days after the effective date of this AD, whichever occurs first, and thereafter at intervals not to exceed 5,000 landings from the last inspection, inspect the ground spoiler mechanical locks for misalignment, and adjust if necessary, in accordance with the accomplishment instructions of British Aerospace BAC 1-11 Alert Service Bulletin 27-A-PM5890, dated December 21, 1983.

From the results of the inspection above:

1. If two or more mechanical locks out of the four per ground spoiler are found unserviceable, perform an operational check of the ground spoilers prior to further flight and thereafter at intervals not to exceed 600 landings or 150 days, whichever occurs earlier, until defective components are replaced in accordance with the accomplishment instructions of the service bulletin.

2. If one mechanical lock out of the four per ground spoiler is found unserviceable, perform an operational check of the ground spoilers prior to further flight and thereafter at intervals not to exceed 2,500 landings in accordance with the accomplishment instructions of the service bulletin until defective components are replaced.

3. If the mechanical lock system fails the operational check conducted in accordance with paragraphs A.1. or A.2., above, the locks must be repaired or the ground spoilers rendered inoperative in accordance with the accomplishment instructions of the service bulletin prior to further flight.

B. Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, 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 inspections and/or modifications required by this AD.

This amendment becomes effective August 15, 1985.
