SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   83-20-02 BRITISH AEROSPACE: Amendment 39-4735. Applies to Model BAC 1-11 200 and 400 series airplanes, certificated in all categories. To prevent failure of the No. 1 left and right side fuselage mounted flap beam on aircraft that have not incorporated Modification No. PM5805, accomplish the following unless previously accomplished:

A. Inspect and repair or replace, as necessary, the forward and aft spigots of the No. 1 flap beam in accordance with paragraph 2, Accomplishment Instructions, of British Aerospace Alert Service Bulletin No. 53-A-PM5805, Issue 2, dated May 4, 1982, per the following schedule:

1. For aircraft which have accumulated 27,000 or more landings on the effective date of the AD, compliance is required prior to the accumulation of 30,000 landings, or within the next 1,000 landings, whichever occurs later.

2. For aircraft which have accumulated less than 27,000 landings on the effective date of the AD, compliance is required prior to the accumulation of 18,000 landings, or within the next 3,000 landings, whichever occurs later.

B. Repeat the actions of paragraph A., above, at intervals not to exceed 6,000 landings.

C. Incorporation of modification PM5805 terminates the repetitive inspection requirement of paragraph B., above.

D. For the purpose of this AD, and when approved by an FAA maintenance inspector, the number of landings may be computed by dividing each airplane's time in service by the operator's fleet average time from takeoff to landing for the aircraft type.

E. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, 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.

This amendment becomes effective November 3, 1983.
