To eliminate the possibility of the elevator forward override mechanism becoming jammed, accomplish the following, unless already accomplished:

A. Within the next 60 days after the effective date of this AD, remove and replace the elevator control forward override assembly cam with a revised cam in accordance with Boeing Service Bulletin 757-27-0057, Revision 1, dated October 17, 1985, or later FAA- approved revision.

B. 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 modifications required by this AD.

All persons affected by this proposal who have not already received the appropriate service document from the manufacturer may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124-2207. 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.
