Plain English Summary

3/10 complexity

This AD applies to certain Gates Learjet 35/36 aeroplanes (specified by serial number) and mandates a one-time modification: replace existing flap sector mounting brackets with steel brackets per Gates Learjet Service Bulletin AMK 86‑4, deleting the prior repetitive inspection requirement. Unless already done, the work must be completed within 100 hours TIS or at the next maintenance release after 31 Jan 1987. Affected owners/operators must fund and arrange the modification, trading recurring inspections for a single corrective upgrade to address bracket cracking.
