## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Fokker Model F28 Mark 1000, 2000, 3000, and 4000 series airplanes, and Model F28 Mark 0100 series airplanes. This proposal would require repetitive pre-load adjustment of the main landing gear (MLG) downlock-actuator. This proposal is prompted by reports that upon landing, the MLG had collapsed, as a result of the lock toggle-links being pulled out of the over-center position by the downlock-actuator due to the relative movement of the upper and lower side-stay members. The actions specified by the proposed AD are intended to prevent collapse of the MLG, which could adversely affect the controllability of the airplane during landing. DATES: Comments must be received by November 27, 1995.
