## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Fokker Model F.28 series airplanes. This proposal would require replacing the main landing gear (MLG) torque link dampers with modified and reidentified dampers. This action is necessary to prevent degradation of the dampers, which could result in MLG high amplitude oscillation in a lateral torsional mode, and consequent MLG damage or separation of the MLG from the airplane. This action is intended to address the identified unsafe condition.
