Airworthiness Directives; Fokker Model F-28 Mark 0100 Series Airplanes

Riepilogo

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F-28 Mark 0100 series airplanes, that requires the installation of modified Flight Warning Computers and Flight Augmentation Computers. This amendment is prompted by reports of nuisance yaw-damper fault warnings and undetected horizontal trim motion, and the development of improved computers that eliminate these problems. The actions specified by this AD are intended to prevent nuisance warnings in the cockpit and undetected trim motion, both of which could compromise the safe takeoff of the airplane.
