The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Aerospatiale Model ATR42-200, -300, and -320 series airplanes. This action requires modification of the electrical wiring of the stick pusher/shaker test function to reinforce system protection. This amendment is prompted by a report of at least one occurrence when the stick pusher self-activated during flight. The actions specified in this AD are intended to prevent inadvertent activation of the stick pusher, which could cause reduced controllability of the airplane, especially during takeoff or landing.
