Full official abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that currently requires, among other things, replacing certain yaw damper servos in the autopilot system, or rendering the servo inoperative. The actions specified by that AD are intended to prevent overheat failure of the Flight Control Computer (FCC), which could result in smoke in the flight deck that could inhibit the ability of the flightcrew to safely operate and land the airplane. This new amendment requires installation of circuit breakers on the avionics relay panel, which, when accomplished, constitutes terminating action for the previous requirements of the AD.
