Airworthiness Directives; Israel Aircraft Industries, Ltd., Model Astra SPX and 1125 Westwind Astra Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Israel Aircraft Industries, Ltd., Model Astra SPX and 1125 Westwind Astra series airplanes, that requires a one-time inspection of the position of the aileron autopilot servo and attachment arm; follow-on actions; and corrective actions, if necessary; and installation of a stopper angle on the servo bracket. This action is necessary to prevent the control link of the aileron autopilot servo from being driven overcenter, which could result in roll oscillations when the autopilot is engaged. This action is intended to address the identified unsafe condition.
