Airworthiness Directives; British Aerospace (Jetstream) Model 4101 Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace (Jetstream) Model 4101 airplanes, that requires a functional check of the rudder pedals to ensure full and free movement at all rudder pedal positions, and modification of the forward rudder pedal boxes. The actions specified by this AD are intended to prevent restricted movement of the rudder pedals due to structural interference, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
