Airworthiness Directive · Amendment 39-11008 · Raytheon Aircraft Company Models B300 and B300C Airplanes
Raytheon Aircraft Company Models B300 and B300C Airplanes
The following models and serial number (S/N) airplanes, certificated in any category: Models Serial numbers B300........................................... FL-1 through FL-23, FL-25 through FL134, FL-136, and FL-137. B300C.......................................... FM-1 through FM-9, and FN-1.
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Models B300 and B300C airplanes (commonly referred to as Beech Models B300 and B300C airplanes). This AD requires modifying the elevator trim tab actuators by incorporating a new elevator trim tab actuator assembly kit, replacing the elevator trim tab pushrod assembly, or modifying the elevator spar opening, whichever is applicable. Reports from operators of ice forming on the elevator trim tab actuators and jamming the trim tab control prompted this action. The actions specified by this AD are intended to prevent jamming of the elevator trim tab actuator caused by ice formations, which could result in loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
