Airworthiness Directive · Amendment 39-10111 · Raytheon Aircraft Company Model 1900D Airplanes (Formerly Known as Beech Aircraft Corporation Model 1900D Airplanes)
Raytheon Aircraft Company Model 1900D Airplanes (Formerly Known as Beech Aircraft Corporation Model 1900D Airplanes)
Model 1900D airplanes (serial numbers UE-176 through UE-280, UE-282 and UE-284) certificated in any category, that have not had the propeller removed and re-installed since factory installation, or have not had the attaching bolts re- torqued.
This amendment adopts a new airworthiness directive (AD) that is applicable to Raytheon Aircraft Company (Raytheon) Model 1900D airplanes (formerly known as Beech Aircraft Corporation Model 1900D airplanes) that have not had the propeller removed and re-installed since factory installation. This action requires inspecting the propeller mounting bolts for the proper torque and replacing or re- torquing any propeller bolt with the wrong torque level. The manufacturer discovered some under-torqued propeller mounting bolts during factory installation of the propeller. The actions specified by this AD are intended to prevent fatigue cracking and failure of the propeller mounting bolts, which if not detected and corrected, could result in loss of the propeller.
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.
