Airworthiness Directives; Cessna Model 750 Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Cessna Model 750 airplanes. This action requires repetitive lubrication of the aileron feel cartridge assembly shaft. This action also requires replacement of the roll feel and centering bungee assembly with an improved assembly, which constitutes terminating action for the repetitive lubrication. This amendment is prompted by reports of partial to full jamming of the aileron control circuit during flight of the airplane. The actions specified in this AD are intended to prevent the possibility of accumulation of ice on the aileron feel cartridge assembly shaft, which could result in jamming of the aileron control circuit, and consequent reduced controllability of the airplane.
