Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Canada Limited Model 206L-1, 206L-3, and 206L-4 helicopters with certain Air Comm Corporation (Air Comm) air conditioning systems installed. This proposed AD would require visually inspecting the drive ring spline teeth and the mating area spline teeth on the oil cooler blower shaft for signs of deformation and fretting and depending on the results of the inspection, removing certain parts from service. This proposed AD would also require reinstalling certain parts, applying torque, and aligning certain bolt holes. This proposed AD was prompted by reports of damage to the drive ring spline teeth and the mating spline teeth. The actions of this proposed AD are intended to address an unsafe condition on these products.
