Engine Indicating - Incorrect Engine Torque Indication

Airworthiness Directive CF-2015-01R2 is issued by Transport Canada concerning Pratt & Whitney Canada PT6B-37A engines installed on AW119MKII helicopters. The directive addresses incorrect engine torque indication caused by axial migration of bearings in the engine torque sensing gear, which can lead to undetected over-torque conditions. This revision updates compliance requirements to include an operating hours limit for bearing replacement.
