EASA AD CF-2020-13
Engine — Manual Calculation of Cycle Count for the Impeller and High Pressure Compressor Rotor
The Canadian Airworthiness Directive CF-2020-13 mandates manual calculation of cycle counts for the impeller and high pressure compressor rotor on Pratt & Whitney Canada PW210A and PW210S engines. This directive addresses inaccuracies in the Automated Damage Tracking System cycle counts to ensure these life-limited components are not operated beyond their safe limits. It applies to helicopter engines and aims to prevent potential uncontained failures that could lead to loss of control.
