Transport Canada issued emergency airworthiness directive (AD) CF-2024-05 today covering a large number of Pratt & Whitney Canada (P&WC) PT6 turbine engines. The AD requires compliance by removal of affected PT2 (power turbine) blades before further flight. 

According to the AD, “There has been one recent in-service report of PT2 blade failure on a PT6A-67 engine. In addition, there have been two other events of PT2 blade failures during testing at the manufacturer’s facility. The blade failures in all cases were contained.”
