Summary
Requires replacing certain part-numbered second-stage power turbine (PT2) blades before next flight. Prompted by a recent in-service report of a 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. P&WC is still investigating the root cause of the blade failures.
