Plain English Summary

2/10 complexity

This CASA Airworthiness Directive mandates that owners, operators and maintainers of Pratt & Whitney Canada PT6A-6, -6A and -6B engines (S/N earlier than PC‑E20117) re-route the governor air pressure line per the manufacturer’s Service Bulletins. Compliance is required before installing any engine after its next reconditioning completed after 15 April 1966. The change prevents potential engine failure or loss of power from the original line routing.
