## Summary

We propose to adopt a new airworthiness directive (AD) for certain serial number Pratt & Whitney Canada Corporation (P&WC) model PW150A turboprop engines. This proposed AD was prompted by reports of damage to a high-pressure fuel line, which could result in a high- pressure fuel leak into the engine nacelle. This proposed AD would require rerouting of the igniter cables and installation of new support brackets. We are proposing this AD to prevent high-pressure fuel leaks, which could cause engine fire and damage to the engine and the airplane.
