## Discrepancy

(CAN) THE PILOT REPORTED SHORTLY AFTER TAKEOFF THE RT ENGINE LOST OIL PRESSURE, ENGINE WAS SELECTED TO FEATHER AND SHUTDOWN, BUT PROPELLER FAILED TO FEATHER. A SUBSEQUENT INSPECTION OF THE RT ENGINE REVEALED THE FOLLOWING: OIL SUPPLY LINE FITTING AN8336 IN THE TURBOCHARGER WASTE GATE CONTROLLER WAS FOUND SEPARATED FROM THE WASTE GATE CONTROLLER RESULTING IN LOSS OF ENGINE OIL. THE THREADS IN THE WASTE GATE CONTROLLER WERE FOUND STRIPPED, THE PROPELLER AND PROPELLER GOVERNOR WERE REMOVED FOR INSPECTION BY CANADIAN PROPELLER, BUT NO FAULT WAS FOUND.
