## Discrepancy

WHILE INSTRUCTOR PILOT PERFORMED EMERGENCY PROCEDURE TRAINING, SHUT DOWN AND SECURED THE LEFT ENGINE. UPON ATTEMPTING TO RESTART THE ENGINE, THE LEFT PROPELLER WOULD NOT UN-FEATHER. LANDED WITHOUT INCIDENT. MAINTENANCE CREWS DISCOVERED THE LEFT PROPELLER UNFEATHERING ACCUMULATOR WAS DEFECTIVE AND HAD IT OVERHAULED. OIL WAS FOUND IN THE ACCUMULATOR.
