## Discrepancy

DURING A TRAINING FLIGHT, WHEN SIMULATING THE V1 CUT THE LEFT PROPELLER TRIED TO GO INTO AUTOFEATHER AND THE ENGINE SURGED. NO SUBSEQUENT POWER SETTINGS AFFECTED THE PROBLEM SO THE LEFT ENGINE WAS SHUT DOWN, AN EMERGENCY WAS DECLARED AND AN UNEVENTFUL LANDING WAS MADE. MAINTENANCE SUBSEQUENTLY REPLACED THE PROPELLER GOVERNOR.
