## Discrepancy

MSS/HPN - AT 9,500 FEET APPROXIMATELY 15 MINUTES INTO THE FLIGHT, THE LEFT ENGINE RPM STARTED FLUCTUATING ABOUT 150 RPM.  ABOUT 5 MINUTES LATER THAT ENGINE FAILED COMPLETELY.  AFTER ATTEMPTING A RE-START AND CHECKING GAUGES (FUEL FLOW, 20 FEET MANIFOLD, PRESSURE) THE ENGINE WAS FEATHERED AND A PRECAUTIONARY LANDING WAS MADE AT COLUMBIA COUNTY.  IT APPEARS THERE WAS A CAMSHAFT FAILURE.
