## Analysis

THE PLT STATED THE ACFT WAS COVERED WITH ICE BUT HE REMOVED THE MAJORITY OF IT BEFORE TAKING OFF. THE ACFT CONTAINED A 200 GAL LOAD OF FUEL IN THE HOPPER. THE PLT STATED THE ACFT ACCELERATED SLOWER THAN NORMAL AND THE TAKEOFF GROUND RUN WAS LONG. HE STATED THAT ONCE AIRBORNE THE ACFT WOULD NOT CLIMB. THE ACFT CONTACTED SEVERAL SMALL TREES THEN CRASHED IN A CLEARING IN A WOODED AREA. A THIN LAYER OF ICE WAS FOUND ON THE LEADING EDGES OF BOTH WINGS AND ON THE HORIZONTAL STABILIZER AFTER THE ACCIDENT.
