Analysis

The number 1 (left) engine failed during the takeoff from runway 35. It was reported that the aircraft yawed sharply left and climbed to between 50 and 100 feet AGL before it began losing alt. The aircraft struck the ground and continued to move forward on the ground several hundred feet until it struck the airport perimeter fence. The aircraft came to rest 1,600 feet west of the runway, on a heading of 290 degrees. A post-crash fire destroyed the cargo area of the aircraft. Examination of the no. 1 engine revealed a compressor turbine blade airfoil separation. Disassembly of the propeller on the no. 1 engine indicated that the propeller had autofeathered normally after the engine failed. The captain reportedly made the takeoff.
