Probable cause
The erosion of the compressor impeller and the unsecured fuel control unit resulted in the loss of engine power during the initial climb.

Read the full NTSB narrative
According to the pilot, he was conducting agricultural operations and had dispensed approximately 13 loads of agricultural products. While preparing for another takeoff, the pilot noticed that the engine was slow to spool up to 100%. During climb-out the pilot noticed that he did not have enough power to maintain the climb. The pilot pushed the throttle full forward, dumped his load, and he could not arrest his descent. The airplane collided with trees as the pilot executed a forced landing. Examination of the engine assembly disclosed that the first stage compressor wheel displayed evidence of erosion. There was fresh dirt and debris in the first stage compressor assembly. Several stator vanes exhibited pre-impact bending associated with erosion. Further examination of the engine assembly disclosed that the fuel control unit rear support bracket bolt was not installed on the fuel control unit. The engine post-accident examination disclosed that the fuel control unit was displaced approximately 1/4 inch from the normally installed position. Examination of the fuel control unit showed chaffing on the pump flange.
