The NTSB's narrative final · quoted from the NTSB record
The airplane nosed over following a loss of engine power during an aerial application swath run. The pilot reported that as his load of fertilizer became lighter during the run, he reduced power. The pilot then attempted to add power at which time the engine was unresponsive. He reported the airplane immediately lost altitude, impacted the ground, and nosed over. A post accident inspection of the airplane failed to reveal any mechanical failure/malfunction which would have resulted in the loss of engine power.
