While conducting aerial agricultural spraying, the airplane was in a turn when the pilot heard a loud squeal, the engine lost power, and the pilot prepared for a forced landing to a cornfield. During the landing, the airplane nosed-over and sustained substantial damage to the wings. Examination of the radial engine revealed the supercharger bearings failed and were ingested into the engine case. The exact cause of the supercharger failure could not be determined. The engine had accumulated 765 hours since major overhaul as of its most recent annual inspection, about 5 months prior to the accident. The recommended time to overhaul for the engine was 1,200 hours.
Probable Cause: The loss of engine power due to the failure of the supercharger bearings.
