Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The loss of engine power due to the failure of the engine blower. A factor was the lack of suitable terrain at the pilot's disposal.

Analysis

An agricultural airplane on a rye grass seeding flight experienced a loss of engine power as the pilot started to bank the airplane to reverse direction at the top of the turn. The pilot was able to roll the wings level and drop the nose to maintain flying speed until just above the trees, where he stalled the airplane and settled into the trees. The power loss was attributed to the failure of the engine blower bearings.
