| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he had just loaded 1,500 pounds of dry fertilizer for the next aerial application run. During the takeoff ground roll, approaching the departure end of the runway, the pilot noted that the airspeed was still too low for liftoff. He opted to dump the load and pull up to try and fly in ground effect. The airplane lifted off, but it settled in a nose high attitude into a field of tall wheat. The airplane decelerated and came to rest inverted. After the airplane was removed, the engine was inspected. During the inspection, a crack on the head of the number eight cylinder was found between the intake and exhaust valves. A weight and balance calculation showed the airplane was approximately 540 pounds over its maximum certified gross weight.
Probable Cause: a cracked cylinder head, which resulted in partial loss of engine power during takeoff. Factors relating to the accident were: the pilot allowed the gross weight of the airplane to be exceeded, and tall wheat (crop) in the emergency landing area.
