| Confidence Rating: |  Accident investigation report completed and information captured |
The airplane was on a cross-country pipeline inspection flight which required the pilot to fly at a altitude 100 to 150 feet agl. The airplane was observed to start climbing to near vertical with a left turn and then went over the top, spinning to the ground. One witness reported seeing the airplane many times before, and she had observed it flying 90 degree knife edges and performing vertical pop-up turns. No preimpact engine or airframe anomalies, which might have affected the airplane's performance, were identified.
Probable Cause: The pilot's attempted aerobatic maneuver and the subsequent inadvertent stall/spin. A factor was his intentional low altitude flight.
