The flight was the first flight of the experimental amateur-built Zenith CH750.
According to the pilot, he was landing at the airport in Xenia, Ohio, when the accident occurred.
He told investigators he was lined up with the runway center line, that his airspeed was 60 mph, and the tachometer registered 1,600 rpm, when he felt the right tire contact the runway.
He said, “In an instant the left wing came down and the left tire and axle were sheared off. The left wing contacted the runway and the plane skidded about 40 feet and came to a full stop.”
Post-accident examination of the airplane revealed that the left wing tip was bent up, the nose landing gear “U” channel was bent 90°, and the skin around the left wing strut and landing gear attachment points were buckled.
The pilot noted he used a higher landing airspeed since he had been told by other builders of that airplane that he needed to land with speed “so as not to get near the stall speed as this aircraft does have leading edge slats and this equates to a high lift wing.”
The pilot reported that the wind was calm, the altimeter setting was 30.12 inches, and the temperature was 55°F. The wind recorded at an airport eight miles north of the airport where the accident occurred was from 200° at 12 knots.
There were no reported pre-impact anomalies with the airplane.
Probable Cause: The pilot’s failure to maintain airplane control during landing, which resulted in the right tire contacting the runway first followed by the left wing.
