Aircraft involved

Probable cause & findings

The pilot’s failure to maintain an adequate airspeed during landing, which resulted in an aerodynamic stall.

Factual narrative

The pilot reported that after an uneventful cross-country flight, he returned to the airport to land with a 5 to 7 knot headwind down the runway. A witness stated to the Federal Aviation Administration (FAA) inspector that during the landing flare, at a height of approximately 5 feet, the pilot appeared to be at "a very high angle of attack". Subsequently, the airplane appeared to stall and land hard on the runway, substantially damaging both wings. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal flight.
