Primary finding

Probable cause

The pilot’s improper flare and inadequate recovery from a bounced landing.

Investigator assessment

Analysis narrative

The pilot reported that upon entering the airport traffic pattern, he remained at a higher altitude than normal on the downwind and base legs due to helicopter traffic. Upon turning onto the final leg, the approach angle to the runway was steeper than normal and the airplane was still high. He stated that due to the steeper approach angle, he misjudged the landing flare; the airplane landed hard, bounced, and began to porpoise. As the pilot attempted to abort the landing, the airplane veered to the right and landed in the dirt adjacent to the runway where the airplane nosed over and sustained structural damage to both wings, the vertical stabilizer, and the rudder. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
