Event Details
A pilot reported that while 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 final, the approach angle to the runway was steeper than normal, and the airplane was still high.
Pilot Report
The pilot stated that due to the steeper approach angle, he misjudged the landing flare. The airplane landed hard, bounced, and began to porpoise. As he attempted to abort the landing, the airplane veered to the right and landed in the dirt adjacent to the runway. Subsequently, the airplane nosed over.
Damage
The nose-over resulted in 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.
