Aircraft involved

Probable cause & findings

The pilot's improper flare, which resulted in a loss of aircraft control and hard landing.

Factual narrative

The pilot reported that during approach to land he flared too high. The airplane subsequently landed hard, which collapsed the left main landing gear and nose gear, and substantially damaged the left wing. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that during approach to land he flared too high.
