NTSB Factual Report

The pilot initiated a takeoff and as the airplane became airborne, the canopy opened. The pilot attempted to close the canopy and lost control of the airplane. The airplane landed hard on the runway causing substantial damage to the airframe. The pilot stated he failed to secure the canopy before takeoff and there were no preaccident mechanical malfunctions or failures that would have precluded normal operations.

NTSB Probable Cause

The pilot's attempt to secure an open canopy during takeoff, which resulted in a loss of control and subsequent hard landing.
