The pilot said that he did his run-up check and took the runway for takeoff. The airplane rotated, took off, and was climbing when approximately 80 feet above the ground, the canopy opened. The pilot said the canopy went to the full open position and the airplane subsequently yawed 45 degrees right. The pilot lowered the airplane's nose, applied full left rudder, and reduced the engine power to idle. The pilot said he then switched hands on the control stick and with his right hand, reached up and pulled the canopy closed. He said his airspeed was just above the stall speed and his wings were level. The airplane was approximately 20 feet above the ground when it "pancaked perfectly flat to the side of the runway." An examination of the airplane canopy latching mechanism and other airplane systems revealed no anomalies.

Probable Cause: The pilot's inadequate preparation prior to takeoff, and his failure to maintain control of the airplane resulting in a stall and subsequent crash. Factors contributing to the accident were the unsecured canopy latch, the pilot's diverted attention, and the stall mush.
