Incident Summary
A pilot reported that after performing a run-up check, he took the runway for takeoff. The airplane rotated, lifted off, and was climbing normally. When the aircraft reached approximately 80 feet above the ground, the canopy suddenly opened. The pilot stated that the canopy moved to the full open position, and the airplane subsequently yawed 45 degrees to the right.
Pilot Actions
In response, the pilot lowered the airplane's nose, applied full left rudder, and reduced engine power to idle. He then switched hands on the control stick and, with his right hand, reached up and pulled the canopy closed. According to the pilot, his airspeed was just above the stall speed and the wings were level. The airplane was approximately 20 feet above the ground when it "pancaked perfectly flat to the side of the runway."
Post-Accident Examination
An examination of the airplane's canopy latching mechanism and other airplane systems revealed no anomalies. No mechanical or system malfunctions were identified that could have caused the canopy to open.
Probable Cause
No probable cause was stated in the source.
