Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Airframe/component/system failure/malfunctionTakeoff - initial climb
Door,exterior crew - unlockedCause
Loss of control - in flightTakeoff - initial climb
Remedial action - not possiblePilot in command
In flight collision with terrain/waterDescent - uncontrolled

Analysis

The pilot stated the cockpit canopy opened during initial climb at about 12 feet AGL and that this disrupted the air flow sufficiently that the aircraft became uncontrollable. The aircraft settled back onto the runway with a hard touchdown and then departed the runway into the grass. The pilot stated that the canopy was properly closed and locked before the takeoff was started.
