NTSB narrative
The pilot reported that the airplane's canopy opened on the takeoff roll prior to liftoff. Noting that there was not enough remaining runway to land safely, he continued the climb to 1,000 feet where he attempted to close the canopy. He was able to partially lock the canopy, and returned to the pattern to make a precautionary landing. The pilot reported that while in the landing flare the canopy opened again, obscuring his forward view. A witness reported that the airplane bounced on touchdown, became airborne, and then touched down again on the runway. After touching down, the right wing dropped and the airplane veered to the right. The airplane then made a rapid 90-degree left turn and went up on its nose, resulting in substantial damage. The pilot reported that the accident could have been prevented had he used his pre-takeoff checklist and ensured that the canopy had been completely closed prior to takeoff. Both the pilot and a witness reported a quartering headwind with about a 15-knot crosswind.
Probable cause
The pilot's failure to follow the pre-takeoff checklist that resulted in the canopy opening during takeoff, which created a distraction, and his failure to maintain aircraft control during landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
