NTSB narrative
The pilot reported that during a touch-and-go he touched down successfully and “normalized” the airplane for takeoff. He said that before breaking ground the gear inadvertently raised. An on-scene examination of the wreckage revealed that the landing gear handle was located in the "up" position. The airplane was raised and the landing gear lowered when electrical power was turned on in the airplane and the landing gear handle was placed in the "down" position. No mechanical anomalies were detected with the landing gear system that would have precluded normal operation. The airplane's takeoff checklist states, "Landing Gear - RETRACT (when positive rate-of-climb is established)."
Probable cause
The pilot's retraction of the landing gear prior to establishing a positive climb rate.

Source notes (4)
- 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.
