NTSB narrative
The airplane was climbing through about 50 to 75 feet above ground level when it suddenly rolled left. The pilot tried to counteract the roll, but the airplane was unresponsive to control inputs. The sudden roll followed by a lack of control authority was consistent with an aerodynamic stall as the airplane transitioned from the aerodynamic effects of flight near the ground. A stall progression near the ailerons would have affected control authority. A postaccident examination of the flight control system revealed no malfunctions or failures that would have precluded normal operation. It is likely that the pilot climbed too steeply after takeoff without attaining the proper airspeed.
Probable cause
The pilot's failure to attain a proper pitch attitude and airspeed during initial climb, which resulted in an aerodynamic stall.

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.
