NTSB narrative
The pilot was landing his experimental, amateur-built airplane at a private airport when the airplane impacted terrain in a nose-down, near-vertical attitude short of the runway.
A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. No significant tree impacts were observed on the airframe. Based on the available information, it is likely that the pilot exceeded the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall and loss of control.
At the pilot’s request, numerous design changes were incorporated into the wings, ailerons, and flaps of the accident airplane. The manufacturer of the kit and the designer of the flaps stated that they told the pilot and builder that the design changes were not recommended; however, the kit was built to the pilot’s specifications. It is likely that the design changes affected the stall characteristic of the airplane; however, the role those changes played in the accident sequence could not be determined.
Probable cause
The pilot's exceedance of the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall and loss of control.

- 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: local date, investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2021-10-24.
