NTSB narrative
The pilot was conducting a personal flight with four passengers. A witness observed the airplane take off and climb slowly from the airport. A pilot flying in the vicinity observed the airplane maneuver erratically before the airplane impacted terrain in a near-vertical attitude. The airplane was destroyed by impact forces and a postimpact fire.
The wreckage was contained to a confined area in the field and the remains of the major airplane components were all accounted for. Extensive thermal damage to the airframe and engine limited the scope of the postaccident examination. The impact energy needed to drive the engine into the ground suggested that the engine was producing power at the time of the accident. A postaccident examination of the remaining airframe and engine components did not reveal any anomalies which would have precluded normal operation of the airplane.
Depending on the amount of fuel, baggage and equipment on board, and the location of the adult passenger, the center of gravity (CG) could have been within or aft of the recommended CG. Since fuel load and location of the passengers could not be determined or may have shifted during flight, it is not known if loading contributed to the accident.
The pilot was not operating with valid medical certification. His second-class medical certificate had expired several years prior to the accident and Federal Aviation Administration records did not indicate that he had obtained BasicMed medical certification. A pilot-rated passenger was seated in the right-front seat. Investigators were unable to determine who was manipulating the flight controls of the airplane at the time of the accident.
The circumstances of the accident are consistent with the pilot’s loss of control. However, the reason for the loss of control could not be determined with the available evidence.
Probable cause
The pilot's loss of control for reasons that could not be determined with the available evidence.

- 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.
