NTSB narrative
The pilot was flying on the first flight in the airplane since certification. Shortly after takeoff, he reported over a common airport frequency that the airplane had low engine oil pressure and that he was returning to the airport to land. Witnesses observed the airplane maneuver from the downwind leg to final approach for the intended runway by executing a 180-degree left turn. One witness observed the airplane's bank increase to about 90 degrees and descend out of sight. Another witness observed that the airplane was low and slow and appeared to stall. The witness stated that the left wing dropped and that the airplane went straight down.
Postaccident examination of the airframe, flight control components, and the engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. It is likely that, because this was the pilot's first flight in the airplane and he was distracted by the low oil pressure, he failed to maintain adequate airspeed while maneuvering, and the airplane subsequently stalled. The toxicology report indicated that the pilot was taking medication for several medical conditions; however, insufficient information was available to determine if the pilot's medical conditions contributed to the accident.
Probable cause
The pilot's failure to maintain adequate airspeed while maneuvering to final approach due to his distraction by the low engine oil pressure, which resulted in an aerodynamic stall.

- 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.
