NTSB narrative
WITNESSES REPORTED HEARING THE EARLY MORNING TAKEOFF, FOLLOWED BY POPPING AND SPUTTERING NOISES. WHILE MANEUVERING BACK TO THE AIRFIELD, THE AIRPLANE STALLED, AND COLLIDED WITH THE GROUND AT A STEEP ANGLE. INSPECTION OF THE WRECKAGE REVEALED THAT THE GEAR AND FLAPS WERE DOWN, AND THE LEFT PROPELLER APPEARED TO BE FEATHERED. THE RIGHT ENGINE PROPELLER SHOWED EVIDENCE OF POWER AT IMPACT. DESPITE SIGNIFICANT POST-CRASH FIRE DAMAGE, NO EVIDENCE OF A MECHANICAL ENGINE FAILURE WAS FOUND. CONTINUITY WAS CONFIRMED THROUGHOUT THE FLIGHT CONTROL SYSTEM.
Probable cause
THE LOSS OF LEFT ENGINE POWER FOR UNDETERMINED REASONS, AND THE FAILURE OF THE PILOT TO MAINTAIN MINIMUM CONTROLLABLE AIRSPEED, WHICH RESULTED IN THE STALLING OF THE AIRPLANE.

- 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.
