NTSB narrative
WHILE CLIMBING DURING A DOWNWIND DEPARTURE, THE PILOT OF THE NAVION DECLARED AN EMERGENCY AND INITIATED A DESCENDING TURN BACK TOWARD THE AIRFIELD. AFTER THE TURN WAS INITIATED, WITNESSES NOTED AN INTENSE FIRE IN THE CABIN OF THE AIRCRAFT. SUBSEQUENTLY, THE AIRPLANE CRASHED IN A STEEP, LEFT WING LOW, NOSE DOWN ATTITUDE AND WAS DEMOLISHED BY IMPACT AND FIRE. THERE WAS EVIDENCE THAT THE FIRE AND SMOKE WERE SO INTENSE THAT THE PILOT WAS UNABLE TO MAINTAIN CONTROL OF THE AIRCRAFT. THE SPECIFIC SOURCE OF FIRE WAS NOT DETERMINED.
Probable cause

- 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.
