NTSB narrative
THE PILOT OF THE MOONEY M20J, N5810C, WAS DELIVERING HIS AIRPLANE TO THE BLUE ASH AIRPORT, OHIO FOR MINOR REPAIRS, WHEN HE CRASHED IN A WOODED AREA. HE HAD CALLED THE AIRPORT FOR LANDING INFORMATION MINUTES BEFORE THE ACCIDENT. AN FAA INSPECTOR SAID, 'I WOULD ESTIMATE THE ALTITUDE TO BE BETWEEN 200 AND 300 FEET ABOVE THE GROUND...THE AIRCRAFT WAS IN A NOSE HIGH ATTITUDE, THEN WENT INTO A SPIN...I THEN SAW THE AIRCRAFT HAD CRASHED.' THE LOCATION OF THE ACCIDENT WOULD HAVE BEEN A CLOSE BASE LEG FOR A VFR LANDING PATTERN. THE PILOT'S FLIGHT LOG SHOWED 3 FLIGHTS IN 1989, 2 FLIGHTS IN 1990, AND 1 FLIGHT IN 1991, ALL IN THE MOONEY M20J.
Probable cause
THE FAILURE OF THE PILOT TO MAINTAIN PROPER ALTITUDE AND AIRSPEED DURING A LANDING APPROACH, WHICH RESULTED IN A STALL AND SPIN AT TOO LOW AN ALTITUDE TO RECOVER. A FACTOR RELATED TO THE ACCIDENT WAS THE LACK OF RECENT FLIGHT EXPERIENCE BY THE PILOT.

- 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.
