NTSB narrative
THE CERTIFICATED PRIVATE PILOT WAS REPORTED OVERDUE WHILE RETURNING FROM A SHORT CROSS COUNTRY FLIGHT TO AN AIRPORT LOCATED IN AN AREA OF LITTLE GROUND ILLUMINATION DURING THE HOURS OF DARKNESS. THE SURROUNDING TERRAIN CONSISTED OF MOUNTAINS TO THE RIGHT AND A LAKE TO THE LEFT OF THE DIRECTION OF FLIGHT. THE AIRPLANE OVER-FLEW THE RURAL AIRPORT ON A MOONLESS NIGHT AND MADE A LEFT TURN TO ENTER THE DOWNWIND PORTION OF A VFR APPROACH. THE TERRAIN AND LIGHT CONDITIONS PRODUCED DARK AND FEATURELESS VISUAL CONDITIONS. THE AIRPLANE WAS LOCATED THE NEXT DAY AND HAD STRUCK TERRAIN 1/2 MILE FROM THE DESTINATION AIRPORT IN A HIGH SPEED DESCENDING LEFT TURN.
Probable cause
THE FAILURE OF THE PILOT TO MAINTAIN AIRCRAFT CONTROL DUE TO SPATIAL DISORIENTATION DURING A NIGHT APPROACH.

Source notes (4)
- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1991-05-06.
