NTSB narrative
DURING CRUISE, THE PLT ATTEMPTED TO SWITCH FUEL TANKS AND THE FUEL SELECTOR VALVE BECAME STUCK IN THE 'OFF' POSITION. A SUCCESSFUL GEAR-UP FORCED LDG WAS MADE IN A FIELD. AN EXAM OF THE VALVE CONFIRMED THAT IT WAS STUCK DUE TO CORROSION AND RUST, THE OPERATOR'S MECHANIC STATED THAT PRIOR TO THEIR RECENT ACQUISITION OF THE ACFT, IT HAD REMAINED INACTIVE AND OUTDOORS FOR A LONG PERIOD OF TIME. DURING THE RECENT ANNUAL INSP, HE STATED THAT THE FUEL CAP SEALS HAD DETERIORATED AND HAD TO BE REPLACED AND THAT WATER HAD BEEN FOUND IN THE FUEL TANKS.

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 1986-08-08.
- API snapshot SHA-256: 58e664f74c2b34328ed065bad4575e6eec44fd1dd922da598ecdb9f8c27b0be1; retrieved 2026-09-18T19:56:43.830Z.
