NTSB narrative
AT THE END OF THE FLIGHT, THE PILOT REPORTED THAT HE SELECTED THE GEAR DOWN AND HEARD THE GEAR EXTENDING. JUST PRIOR TO TOUCHDOWN, THE PILOT NOTED THAT THE GEAR SELECTOR WAS DOWN; HOWEVER, HE DID NOT HAVE A GREEN GEAR DOWN AND LOCKED INDICATION. THE AIRPLANE WAS LANDED WITH THE LANDING GEAR RETRACTED. DURING THE POST CRASH INSPECTION, IT WAS FOUND THAT THE GEAR SELECTOR SWITCH FUNCTIONED INTERMITTENTLY. IT WAS ALSO FOUND THAT THE GEAR WARNING HORN THAT IS CONNECTED TO THE THROTTLES WAS INOPERATIVE.
Probable cause
PROCEDURES/DIRECTIVES WERE NOT FOLLOWED AND PARTIAL FAILURE OF THE LANDING GEAR SELECTOR SWITCH. A FACTOR TO THE ACCIDENT WAS AN INOPERATIVE GEAR WARNING SYSTEM.

- 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.
