NTSB narrative
A WITNESS ON THE GROUND WATCHED THE AIRPLANE FLY THE LANDING PATTERN FOR LANDING AND AT NO TIME DID HE SEE THE LANDING GEAR EXTEND. HE WATCHED THE AIRPLANE UNTIL IT PASSED BELOW THE TREE LINE. TESTING OF THE HYDRO-MECHANICAL AND ELECTRICAL SYSTEMS DID NOT REVEAL ANY PROBLEM. THE PILOT-IN-COMMAND STATED HE PLACED THE LANDING GEAR SWITCH IN THE DOWN POSITION AND SAW THREE GREEN INDICATOR LIGHTS, HOWEVER, HE DID NOT CONFIRM THE LANDING GEAR POSITION BY VIEWING THE NOSE GEAR IN THE MIRROR LOCATED ON THE SIDE OF THE ENGINE NACELLE. THE PASSENGER, A PILOT, STATED THAT AFTER LANDING HE HEARD A WARNING HORN SOUNDING IN THE COCKPIT.

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 1986-06-10.
