NTSB narrative
THE PILOT OF THE NORTH AMERICAN NAVION HEARD A LOUD POP IN THE AREA OF THE NOSE GEAR WHEEL WELL WHEN HE LOWERED THE NOSE GEAR TO THE RUNWAY DURING A PLANNED FULL-STOP LANDING. AS THE NOSE OF THE AIRCRAFT BEGAN TO SETTLE, THE PILOT EXECUTED A GO-AROUND. THE PILOT OF ANOTHER AIRCRAFT INSPECTED THE GEAR WHILE INFLIGHT, AND REPORTED THAT IT WAS BENT OR COCKED TO THE SIDE. THE NAVION PILOT THEN CHOSE TO LAND WITH ALL GEAR IN THE UP POSITION. THE PILOT MADE A SUCCESSFUL TOUCHDOWN, BUT THE AIRCRAFT WAS DAMAGED BY THE GRINDING ACTION OF THE ASPHALT RUNWAY.
Probable cause
THE PARTIAL FAILURE OF THE NOSE GEAR TRUNNION. FACTORS INCLUDE THE PILOT'S DECISION TO LAND WITH THE GEAR IN THE UP POSITION.

- 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 1992-06-09.
