NTSB narrative
THE PILOT STATED THAT WHEN HE RETRACTED THE LANDING GEAR AFTER TAKEOFF, HE DID NOT GET A 'NOSE GEAR UP' INDICATION. THE GEAR WAS CYCLED AND GROUND OBSERVERS REPORTED THAT THE NOSE GEAR APPEARED TO HAVE 'ROTATED OUT OF PROPER ORIENTATION.' THE NOSE GEAR COLLAPSED UPON TOUCHDOWN. THE CAUSE OF THE NOSE GEAR MALFUNCTION WAS NOT DETERMINED.
Probable cause
THE FAILURE OF THE NOSE GEAR, WHICH FAILED TO RETRACT WITH THE MAIN LANDING GEAR AFTER TAKEOFF; THE GEAR WAS OBSERVED TO BE MISALIGNED, AND COLLAPSED DURING THE AIRCRAFT'S TOUCHDOWN.

- 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.
