NTSB narrative
The commercial pilot reported that the flight was concluding at the end of his 17-hour duty day. He stated that he did not confirm a safe landing gear indication before landing and that the airplane subsequently landed with the landing gear retracted, which resulted in substantial damage. The pilot also stated that fatigue and self-induced distractions contributed to the accident, and that there were no mechanical anomalies with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to properly configure the airplane for landing. Contributing to the accident were the pilot’s fatigue and self-induced distractions.

- 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.
