NTSB narrative
The check pilot reported that, the pilot being evaluated was performing a simulated critical engine failure approach to a local airport. During the visual approach, everything seemed normal until touchdown when both pilots realized that the landing gear had not been extended. The airplane slid to a stop on the runway substantially damaging the lower fuselage. The check pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to extend the landing gear during landing and the check pilot’s inadequate supervision.

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: investigation status, cause areas. 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.
