NTSB narrative
The night training flight was conducted using night vision goggles, and a crew change was conducted while helicopter continued to operate. The maneuvers conducted included hovering, straight-in and 180° autorotations to touchdown, hydraulics off flight, and stuck-pedal flight to touchdown. The flight instructor and the two pilots described the maneuvers as smooth and controlled with no hard landings. A post-flight inspection revealed substantial damage to the left vertical stabilizer, and “rub marks and scratches” on the underside of each main rotor blade consistent with main rotor contact. A main rotor strike of the vertical fin likely occurred during a hard landing at the termination of an autoration, but the investigation was unable to determine the specific training event during which the main rotor strike occurred.
Probable cause
A hard landing, which resulted in a main rotor strike of the left vertical stablizer.

- 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, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2023-11-16.
