NTSB narrative
The flight was scheduled as recurrent training in helicopters; the foreign rated pilot was accompanied by a flight instructor, and an interpreter and observer who were seated in the back seats. After a series of maneuvers, the foreign pilot conducted a hovering autorotation, following directions from the flight instructor which were translated by the interpreter. During the autorotation, the helicopter yawed slightly right and settled to the ground. The instructor and observer noted that the landing did not feel that hard, but more like a firm or rough landing. The training flight continued with several other autorotations. During a post flight inspection of the helicopter, several wrinkles were found in the tail boom of the helicopter. Further examination of the helicopter revealed that the tail boom had sustained substantial damage.
Probable cause
The flight instructor's inadequate supervision during a practice autorotation. Contributing to the accident was the pilot's hard landing during a practice autorotation.

- 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, coordinates. 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.
