NTSB narrative
The pilot was regaining night flying proficiency and was practicing a night autorotation landing from 3,000 feet without use of the aircraft's landing light. There was a full moon and the ground was visible. During the autorotation flare, he misjudged the aircraft's height above the surface, flared too high, and the helicopter dropped the last 4 or 5 feet. The aircraft landed hard with little energy in the main rotor and the rotor severed the tail boom. The pilot reported that he had no other night flying time in the previous 90 days, and that there were no mechanical malfunctions involved. He also said that the landing light was operational had he chosen to use it.
Probable cause
The pilot's inaccurate perception of altitude which resulted in an improper flare and subsequent hard landing, and non use of the landing light.

- 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. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1996-08-30.
