NTSB narrative
While demonstrating a 180 degree autorotation, the helicopter encountered a downdraft resulting in an unexpected loss of altitude. The flight instructor elected not to roll power and decided to continue the autorotation to the ground. The pilot was unable to arrest the descent rate. The helicopter touched down level, bounced, and came to rest in the upright position. The flight instructor and private pilot were able to exit the helicopter normally.
Probable cause
The pilot's failure to compensate for the excessive rate of descent on final approach. A contributing factor was the reported down draft.

- 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.
