NTSB narrative
According to a Federal Aviation Administration inspector, the helicopter’s owner, who held a student pilot certificate, flew with a passenger from a local airport to a lake house. Upon departure from the lake house, the passenger was at the controls of the helicopter. As the helicopter started to lift off from the ground, it made a sharp turn to the right. The student pilot added that he was unable to take the controls from the passenger and regain control of the helicopter. The helicopter’s tailrotor struck the ground and the helicopter subsequently rolled left and into the lake, where it sustained substantial damage to the fuselage, tailboom, main and tailrotor blades.
Probable cause
The student pilot’s improper decision to carry an unauthorized passenger and the passenger’s loss of control of the helicopter during take-off.

- 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.
