NTSB narrative
The pilot reported that, while hovering the helicopter to park between three stationary helicopters, the ground crew gave him the signal for a 180° "pedal turn." As the helicopter was about to touch down, he felt a shudder in the airframe. He then immediately rolled the throttle closed and completed an emergency shutdown.
Postaccident examination revealed that the tail rotor blades struck the main blades of a stationary helicopter, which likely caused the shudder felt by the pilot.
The helicopter sustained substantial damage to the tail rotor and main rotor systems.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable cause
The pilot’s failure to maintain clearance from a stationary helicopter during landing. Contributing to the accident was the ground crew’s failure to ensure that the helicopter would clear the stationary helicopter.

- 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. 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.
