NTSB narrative

The pilot of the helicopter reported that, he was on the ramp with the engine running to accomplish a rapid refuel. The fueler was attempting to attach the grounding cable to the helicopter and due to the cable not locking, he maneuvered the cable up and down, which then contacted the main rotor blades. The pilot reported he felt a “violent jolt” and immediately shut the engine down. The fueler’s hands were seriously injured. The main rotor blades were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

Probable cause

The fuelers improper action during the refueling process.

  • 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, coordinates, cause areas. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2022-04-17.
