NTSB narrative

THE EMS/MEDEVAC PILOT WAS PICKING UP A PATIENT AT A REMOTE SITE. AFTER THE PATIENT WAS LOADED, THE PILOT MADE A HOVER TURN AND DEPARTED THE SITE ALONG THE SAME ROUTE HE LANDED. AT 538 FEET EAST OF THE TAKEOFF SITE AND ABOUT 40 FEET ABOVE THE GROUND, THE HELICOPTER COLLIDED WITH A WIRE WHICH CROSSED ABOVE A HIGHWAY. THE SUPPORT WIRE SNAPPED AND CONTACTED THE MAIN ROTOR SYSTEM. THE HELICOPTER WAS LANDED, STRAIGHT AHEAD. THE PILOT REPORTED SEEING THE WIRE JUST PRIOR TO THE COLLISION. THE CREW RECEIVED A WIRE SURVEY FROM HIGHWAY PATROL PERSONNEL PRIOR TO LANDING AT THE SITE. THE HIGHWAY PATROL REPORTED THAT THERE WERE NO WIRES CROSSING THE ROAD.

Probable cause

THE PILOT-IN-COMMAND'S INADEQUATE VISUAL LOOKOUT. THE INCORRECT WIRE SURVEY GIVEN BY THE HIGHWAY PATROL PERSONNEL WAS A RELATED FACTOR.

  • 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.
  • API snapshot SHA-256: e5a7fe8809d82b8c0dd9c5bca38bed895f6634653bb5502a06b388dc779db28a; retrieved 2026-09-18T19:04:08.302Z.
