Eurocopter EC135 / H135 Safety Record — Light Twin EMS | AeroGurus

Editorial safety summary — see Eurocopter H135 listings and consult a qualified A&P/inspector for individual aircraft decisions.

The Eurocopter EC135 / H135 has a strong safety record as the European EMS/HEMS standard — twin-engine redundancy (Safran Arrius or Pratt & Whitney), the Fenestron shrouded tail rotor (safer around the ground and quieter), modern avionics, and a flat-floor cabin designed for medical operations. Twin-engine redundancy provides genuine safety benefit for the demanding EMS night/weather mission. Fleet accidents are dominated by EMS mission risk (night, weather, off-airport landing zones) rather than airframe or engine issues; professional training and operational standards drive the strong record.

Common safety topics

  • Twin-engine redundancy — genuine engine-out safety margin for EMS/IFR.
  • Fenestron tail rotor — shrouded design; ground-safety and noise advantage.
  • EMS mission risk — night, weather, off-airport LZs — demand professional training.
  • Component overhauls — rotor head, gearboxes, blades.
  • Engine choice — Safran Arrius or P&W PW206; verify both engines' status.

Pre-buy safety checklist
