FIRE The safety of the helicopter occupants is the primary consideration when a fire occurs. Therefore, if airborne, it is imperative that the pilot maintain control of the aircraft and land immediately.
Page 52 CSP-HE/HS-1 MD 500 ROTORCRAFT FLIGHT MANUAL Emergency and (Models 369HE/HS/HM) Malfunction Procedures Procedures: Aircraft Evacuation A thorough preflight passenger briefing is essential for a quick and safe evacuation of passengers and crew when fire is involved. How to release seat belts, the opening of doors, the proper exiting of the helicopter keeping head and hands low to avoid the main rotor, are all critical to insure the safety of passengers and crew.
