Survival Flight In 1983 UMHS established Survival Flight, the first of its kind in the state. The service operates three American Eurocopter EC155 B1 helicopters and one Bombardier Learjet 75 fixed-wing, twin-engine jet. For its first, ten years, the service flew American Eurocopter AS355 Twinstar craft, which were replaced in 1993 with Bell 230 craft that remained in service for five years, until they were replaced in 1998 with Bell 430 craft. From 2012 to the present, the service has used three Eurocopter EC-155. The four aircraft make 1000 to 1500 trips annually and have a range of over from the U-M campus. The flights transport 800 to 1000 patients per year with the remainder of the trips for the transport of human organs. The jet also transported victims of the 2010 Haiti earthquake for treatment in the United States. In addition to its main helipad on the U-M medical campus, Survival Flight operates out of Livingston County Airport, in a hangar that it shares with Livingston County EMS. Survival Flight has an excellent safety record and intense maintenance program. The aero-medical aviation sector has a high accident rate per hours flown due to its requirement to operate in almost all weather conditions and due to urgent transportation needs. Survival Flight has only suffered one crew and equipment loss.
