August 1987: MARC became a not-for-profit consortium sponsored by St. Louis' three adult trauma centers. The name "ARCH" was selected to identify the cooperative effort. Officially named, "ARCH Air Medical Services".
1989: Paramedic added to the crew mix of pilot/registered nurse.
1990: ARCH replaced the Bell JetRanger with the MBB/Kawasaki BK 117 aircraft, offering cabin class, twin-engine, space, speed and safety.
1990 also saw the addition of 'fixed-wing' services when it added a Beechcraft King Air for longer distance transports, flights in inclement weather which prohibit rotor wing flights and specialty teams.
1993: ARCH opens their own Communications Center after having this service done by a sister Ambulance Company owned by the Consortium to meet its own special needs.
1997-2000: ARCH and Mid-America Transplant, both nonprofits, buy services from for-profit SkyLife. But they get services at a 10 percent to 15 percent discount to the cost they were previously paying to charter air services. Skylife therefore expands their 'fixed-wing service' starting with ARCH's two Beechcraft King Air and adding two Diamond 1A jets and one Baron 58. Based at Spirit of St Louis Airport this service would be available for Organ Procurement Teams and Corporate Charters. SkyLife had contracts to provide critical care transport services with the Regional Organ Bank of Illinois in Chicago, the Iowa Statewide Organ Procurement Organization in Iowa City and Barnes-Jewish Physician Services. As well as previous commitments with Cardinal Glennon Children's Hospital, St Johns Mercy Medical Center and St Louis Children's Hospital Specialty transport teams.
2000: ARCH Air Medical Services, Inc. was acquired by Air Methods Corporation, which operates air ambulance programs across America. 2000 also saw the acquisition of LifeBeat Air Medical, from Southeast Missouri Hospital. ARCH is now known as Arch Air Medical Service. Air Methods was not interested in SkyLife Aviation and did not purchase that part of ARCH and therefore Skylife closed their doors December 31, 1999.
2009: Arch now utilizes the Bell 407 and Eurocopter EC130's for many outlying bases as well as the BK-117s and EC-135s.
For over 30 years: Arch Air Medical Service has operated an accident free safety record
Current Arch Air Medical Service bases
The Helicopter Service area is around 150 miles around each base. In 2014, Arch relabeled all of its bases and now the call sign doesn't change regardless of the aircraft in use.
In 2013, Arch closed its fixed wing program due to low volumes and the parent company, Air Methods, providing this service through their newly acquired company American Jets. In 2012, Air Methods opened its central dispatching center in Omaha, Nebraska and Arch dispatch was removed from service. Also included in the Arch region are the following community-based services.
