A.C. "Butch" Giessman formed Centurion Investments, Inc. in 1978. The company established itself as a source for surplus aircraft parts under the name Aviation Material and Technical Support. AVMATS was a pioneer in the concept of purchasing and dismantling airworthy and undamaged corporate aircraft to support the existing fleet of Sabreliners. We have grown substantially since 1978, expanding from parts sales into maintenance, interior refurbishment, accessory repair/overhaul, instrument repair, avionics repairs and installations, major airframe repair, modifications or inspections, engine overhaul, APU servicing, aircraft sales and more. Additionally, we have branched out a bit from Sabreliners and now proudly service and support Beechjet, Citation, Challenger, Falcon, Gulfstream, Hawker, Learjet, and Sabreliner aircraft.
After more than 40 years in business, AVMATS remains an American family-owned and operated business dedicated to providing the best value and top-notch service to our customers. Quality, technical accuracy, and competitive pricing have been prioritized by senior management's example. The frills and showcase cosmetics adopted by some service organizations have been intentionally avoided, freeing up valuable resources to pursue yet additional areas in the "total aircraft" concept. To date, the AVMATS family of companies occupies more than ten acres, at four physical locations, supporting 91,000 square feet of hangar and attached shops, over 100,000 square feet of warehouse facilities, 20,000 square feet of dedicated component and accessory overhaul space and 42,000 square feet of engine and APU shop space.
AVMATS Mission Statement
WE WILL WORK AS A TEAM, HOLDING THE UTMOST RESPECT FOR OUR CO-WORKERS, AS WE STRIVE TO MEET, HONOR AND EXCEED THE EXPECTATIONS OF OUR CUSTOMERS.
Aviation Material and Technical Support (AVMATS) was of the pioneers in providing alternatives for the support and maintenance of corporate aircraft. In response to customer requests for improved parts availability and more reasonably priced proprietary items, we set out to develop independent sources. Today's competitive parts pricing and conditional choices enjoyed by corporate operators can be largely attributed to AVMATS' unwillingness to accept the status quo of the industry.
Fueled by overwhelming customer acceptance, the years following 1978 produced enormous product diversity and geographical expansion. Accessory and component overhaul capabilities were added with the creation of Corpair Supply Company, Inc. now AVMATS Component Support of the Dassault Falcon 20, Lockheed Jetstar, and Raytheon Hawker 125 were included. Also, we received FAA certification for the overhaul of Rohr Thrust Reversers.
Another major milestone in offering alternative aircraft service and support was reached in 1991/1992 when we formed Aviation Turbines International, Inc. (ATI), now AVMATS Engine Support. Engine Support maintains FAA certification for Pratt & Whitney JT15D engine overhaul and the conditional inspection and repair of the Sundstrand T-62T-39 and T-62T-40C Series APUs. In addition, Engine Support offers a full lineup of services for the Honeywell GTCP 30/36 APUs.
In the late 1980s, four hangars and shop facilities were constructed at Spirit of St. Louis Airport to accommodate expansion into maintenance and structural repair services for the Falcon, Hawker, Sabreliner, Beechcraft, and Cessna aircraft. We added a full complement of avionics parts and installation sales along with the construction and certification of a fully equipped, state of the art instrument shop. Our shop began installing avionics upgrades including ELT, EGPWS, RVSM, and TCAS. We have established dealerships with all of the major avionics manufacturers. Additionally, we received a group certification STC for the installation of RVSM in the Sabre 65, Falcon 10, and Falcon 20. AVMATS is an Authorized Honeywell Line Service Center for the TFE731 and CFE738 engines as well as the GTCP30-92, GTCP36-6, and GTCP36-100/150 APUs. We also have capabilities to work on the Pratt & Whitney JT15D Engines as well as the Sundstrand T-62T-39 and T-62T-40C Series APUs.
Jet Support - MidAmerica
In 2003, AVMATS expanded to MidAmerica Airport (BLV) in Mascoutah, IL with the development of a 27,000 square foot facility, including 15,000 sq. ft. of hangar space and 6,000 sq. ft. of shop space. At this facility, we performed depot level services for the T39N aircraft for the US Navy for over 10 years. From 2003 until 2019, AVMATS performed FBO services but no longer offers FBO services at our AVMATS MidAmerica location. MidAmerica Airport offers the luxury of a 10,000 ft runway, very light traffic since it is outside the Lambert-St. Louis traffic pattern and MidAmerica Airport now provides the FBO services
Jet Support - Spirit
In 2019, AVMATS expanded our Spirit of St. Louis Airport (SUS) campus with the development of a 45,000 square foot facility including 35,000 square feet of floor space dedicated to aircraft maintenance. This addition increased the production capacity of Jet Support and allowed for more robust support of large body aircraft.
