Home About Companies Services Media Center Open Positions Contact History Leadership Tailwind While Greenwich AeroGroup was established in 2007, the history of our companies took wing decades ago — not long after fixed-wing powered flight became a reality. Greenwich AeroGroup’s oldest company, MK Aviation, was founded by Morrison Knudson in 1957 to maintain its fleet of DC-3s supporting the Hoover Dam project; it became Western Aircraft in the 1980s. In 1960, Summit Aviation was founded to provide air freight services and became a repair station in 1966. Next came the formation of Professional Aviation Associates in the 1980s and Professional Aircraft Accessories in the 1990s. Greenwich AeroGroup owns and operates providers of general, commercial, government and military aviation services including maintenance, avionics and interior refurbishments; fixed base operations; aircraft sales, charter and management; manufacturing and engineering; component repair and overhaul and parts distribution. Current locations include Professional Aircraft Accessories, located in Titusville and Miami, Fla.; Professional Aviation Associates, located in Atlanta, Ga.; Summit Aviation, located in Middletown, Del.; Kernersville, N.C. and Somerset, Ky.; and Western Aircraft, located in Boise, Idaho.
