After spending 40 forty plus years in the aircraft maintenance industry as an A & E mechanic, an aircraft electrician and an aircraft instrument repair technician, Ralph Graves purchased an aviation service company in the early 1990s. Incorporating it as ASCO Aeronautical, Inc. Ralph used it as a platform to manufacture and sell some of the aviation related test equipment he had helped to develop. Since then, ASCO Aeronautical, Inc. has developed into distributors and dealers for several well know companies, as well as a manufacturer of test equipment.
