TAS Aviation is the leader in Twin Cessna maintenance. For over 40 years we have been setting the industry standard on all things Twin Cessna. Located on Defiance Memorial Airport (DFI) in Defiance Ohio, our company was founded in 1976 by Tony Saxton and his father Vernon. Their expertise came when they began maintaining and operating a fleet of Cessna 310's that flew checks from across the midwest to the Federal Reserve in Cleveland. From there, the company's expertise grew as they began to develop as the leading expert on the operation of all Twin Cessna aircraft.
