Well into the producing the military Cessna T-37, Cessna set aside limited engineering and marketing resources to analyse the profitability of developing a civilian version of the T-37. Designated the Cessna Model 407, only a wooden fuselage mock-up of the proposed aircraft was ever produced.
The aircraft was to have a maximum take of weight of 9,300 lbs, with a cruising speed of 404 knots at 35,000 feet. The design was shown to military officials in September 1959.
Insufficient customer interest hindered its prospects.
