The Fairchild T-46 was an American light jet trainer aircraft of the 1980s. It was cancelled in 1986 with only three aircraft being produced. Design and development The United States Air Force (USAF) launched its Next Generation Trainer (NGT) program to replace the Cessna T-37 Tweet primary trainer in 1981. Fairchild-Republic submitted a shoulder-winged monoplane with a twin tail, powered by two Garrett F109 turbofans and with pilot and instructor sitting side by side. Part of the rationale was an expectation of increasing levels of general aviation traffic. A pressurized trainer would permit training at higher altitude, leading to fewer restrictions on the new pilots. In order to validate the proposed aircraft's design, and to explore its flight handling characteristics, Fairchild Republic contracted with Ames Industries of Bohemia, New York to build a flyable 62% scale version. Burt Rutan's Rutan Aircraft Factory (RAF) in Mojave, California was contracted to perform the flight test evaluations, with test pilot Dick Rutan doing the flying. The scale version was known at RAF as the Model 73 NGT, this flying on 10 September 1981. One requirement was for the aircraft to be able to go into a spin, but to also have easy recovery from the spin. This was demonstrated using the Model 73 NTG. Fairchild's design, to be designated T-46, was announced winner of the NGT competition on 2 July 1982, with the USAF placing an order for two prototypes and options for 54 production aircraft. It was planned to build 650 T-46s for the USAF by 1991. The aircraft first flew on 15 October 1985, six months later than originally programmed date of 15 April. Costs had increased significantly during the development process, with the predicted unit cost rising from $1.5 million in 1982 to $3 million in February 1985. The 1985 Gramm–Rudman–Hollings Balanced Budget Act mandated spending cuts for the US government in an attempt to limit the national debt, and while testing did not reveal any major problems, Secretary of the Air Force Russell A. Rourke cancelled procurement of the T-46, while allowing limited development to continue. While attempts were made in Congress to reinstate the program, which resulted in the FY 1987 budget being delayed, an amendment was passed to the 1987 Appropriations Bill to forbid any spending on the T-46 until further evaluation of the T-46 against the T-37 and other trainers took place. The project was cancelled
