Title: Beechcraft T-1A Jayhawk

The T-1A was originally designed in Japan by Mitsubishi, to complement the existing MU-2 turboprop aircraft, and was known as the MU-300 Diamond. It first flew in 1978 and around 92 examples were built in Japan. Beechcraft bought the manufacturing rights in 1986, renamed it Beechjet 400 and built another 859 aircraft. 180 examples were purchased by the USAF as the T-1A, for advanced pilot training for pilots going on to fly tankers and transports, entering service in 1992.

This title contains the USAF flight manual for the T-1A Jayhawk, including the separate performance data manual, plus a nice brochure on the earlier Mitsubishi Diamond I executive jet aircraft. The files have been copied from the original flight manuals and retain any colour pages.
