Beech 73 Jet Mentor
The Model 73 private initiative was inspired by the T34 Mentor and used T-34 parts in the construction of this two-seater jet.
The major differences are a new design of the rear fuselage and the elevation of the stabilizer to clear the engine nozzle. The engine selected was a Continental YT69 T-9 (Marbore II built under license) of 417 Kp thrust.
On December 18, 1955, Beechcraft test pilot Tom Gillespie made the first flight of the Jet Mentor.
The Model 73 was studied by military programs at the time, but never receive any official order. The choice of the U.S. Navy for the Temco TT1 Pinto and the U.S. Air Force in the Cessna T37 meant the final abandonment of the project.
Beech retained the one prototype built during which the test flights continued. Then the plane was stored outside behind a shed.
In the 1960s it was given to a local technical school where it remained for the next 40 years.
Recovered by the Wichita Kansas Aviation Museum, it is stored for many years on an outside car park.
