Maverick Air TwinJet
Bob Bornhofen was retired when he got into the aviation business, and had no aviation background. He wondered why he couldn't buy a personal jet, and in 1998 he decided to create one. Bornhofen has been funding much of the project out of his own pocket.
To be marketed as a kit, the Twinjet has a pre-preg eglass composite airframe with carbon fiber control surfaces and empennage.
The TwinJet was not certified because it uses two converted surplus GE-T58 military helicopter engines (overhauled and zero-timed).
The TwinJet was designed in anticipation of the FJX-2 engine, which was being developed under the General Aviation Propulsion program. The FJX-2 was going to be a new generation turbofan engine producing 700-800 pounds of thrust.
When delays occurred for that engine, Bob Bornhofen elected to use the T58 engines so he wouldn't slow the TwinJet development.
The first prototype was flight tested to about 370 knots during a series of tests to determine if the aircraft had any major certification-related problems.
