variants with their own articles=The AASI Jetcruzer is a US single
turboproplight civil transport made by AASI. The Jetcruzer has an unusual configuration, with a single turbopropengine driving a pusher propeller, prominent canards, and fins mounted at the ends of its swept wings. The plane has seating for up to six people including the pilot. The Jetcruzer is noteworthy in being the first aircraft to have achieved a spin resistance certification from the United States FAA.
Work on the Jetcruzer began in March 1983, with the
prototypefirst flying on January 11 1989. This initial version, designated the Jetcruzer 450 seated six people (including the pilot) and was powered by an Allison 250-C20S. It gained an FAA type certification on June 14 1994. Three prototypes were built, but AASI chose not to market this aircraft, in order to focus on more advanced versions. A spin recovery systemfor use in the flight test program was designed for the aircraft by Butler Parachute Systemswhich also worked on one for the Swearingen SJ-30.
The first version developed from the 450 was the Jetcruzer 500, a slightly stretched version powered by a
Pratt & Whitney Canada PT6A-66A and featuring cabin pressurization. Two of the 450 prototypes were converted to this configuration, and first flew in this form on August 22 1997. This was the version selected for production, and at one point, AASI had orders for some 200 aircraft at $US 1.6 million each. A military version, the ML-2 had also been offered, as well as a UAV, the ML-1
None of these orders would be filled, however, as the Jetcruzer 500 remained uncertified and its development slowly stagnated. Specific problems with the aircraft's noise, high stall speed, and
center of gravitywere not overcome before all work on it was suspended in 2002. Nearly 20 years of work had still not resulted in a marketable aircraft.
In December 1992, construction work began on the prototype of an even larger variant, the Jetcruzer 650, which was to seat up to thirteen. This was quickly abandoned as the company's financial problems required resources to be focused on the 500. A military version would have been the ML-4
turbofan-powered version was planned as the Stratocruzer 1250, but never left the drawing board. Design work had started in September 1991 to provide a business jet with intercontinental range. A military version, the ML-5 intended for surveillance duties, was also planned. Work was abandoned after AASI failed to attract financial backers for the project in 1995.
In November 2003, AASI (by now, MASG) offered the entire Jetcruzer project for auction, and sold it to
Innova Aircraftin February 2004. Shortly after the purchase, Innova announced its intentions of offering a new version of the aircraft in kit form, marketed by a new subsidiary, Jetcruzer LLC. This will feature a modified wing to overcome the problems faced by the Jetcruzer 500, and will be powered by a pair of Pratt & Whitney Canada JT15Dturbofans. It is expected to fly by late 2004 or early 2005.
