Promavia Jet Squalus

The Promavia F.1300 Jet Squalus, also known as Promavia Jet Squalus F1300, was a two-seat light jet trainer designed by Italian Stelio Frati and built by Promavia in Belgium with support from the Belgian government.

Development
The Jet Squalus was designed by Frati and based on his earlier lightweight jet trainers the F.5 Trento and the F.400 Cobra. It was a low-wing cantilever monoplane with retractable landing gear. The Jet Squalus was powered by a Garrett TFE109 turbofan with engine intakes in above the wing root. The prototype, registered I-SQAL, first flew on 30 April 1987. The aircraft was fitted with four underwing hard points for disposable stores to allow weapons training.

Operational history
With the demise of the similar American Fairchild T-46 trainer in 1986 the support for the engine disappeared and it was planned to re-engine with the Williams-Rolls FJ44. The aircraft was exhibited at the Farnborough Air Show in September 1988, but the project folded and Promavia went bankrupt in 1998. An unflown second prototype was to be modified for airline pilot training, and the unfinished third prototype was to be pressurised.
