As at least the designation "F.400" was already mentioned here, I add this drawing of the
F.400, although there really aren't many similarities. This F.400, named "Condor" would
have had about 8 seats (not mentioned in the short caption) and two Turboméca Astafan
engines. Looks like an enlarged F.480.
(from InterAvia 9.72)

The F.400 Cobra was a two seat jet, I suspect the caption in the Interavia article is incorrect.

It may be one of his designs but it is not the F.400.

You are absolutely right my dear Jemiba,

but InterAvia was wrong in its model,it was called F.22 Jet Condor
a project of 1972 with two Turbomeca Astafan engines and 8-seat,
it was mention in the book;Airlife's General Aviation and the F.22
later re-allocated to F.22 Pinguine side-by-side two seat trainer.
 
Hi,


F.3500 Sparviero was a 19-seat twin turbofan high-wing light commuter aircraft project of 1983.

As I understand,

there was a variant from F.6 Airone,but powered by single engine and not two,maybe it
was a Project ?.

Hi Hesham :D
That could be the F-9 Sparviero built by Passotti. Only a single example (I-HAWK) was constructed.
Please find a photo and some details.
4-seat sport
one 240hp Lycoming GO-435-C2 piston engine
max. speed 197 mph, cruise 160 mph, icr 1,200ft/min. ceiling 15,800ft, range 940 miles
wingspan 32.808ft; length 27.229ft
DETAILS: The F-9 Sparviero was more or less a single-engine derivative of the F-6 Airone (qv) using similar wings, tail surfaces and fuselage. It was designed by Mr. Stelio Frati and built by Legnami Pasotti SpA and only a single aircraft (registration I-HAWK) was produced. The aircraft was first flown on 27 July 1956 with one 240hp Hirth HM508 (V8) engine, but at a later stage the F-9 was re-engined with one 240hp Lycoming GO-435. The aircraft later went to the National Museum of Science and Technology in Milano. No further development took place.
Production: 1
