ThePasotti F.9 Sparviero (English:Sparrowhawk) was a four-seat, low-wing touring aircraft, built inItaly in the 1950s. Designed byStelio Frati, it was a single-engine version of his earlier twin-enginedAirone. Only one was built.
The F.9 Sparviero was a single-engined version of the earlier, twin-enginedF.6 Airone, both Stelio Frati designs. The two aircraft shared many constructional details and had almost the same dimensions and weights, though the Sparviero's nose-mounted engine extended thefuselage. Engine layout apart, the two were very similar in appearance; they also both failed to reach production and only one Airone and one Sparviero were built.[1][2]
The Sparviero had an all-wood,low mountedcantilever wing ofisosceles trapezoidal plan, built around a singlespar and covered with stressedplywood skin, withdifferential ailerons andtrailing edgeflaps. The fuselage was a ply skinned woodenmonocoque, built in two sections which bolted together just aft of the wings. The forward part held the cabin, which seated four in two pairs, with access via two wide doors over the wings. The roof line of the cabin continued aft into that of the rear fuselage.[1] The Sparviero was initially powered by a 250 hp (187 kW)Hirth invertedV-8 air-cooled engine, though it was the intention to replace this with a 260 hp (194 kW)Lycoming horizontally opposed engine in production models[1] and the prototype received one later.[3] Fuel was fed from three tanks, two in the wings and one in the fuselage. The tail unit was conventional, with the tailplane just above the fuselage. The latter tapered in height rearwards, and thefin merged into it with adorsalfillet. Theempennage construction was similar to that of the wing, except that the control surfaces werefabric-covered. Thetricycle undercarriage was retractable and fitted withhydraulic brakes.[1]
The Sparviero first flew on 27 July 1956,[4] piloted by Vico Rocaspina who was responsible for all the early flight programme.[2]
The only Sparviero built,I-HAWK, was in private hands by April 1958,[5] based atMilano Linate and was still there in July 1964.[6] It was withdrawn from use in 1968 and presented to the Milan Science Museum in 1972.[7]
