The Silvercraft SH-4 was the first Italian designed helicopter to gain Italian and FAA certification. The prototype was first flown in October 1963 with development assisted with both financial and technical help from SIAI-Marchetti. The helicopter was a conventional design with two-blade main rotor and tail rotor, a skid landing gear and a high-set tubular corrugated tailboom. It is powered by either a 200 hp (149 kW) or 235 hp (175 kW) Franklin 6A-350 engines which have been flat-rated to 170 hp (127 kW). Some SH-4s were equipped with Lycoming LHIO-360-C1A engines of 205 hp (153 kW).[1]
Two aircraft were evaluated by the Italian Air Force.
An upgraded development, the SH-200 was developed from the SH-4 but was only flown as a prototype.
