Silvercraft SH-4 (Italy)
First flown in March 1965, the SH-4 is a three-seat light general-purpose helicopter powered by a 175 kW (235 hp) Franklin 6A-350-D1B engine (derated to 127 kW; 170 hp). The standard version is suitable for pilot
training, utility, survey, police, ambulance, military liaison and observation duties. An agricultural version was also produced as the SH-4A. The SH-4/4A is no longer in production. A replacement for the SH-4 was built as the SH-200, first flown in April 1977.
