The Pilatus PC-7 is based on the Pilatus P-3 and the first prototype, actually a P-3 of which the Lycoming engine was replaced by a P & W PT6A-20 turboprop, made its first flight in April 1966.
The program was seriously delayed by a crash and just in 1975 a second prototype, also a converted P-3, made its maiden flight.
There were all kinds of modifications, such as a new wing with integrated fuel tanks, a modified tail and a tear drop cockpit.
In August 1978 the first production exampled rolled out and by the end of the year, the type received its Swiss type certification.
Soon the delivery of the PC-7 to both civilian and military users followed.
The PC-7 Mk. II is actually a development of the PC-9, and adapted to the smaller of the turboprop PC-7. Goal was reducing the cost of operation and maintenance.
