Pilatus-Flugzeugwerke AG of Stans, Switzerland designed their PC-6 Porter
to fulfil a range of utility roles and managed to build a rugged and
reliable aircraft with excellent landing and takeoff ability on short and
rough landing grounds. The prototype flew for the first time in May 1959.
The first production aircraft was delivered in 1960 and was powered by a
six cylinder Lycoming GSO480 piston engine, but soon a turboprop-powered
variant was developed. The first PC-6A Turbo Porter flew in May 1961. The
aircraft was equipped with a 523 hp Turboméca Astazou IIE/G turboprop
engine.
The Swedish Army Aviation leased a PC-6A Turbo Porter for testing
in 1964. The aircraft carried Pilatus’ construction number 570. It was
painted blue and white and was fitted with markings according to the
normal Army standard, but lacked registration number.
In the beginning of 1965, the Porter participated in exercises during
harsh winter conditions in north Sweden. The Army Aviation also tested two
other types of aircraft – the British Beagle Husky and two of the small
helicopter Hughes 269. The helicopters were kept and got the designation
HKP 5A, but the Pilatus and the Beagle were returned to the
suppliers.
After its short visit to Sweden, the Pilatus PC-6A was sold to Air
America and got the American civil registration code N9445. The
Central Intelligence Agency (CIA) owned Air America. During the Vietnam
War, the organization flew a variety of missions in the Far East. Air
America was wound up in 1976.
