Development and design
The Cunningham-Hall Aircraft Corporation was formed in 1928 and the first design was the PT-6, which first flew on April 3, 1929. The PT-6 was a biplane of all-metal construction with a fixed landing gear with tail skid. The cockpit held a pilot and either a copilot or passenger, with a separate cabin for four passengers. The aircraft was powered by a 300 hp (224 kW) Wright J-6 Whirlwind radial engine. Six PT-6 aircraft were built. One of these, serial number 2962, was reported to be in the museum collection of the Museum of Alaska Transportation (then in Palmer, now in Wasilla) in 1977, and has been listed on the National Register of Historic Places.[1]
The company's last design was a freighter conversion the PT-6F. First flown in 1937, the original passenger cabin was modified as a cargo compartment with 156 ft³ (4.42m³) of stowage space. A freight door was fitted to the fuselage and a loading hatch fitted in the roof. It was powered by a Wright R-975E-1 radial engine. An airworthy PT-6F is currently (2008) in a private collection at Anoka County-Blaine Airport, near Minneapolis.
