The Boeing Model 247 was an early United States airliner, considered the first such aircraft to fully incorporate advances such as all-metal (anodized aluminum) semi-monocoque construction, a fully cantilevered wing and retractable landing gear. Other advanced features included control surface trim tabs, an autopilot and deicing boots for the wings and tailplane.
On 8 February 1933, Boeing flew the prototype of a new civil airliner which was identified by the company as the Boeing Model 247. This had derived via the design of the single-engined civil Model 200 Monomail and the twin-engined Model 215 (US Army designation B-9) bomber, each of which had a cantilever monoplane wing.
A revolutionary aircraft, the Boeing 247 has since become regarded as a prototype for the modern airliner, for it was a clean cantilever low-wing monoplane of all-metal construction with twin-engine powerplant, retractable landing gear, and accommodation for a pilot, copilot, stewardess and 10 passengers. With one engine inoperative it could climb and maintain altitude with a full load, and introduced a new feature for a civil transport aircraft by being equipped with pneumatic de-icing boots on wing, tailplane and fin leading edges to prevent ice accretion from reaching a dangerous level.
When the USA became involved in World War II in late 1941, these Model 247Ds remained in airline use, and 27 of them were impressed for service with the USAAF under the designation C-73. It had been anticipated that they could be used for the carriage of cargo and troops, but it was discovered that the cabin doors were too small for this purpose. Instead, they were deployed to ferry aircrew and, later in the war, were used for training. In service they were provided with 447kW Pratt & Whitney R-1340-AN-1 Wasp radials. When no longer required in late 1944, they were returned to civil airline service.
60 Boeing 247 were operated by Boeing Air Transport (later United Air Lines) since 1934.
