TheAirco DH.9C was a British passenger aircraft.[1]
After World War I there were many surplusAirco DH.9 light bombers, designed byGeoffrey de Havilland, available for the emerging air transport business. At first stripped DH.9s were used to carry one passenger behind the pilot in the gunner's position, but later versions, designated DH.9B, added a second passenger seat ahead of the pilot. A second seat behind the pilot was added by extending the rear cockpit in the early DH.9C. Later it had this rear position converted to hold two passengers face to face, protected by a faired dorsal canopy or cabin. Most of these later four-seat aircraft had slight sweepback to counter the rearward shift in thecentre of gravity.[1][2]
The DH.9, DH.9B, and DH.9C were dimensionally similar, with the same wingspan and height and only small variations in length depending on the powerplant. They were two-bay tractor biplanes, with fixed two-wheel main and tail-skid undercarriage. Their structures were of spruce and ash, wire-braced and fabric-covered.
The first four-seat, swept DH.9C,G-EAYT received its certificate of airworthiness on 13 January 1922.[3]
Nineteen aircraft were produced for operators, 13 in theUnited Kingdom, three inAustralia, and three inSpain. The last in service was operated by Northern Air Lines inBarton, Greater Manchester, until 1932.[1]
