The de Havilland DH.50 was a 1920s British large single-engined biplane transport built by De Havilland Aircraft Company at Stag Lane Aerodrome, Edgware and licence-built in Australia, Belgium and Czechoslovakia.

History

De Havilland realised that war surplus aircraft would so need replacing the company designed a four-passenger cabin monoplane the 'de Havilland DH.50 using experience gained with the earlier de Havilland DH.9. The first DH.50 G-EBFN flew in August 1923 and was used within a few days by Alan Cobham to win a prize for reliability during trial flights between Copenhagen and Gothenburg. Only 17 aircraft were built by de Havilland the rest were produced under licence. Different aircraft had a wide variety of engine fits.

In 1924 Cobham won the King's Cup Race air race in G-EBFN averaging 106 mph. Cobham made several long range flights with the prototype until he replaced it with the second aircraft. The second aircraft G-EBFO was re-engined with the Armstrong Siddeley Jaguar engine and was designated the DH.50J. Cobham flew the aircraft on a 16,000 mile (25749 km) flight from Croydon Airport to Cape Town between November 1925 and February 1926. The aircraft was later fitted with twin floats (produced by Short Brothers at Rochester) for a survey flight of Australia in 1926. On the return flight from Australia to England Cobham's engineer (A.B. Elliot) was shot by a stray bullet when overflying the desert between Baghdad and Basra.

Licence Production

The aircraft was popular in Australia and licence production was agreed with 16 aircraft built in Australia. Four DH.50As and three DH.50Js by QANTAS, Western Australian Airlines built three DH.50As and Larkin Aircraft Supply Company who built one DH.50A. Three DH.50A were built by SABCA at Brussels and seven by Aero at Prague. One of the QANTAS built aircraft G-AEUR was the first aircraft used by the Australian Royal Flying Doctor Service.
