The de Havilland DH.114 Heron is a small propeller-driven British airliner that first flew on 10 May 1950. It was a development of the twin-engine de Havilland Dove, with a stretched fuselage and two more engines. It was designed as a rugged, conventional low-wing monoplane with tricycle undercarriage that could be used on regional and commuter routes. A total of 149 were built; it was also exported to about 30 countries. Herons later formed the basis for various conversions, such as the Riley Turbo Skyliner and the Saunders ST-27 and ST-28.

Design

In the closing stages of the Second World War, the aircraft manufacturer de Havilland began development of a new small twin-engined passenger aircraft, the DH 104 Dove, intended as a replacement for the earlier Dragon Rapide and which soon proved to be successful. As a further development, the company basically enlarged the Dove; the fuselage was lengthened to make room for more passengers or freight, and the wingspan was increased to make room for two more engines. The Heron was of all-metal construction, and was laid out as a conventional design; the resulting aircraft could use many of the parts originally designed for the Dove, thus simplifying logistics for airlines using both types..

The first Heron, Series 1A suffered deficiencies, as NAC soon discovered. First, the aircraft was generally underpowered. Its quite heavy engines (weighing about 490 pounds (220 kg) each), had an output of only 250 hp (190 kW) each
