The Short SC.7 Skyvan (nicknamed the "Flying Shoebox") is a British 19-seat twin-turboprop aircraft manufactured by Short Brothers of Belfast, Northern Ireland. It is used mainly for short-haul freight and skydiving.
In 1958, Short was approached by F.G. Miles Ltd (successor company to Miles Aircraft) which was seeking backing to produce a development of the H.D.M.106 Caravan design with a high aspect ratio wing similar to that of the Hurel-Dubois HD.31. Short acquired the design and data gathered from trials of the Miles Aerovan based H.D.M.105 prototype. After evaluating the Miles proposal, Short rejected the Caravan. They developed their own design for a utility all-metal aircraft which was called the Short SC.7 Skyvan. The Skyvan is a twin-engined all-metal, high-wing monoplane, with a braced, high aspect ratio wing, and an unpressurised, square-section fuselage with twin fins and rudders. It was popular with freight operators compared to other small aircraft because of its large rear door for loading and unloading freight. Its fuselage resembles the shape of a railroad boxcar for simplicity and efficiency.
Construction started at Sydenham Airport in 1960, and the first prototype first flew on 17 January 1963, powered by two Continental piston engines. Later in 1963, the prototype was re-engined with the intended Turbomeca Astazou II turboprop engines of 520eshp; the second prototype (the first Series 2 Skyvan) was initially fitted with Turbomeca Astazou X turboprop engines of 666eshp but subsequently the initial production version was powered by Turbomeca Astazou XII turboprop engines of 690eshp. In 1967, it was found that the Astazou XII was temperature limited at high altitudes. Consequently, in 1968, production switched to the Skyvan Series 3 aircraft, which replaced the Astazou engines with Garrett AiResearch TPE331 turboprops of 715eshp. A total of 149 Skyvans (including the two prototypes) was produced before production ended in 1986.
Skyvans served widely in both military and civilian operations, and the type remained in service in 2009 with a number of civilian operators, and in military service in Guyana and Oman.
Two Argentine Naval Prefecture Skyvans later participated in the 1982 Falklands War. Both aircraft were ferried to Port Stanley in April 1982. One aircraft was damaged by British naval gunfire on Stanley racecourse, and did not fly again; it was finally destroyed by shellfire during British bombardments on 12/13 June 1982. The second aircraft was used at Pebble Island, where it became bogged down in the soft ground, and on 15 May 1982 it was destroyed by a British raiding party.
Skyvans continue to be used in limited numbers for air-to-air photography and for skydiving operations. In 1970, Questor Surveys of Toronto Canada converted the first of two Skyvan 3s for aerial geological survey work.
As of July 2009, a total of 40 Skyvan aircraft remained in airline service, with Pink Aviation Services (5), Sonair (1), Swala Airlines (2), Transway Air Services (1), Deraya Air Taxi (3), Layang Layang Aerospace (1), Macair Airlines (1), Malaysia Air Charter (1), Olympic Airways (1), Pan Malaysian Air Transport (1), Wirakris Udara (1), CAE Aviation (1), Deltacraft (1), Invicta Aviation (2), Advanced Air (1), Allwest Freight (2), Era Alaska (3), GB Airlink (1), North Star Air Cargo (5), Skylift Taxi Aereo (1), Skydive Arizona (7), Skydive DeLand (1), Skydive Lonestar (1), Skydive Perris, Sydney Skydivers (2),Skyforce Skydive Piotrkow Trybunalski, Poland Skydive Pennsylvania and Summit Air (2), Eagle Air (2), Sustut Air (1),Ryan Air Services, Nomad Air (2), Aalto University (Helsinki, Finland), Skykef (Israel)
As of September 2018, Skydive Lonestar no longer operates a Skyvan.
As of January 2019 Era Alaska, Ryan Air Services and All West Freight no longer operate Skyvans.
Sydney skydivers no longer own Skyvans.
As of May 2019, Olympic Air (successor to Olympic Airways) no longer operates Skyvans.
