    Description

    The Short 330 (also SD3-30) is a small turboprop transport aircraft produced by Short Brothers.

    General Information

     It seats up to 30 people and was relatively inexpensive and had low maintenance costs at the time of its introduction in 1976. The 330 was based on the SC.7 Skyvan.

     

    The Short 330 was developed by Short Brothers of Belfast from Short's earlier Short Skyvan STOL utility transport. The 330 had a longer wingspan and fuselage than the Skyvan, while retaining the Skyvan's square-shaped fuselage cross section, allowing it to carry up to 30 passengers while retaining good short field characteristics. The first prototype of the 330 flew on 22 August 1974.

     

    The Short 330 is unusual in having all of its fuel contained in tanks located directly above the ceiling of the passenger cabin. There are two separate cockpit doors for pilot and co-pilot for access from inside the cabin.

     

    While Short concentrated on producing airliners, the design also spawned two freight versions. The first of these, the Short 330-UTT (standing for Utility Tactical Transport), was a military transport version fitted with a strengthened cabin floor and paratroop doors,[7] which was sold in small numbers, primarily to Thailand, which purchased four. The Short Sherpa was a freighter fitted with a full-width rear cargo door/ramp. This version first flew on 23 December 1982, with the first order, for 18 aircraft, being placed by the United States Air Force (USAF) in March 1983, for the European Distribution System Aircraft (EDSA) role, to fly spare parts between USAF bases within Europe. Subsequently, a further 16 were ordered as C-23B Sherpas.

     

    The basic Short 330 was a passenger aircraft intended as a short-range regional and commuter airliner, and had been designed to take advantage of US regulations which allowed commuter airlines to use aircraft carrying up to 30 passengers, thereby replacing smaller types such as the Beechcraft Model 99 and the de Havilland Canada DHC-6 Twin Otter. The Short 330 entered service with Time Air (a Canadian airline) in 1976. Despite its somewhat portly looks (one regional airline affectionately dubbed it the "Shed" ), it soon proved to be an inexpensive and reliable 30-seat airliner. The 330's design was refined and heavily modified, resulting in the Short 360.
