The Short 330 (also SD3-30) is a small turboprop transport aircraft produced by Short Brothers. 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 C-23 Sherpa was a military version of the 330. Production of the aircraft ended in 1992, after 141 were produced. The Short 360 was a development of the Short 330.
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. [4] The first prototype of the 330 flew on 22 August 1974. [5]
The Short 330 is unusual in having all of its fuel contained in tanks located directly above the ceiling of the passenger cabin. [5] There are two separate cockpit doors for pilot and co-pilot for access from inside the cabin. [6]
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, [7] 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. [7] Subsequently, a further 16 were ordered as C-23B Sherpas. [2] [3]
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, [8] 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" [9] ), it soon proved to be an inexpensive and reliable 30-seat airliner.
The 330 was somewhat slower than most of its pressurised competition, but it built up a reputation as a comfortable, quiet and rugged airliner. [10] The quiet running of the Pratt & Whitney PT6A-45R was largely due to an efficient reduction gearbox. [10] The cabin was the result of a collaboration with Boeing engineers who modelled the interior space, fittings and decor after larger airliners. The use of a sturdy structure complete with the traditional Short braced-wing-and-boxy-fuselage configuration also led to an ease of maintenance and serviceability. [10]
Production ended in 1992 with a total of 141 being built (including freighter and military versions). [11] As of 1998, approximately 35 were still in service. The 330's design was refined and heavily modified, resulting in the Short 360.
The aircraft is popular with air charters, small feeder airlines, and air freight companies. [13]
As of May 2017 [update] , the aircraft type has suffered three fatal accidents in civilian use:
In addition to these three accidents, there have been at least sixteen hull-loss occurrences, i.e., non-fatal accidents in which planes were damaged beyond repair. [22]

An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a long, tube shaped, and jet powered aircraft. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts.
The ATR 42 is a regional airliner produced by Franco-Italian manufacturer ATR, with final assembly in Toulouse, France. On 4 November 1981, the aircraft was launched with ATR, as a joint venture between French Aérospatiale and Aeritalia . The ATR 42-300 performed its maiden flight on 16 August 1984 and type certification was granted during September 1985. Launch customer Air Littoral operated its first revenue-earning flight in December of that year.
The Cessna 208 Caravan is a utility aircraft produced by Cessna. The project was commenced on November 20, 1981, and the prototype first flew on December 9, 1982. The production model was certified by the FAA in October 1984 and its Cargomaster freighter variant was developed for FedEx. The 4 ft (1.2 m) longer 208B Super Cargomaster first flew in 1986 and was developed into the passenger 208B Grand Caravan.
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996.

The Short C-23 Sherpa is a small military transport aircraft built by Short Brothers. It was designed to operate from unpaved runways and make short takeoff and landings (STOL). It features a large squared fuselage with a full-width rear cargo door/ramp. The C-23A and C-23B are variants of the Short 330 and the C-23B+ is a variant of the Short 360. 60 aircraft were used it was finally retired from US service in 2014, but remains in international service. Although it was widely used for other uses it was originally the winner of an early 1980s competition for a light cargo aircrat to deliver cargo, especially aviation parts, for EDSA. While the C-23 was a new production, as was the C-23B, the C-23B+ were actually Shorts 360, with the tail and rear fuselage of a C-23. One of the differences between the C-23 and C-23B, is that the later had cabin windows. The aircraft has a substational amount of civilian use and also was operated by the U.S. Forestry Service and NASA for example. The NASA C-23 is still in service and used for research. The aircraft continues in service with the Philippines and Djibouti, as well as various civilian and governmental agencies, such as the aforementioned NASA research Sherpa.

Passenger amenities are removed or not installed, although there are usually basic comfort facilities for the crew such as a galley, lavatory, and bunks in larger planes. Freighters may be operated by civil passenger or cargo airlines, by private individuals, or by government agencies of individual countries such as the armed forces.
