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.

Key Information

Development

[edit]

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]

Operational history

[edit]
Mississippi Valley Airlines's Short 330 at Saint Paul International Airport in 1985

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 Short 330's unpressurized but comfortable cabin and reliable performance in austere environments solidified its niche in regional , particularly for island-hopping routes and remote .

Design and development

Origins

The Short 330 originated as a development of the , a versatile utility aircraft introduced in 1963 that typically accommodated 19 passengers. in , , extended the Skyvan's fuselage by approximately 12 feet 5 inches to increase capacity to 30 passengers while retaining its core characteristics for operations on short, unprepared runways. This derivation leveraged shared components from the Skyvan to minimize development costs and accelerate the project, which began with initial sketches and feasibility studies around 1972. The design emphasized short-haul regional transport, featuring a distinctive boxy that facilitated straightforward loading and unloading of passengers or through a large rear door. A high-wing configuration enhanced propeller clearance and stability during rough-field landings, while all fuel tanks were uniquely positioned directly above the passenger cabin ceiling to preserve an unobstructed floor space below. These elements reflected ' focus on practicality and versatility for feeder routes. In the early , the aviation market sought economical to succeed aging DC-3s on regional networks, prioritizing low operating costs and reliability. The Short 330 addressed this demand by offering a modern, unpressurized alternative priced under $1 million, far surpassing the DC-3 in performance while building on proven Skyvan reliability.

Development and certification

The development of the Short 330 began with the construction of its at ' facility in , , starting in August 1973. The aircraft, registered G-BSBH and designated as the SD3-30, was powered by two PT6A-45 engines and incorporated design elements derived from the earlier Short Skyvan, including a boxy square-section for ease of loading. This made its on 22 August 1974 from Sydenham Airport in , marking the initial evaluation of its short takeoff and landing (STOL) capabilities and overall airframe performance. Following the first flight, an extensive program was undertaken at Sydenham Airport to assess performance, flight stability, and systems integration. The tests confirmed the aircraft's rugged utility, with key design features such as the high-mounted wing and fins contributing to its handling in challenging conditions. During this phase, refinements were made to enhance short-field operations, including optimization of the high-lift devices like full-span flaperons to improve low-speed lift without compromising structural integrity. The program also addressed integration of the unpressurized cabin and cargo configurations, ensuring compliance with transport category standards. The final dimensions of the Short 330, refined through testing, included a of 22.78 meters and a fuselage length of 17.69 meters, providing greater capacity over the Skyvan while maintaining its utilitarian profile. These modifications extended the aircraft's range and potential, with the accumulating sufficient flight hours to validate the design before production tooling. Certification efforts culminated in the UK (CAA) awarding a for full Transport Category operations on 18 February 1976, following successful demonstration of airworthiness requirements. The US (FAA) granted its shortly thereafter in September 1976, which facilitated market access in and confirmed the aircraft's suitability for commuter and regional operations. This dual paved the way for the Short 330's entry into service without major redesigns.

Production

Production of the Short 330 took place at ' facility in , , from 1974 to 1992, resulting in a total of 141 built, including 68 examples of the initial 330-100 variant and 73 of the improved 330-200 model. The manufacturing process involved an for key components such as fuselages, wings, and tail units, with integration of Canadian-sourced engines and British systems. Production peaked at a rate of four to five per month during the late , reflecting strong initial demand for regional . A significant upgrade during the production run came with the introduction of the 330-200 variant, which featured more powerful PT6A-45R engines to enhance hot-and-high performance and allow for a higher . Sales were primarily directed to operators in and , accounting for over 75% of deliveries, with limited international partnerships focused on direct exports rather than local assembly agreements. Production of the Short 330 ended in 1992 amid a market shift toward more efficient and the company's focus on developing the larger successor, compounded by broader economic challenges including reductions in aerospace funding.

Operational history

Introduction to service

The Short 330 entered commercial passenger service on August 24, 1976, with Time Air, a Canadian commuter , operating the aircraft on regional routes in , including flights from to and , typically carrying up to 30 passengers. This marked the type's debut as a modern designed for short-haul operations, leveraging its Short Skyvan heritage for reliable performance on unpaved or short runways. Early adoption was swift among commuter airlines in North America and Europe, where the Short 330 filled a niche for routes under 500 km, replacing aging piston-engine aircraft like the de Havilland Canada DHC-6 Twin Otter. Operators praised its low noise levels, achieved through five-bladed Hartzell propellers on Pratt & Whitney Canada PT6A engines, and significantly lower operating costs compared to small jets, enabling economical service in noise-sensitive areas. By 1977, following UK and US certification, orders flowed in from carriers such as Loganair in the United Kingdom, contributing to a fleet expansion that saw dozens of Short 330s in service worldwide by 1980. In its initial role, the Short 330 operated primarily as a 30-seat high-density or in a 19-seat commuter configuration with more spacious seating and amenities, suiting demand for flexible, all-weather connectivity in remote areas. Market reception highlighted its rugged construction and capabilities, which proved effective in adverse weather conditions common to northern latitudes, though it faced growing competition from contemporaries like the and the emerging 1900.

Evolution to cargo operations

During the , the Short 330 underwent a significant transition from passenger to cargo operations, as commuter airlines repositioned their fleets toward regional jets and larger turboprops in response to and intensifying competition from . This shift was driven by the growing demand for efficient small-package delivery in the expanding parcel services sector, leading to increased freighter conversions of existing airframes. Key to this evolution were modifications such as the Sherpa freighter variant, which incorporated a full-width rear and hydraulically operated ramp for streamlined loading and unloading, along with reinforced cabin floors equipped with lashing points to secure payloads up to 3,220 kg. Additional adaptations included quick-change interiors that allowed for flexible reconfiguration between passenger and freight layouts, making the aircraft well-suited for feeder services to major hubs operated by parcel carriers like UPS and . Military adoption, including the U.S. C-23 Sherpa variants in the early , further demonstrated its versatility before the broader shift to civilian roles. These enhancements leveraged the Short 330's short takeoff and landing () capabilities, enabling operations on unpaved runways and in challenging environments. As of March 2025, approximately 14 Short 330s remain active worldwide, almost exclusively in small-package cargo applications that support remote and regional logistics networks, particularly in and . Operators such as continue to utilize the type for short-haul routes, capitalizing on its reliability for time-sensitive deliveries. Despite an average age exceeding 40 years, ongoing viability is supported by aftermarket services from , which provides technical publications, spare parts, and maintenance guidance for the SD3 series. The aircraft's economic appeal persists through low acquisition costs for used examples—typically under $1 million due to their status—and operational efficiency, with lower fuel consumption compared to larger cargo jets, making it cost-effective for niche, low-volume routes. This combination ensures the Short 330's niche role in global cargo ecosystems, even as newer regional freighters emerge.

As of 2025, approximately 14 Short 330s remain in active service, primarily as freighters, representing a significant reduction from the original production run of 136 aircraft, with deliveries from 1976 to 1992 due to attrition from scrapping and accidents during the 2010s. Some airworthy examples are maintained in storage across the United States and Canada, often by cargo operators for potential reactivation or as sources of serviceable components. In Canada, Air Labrador stores at least one Short 330-300(F) (registration C-FLAC) as a non-active asset since 1998. Non-display wrecks and recoverables include several accident-damaged fuselages repurposed for parts recovery, though no major restoration initiatives have been documented. The 2017 crash of N334AC, a Short 330-200 operated by , resulted in the being destroyed, with surviving components likely salvaged for spares by operators facing ongoing needs. Preservation of these stored airframes is challenged by parts sourcing, as operators depend on dwindling legacy stocks from and specialized aftermarket suppliers for critical components like and . This has led to increased reliance on conversions and upgrades in some cases to align with standards, enhancing longevity for select survivors. Looking ahead, surviving Short 330 airframes may see repurposing opportunities, such as conversions for roles, amid broader trends in adapting legacy turboprops for specialized missions.

Its supports a maximum speed of 350 km/h and a cruise speed of 300 km/h (economy) at 3,000 m altitude, with a never-exceed speed of 463 km/h to ensure structural integrity during high-speed maneuvers. Under standard ISA conditions, the achieves a range of 1,040 km with full and a 45-minute fuel reserve, while its ferry range extends to 2,778 km with auxiliary tanks. The service ceiling reaches 6,100 m, complemented by a sea-level of 366 m/min, allowing efficient ascent in varied operational environments. STOL characteristics are highlighted by a takeoff field length of 1,160 m and field length of 1,100 m at under (ISA) conditions, with ground roll distances of approximately 549 m for takeoff and 518 m for . The stall speed is 117 km/h with flaps extended, providing a safety margin during low-speed approaches. Typical endurance for cargo missions stands at 4.5 hours, supporting extended utility in logistics roles.
