Short 360
The Short 360 is a commuter aircraft that was built by Northern Irish manufacturer Short Brothers during the 1980s. The Short 360 seats up to 39 passengers and was introduced into service in November 1982. It is a larger version of the Short 330.
Development
During the 1970s the world's commuter airline market began to evolve from the 20-seat class to larger and more comfortable cabins. Short Brothers of Northern Ireland had created the Skyvan in 1962, followed by the related but larger Short 330 in 1974.The Short 360 development was announced in 1980, with the prototype's first flight on 1 June 1981 and type certification awarded on 3 September 1981.
The first production Short 360 had its maiden flight on 19 August 1982 and entered service with Suburban Airlines in November 1982.
After initiating production with the basic model, Short marketed a number of 360 developments. First was the 360 Advanced, in late 1985, with 1,424 shp PT6A-65-AR engines. That was followed by the 360/300, in March 1987, with six-blade propellers, more powerful PT6A-67R engines, and aerodynamic improvements, giving a higher cruise speed and improved "hot and high" performance. The 360/300 was also built in 360/300F freighter configuration.
Production of the 360 ceased in 1991 after 165 deliveries.
Design
The Short 360 is a 36-seat derivative of the 30–33 seat Short 330. In high density configuration, 39 passengers could be carried. The two Short airliners have a high degree of commonality and are very close in overall dimensions. The later 360 is easily identified by a larger, swept tail unit mounted on a revised rear fuselage. The 360 has a 3'0" fuselage "plug" which gave sufficient additional length for two more seat rows, while the extra length smoothed out the aerodynamic profile and reduced drag. Seating is arranged with two seats on the starboard side of the cabin and one seat on the port side. The 360's power is supplied by two Pratt & Whitney PT6A-65Rs.Building on the strengths and reputation of its 330 antecedent, the 360s found a niche in regional airline use worldwide, being able to operate comfortably from 4,500 ft runways – opening up hundreds of airfields that would otherwise be inaccessible to airliners. With a cruise speed about 215 mph, at an altitude of 10,000 ft, the unpressurized 360 was not the fastest turboprop in its market but it offered acceptable performance at a reasonable price combined with ease of service and maintainability. The PT6A turboprops are fully ICAO Stage 3 noise-compliant, making the 360 one of the quietest turboprop aircraft operating today.
Variants
- 360-100 - the first production model with Pratt & Whitney Canada PT6A-65R turboprop engines.
- 360 Advanced - with PT6A-65AR engines rated at 1,424 shp each. The aircraft was later redesignated 360-200. Introduced in late 1985.
- - with more powerful PT6A-67R engines with six-blade propellers. Higher cruise speed and improved performance.
- 360-300F - the freighter version of the -300, with capacity for five LD3 cargo containers.
- Short C-23 Sherpa B+ and C variants are military-configured Short 360s operated by the United States military. Twenty-eight C-23B+ were produced by conversions of civilian Short 360 airframes, and the C-23C was a conversion of C-23B and C-23B+.

- 5 February 2006: Two Short 360-300 freighters, modded for a DOD contract, operated by Air Cargo Carriers, were flying in formation when they collided near Watertown, Wisconsin, US. N3735W attempted to maneuver below N372AC in a right turn and struck the left/ underside of N372AC. The left wing outer section of N3735W was struck and separated by the leading edge of N372AC's left wing, and the aircraft crashed, killing all three occupants. The left propeller of N3735W had struck the forward section of the left "stub wing" of N372AC. N372AC sustained severe damage, including structural, engine, propeller, aerodynamic, and complete hydraulic failure. The crew managed to make an emergency landing at Dodge County Airport in Juneau, WI, but overran the runway due to the damage to the aircraft. The left aileron of N3735W was found on the runway that N372AC landed on. Both crewmen survived uninjured, but N372AC was damaged beyond reasonable repair.

There were no injuries to the flight crew of two. The airplane was 60 pounds over Max. takeoff weight and during the long taxi to position for takeoff the crew used a higher than normal power setting and rode the brakes in an attempt to lower weight by burning fuel. Its intended destination was Austin, Texas.
