Hawker Siddeley HS 748
The Hawker Siddeley HS 748 is a medium-sized turboprop airliner originally designed by the British firm Avro in the late 1950s as a replacement for the aging DC-3s then in widespread service as feederliners. Avro concentrated on performance, notably for STOL operations, and found a dedicated market. 380 aircraft were built by Hawker Siddeley. A larger, stretched development of the HS 748, the BAe ATP, attempted to compete with the de Havilland Canada Dash 8but saw a limited production run.

Accidents and incidents
- On 10 July 1965, Avro 748-101 Series 1 G-ARMV of Skyways Coach-Air was written off in a landing accident at Lympne Airport. The 51 people on board survived. This was the first accident that resulted in a write-off on an Avro 748 / HS748.
- On 15 August 1967, two accidents involving HS-748-222 Series 2 aircraft of Channel Airways Limited, occurred roughly 90 minutes apart at Portsmouth Airport. In the first incident, G-ATEK, operating a scheduled service from Southend to Paris, via Portsmouth, landed in rainy conditions and was unable to stop in the available distance on the grass runway. The aircraft slid sideways, left the runway and stopped on an embankment. Some 90 minutes later, aircraft G-ATEH, operating a scheduled service from Jersey, via Guernsey to Portsmouth, landed and slid on the runway, crashed through a perimeter fence and came to rest on the main Eastern Road. There were no injuries in either accident, but both aircraft sustained serious damage. An AIB investigation[4] reported that "both accidents were caused by inadequate braking which had resulted from the extremely low coefficient of friction provided by the very wet grass surface over the hard, dry and almost impermeable sub-soil".
- On 4 February 1970, Aerolíneas Argentinas Flight 707, an Avro 748-105, crashed into the ground after the pilots lost control of the aircraft. The aircraft crashed at Loma Alta, Argentina and killed all 37 on board.
- On 9 December 1971, Indian Airlines, an HS 748, near Chinnamanur was descending into Madurai when it flew into high terrain about 50 mi (80 km) from the airport, killing the four crew members and 17 passengers. There were ten survivors among the passengers. The accident occurred in reduced visibility during daylight hours.[5][6][7]
- 20 January 1976 – a TAME HS 748-246 Series 2A registration HC-AUE crashed while flying over mountainous terrain at 10,000 feet. The aircraft struck trees with its right wing, lost control and crashed into the side of the mountain. The plane was en route from Loja to Simón Bolívar International Airport in Guayaquil, Ecuador. Six crewmembers and 28 passengers were killed; 8 passengers survived.

- 31 July 1979 at Sumburgh Airport in the Shetland Islands, Scotland; Dan-Air Flight 0034, an HS 748 series 1 (registration G-BEKF) operating an oil industry support flight crashed. The aircraft failed to become airborne and crashed into the sea. The accident was due to the elevator gust-lock having become re-engaged, preventing the aircraft from rotating into a flying attitude. The aircraft was destroyed and 17 persons died from drowning.
- 22 August 1979 – An aircraft mechanic (a former non-commissioned officer of the Colombian Air Force), stole a military HS 748 (FAC-1101) from a military hangar at the Eldorado International Airport in Bogotá, Colombia. According to the news, this person stole the aircraft with the intention of crashing it against his parents' house. After some minutes in the air, it ran out of fuel and crashed, killing the impromptu pilot and three people on the ground.[8]
- On 26 June 1981, Dan-Air Flight 240, an HS 748 2A mail flight from Gatwick Airport to East Midlands Airport crashed at Nailstone killing the 3 crew members. While descending, the right-hand rear door detached, struck the horizontal tail plane and became lodged on its leading edge. Control was lost, and the aircraft entered a steep dive. During the dive, the wings and tail plane failed due to overstressing.
- On 19 August 1981, Indian Airlines Flight 557, an HAL 748 (VT-DXF) overshot the runway at Mangalore-Bajpe Airport in wet weather. The aircraft came to a halt just beyond the runway edge. There were no fatalities but the damaged aircraft was written off. One of the passengers on board was Veerappa Moily ex-Cabinet Minister for Law, Justice and Company Affairs in the Government of India.[9][10]
- 11 October 1983 – Air Illinois Flight 710carrying 10 people crashed at night in a thunderstorm between Pinckneyville and Tamaroa, IL. The flight originated at Chicago's Meigs Field and had stopped at Springfield, IL. The left generator had failed after takeoff and the first officer had mistakenly isolated the right generator. Attempts to restore the right generator were unsuccessful. The captain elected to continue to the destination rather than return to the nearby airport. The cloud base was at 2000 feet MSL, but ATC could not provide an IFR below 3,000 feet just before the crash. The crew indicated a total loss of electrical power. The left generator drive shaft had sheared.[11] All ten passengers and crew were killed.[12]
- 27 June 1987 – Philippine Airlines Flight 206 crashed onto a mountain after poor visibility hampered the pilot's attempt to land at Loakan Airport in Baguio City, Philippines. All 50 passengers and crew were killed.
- 29 April 1995 – Sri Lanka Air Force Avro 748 CR835 an HS 748 serial CR835 (4R-HVB) was hit by an SA-7 missile fired by the LTTE while on approach to Palaly/KKS/Jaffna. All 52 occupants on board were killed.[13]

All 10 passengers and 5 crew were killed.
- 1 June 2002[14] – Former South African cricket captain Hansie Cronje's scheduled flight home from Bloemfontein to Georgehad been grounded, so he hitched a ride as the only passenger on a cargo flight in an HS 748. Near George airport, the pilots lost visibility in cloud, and were unable to land, partly due to unserviceable navigational equipment. While circling, the plane crashed into the Outeniqua mountains northeast of the airport. Cronje, aged 32, and the two pilots died. South Africa's High Court reached the conclusion that "the death of the deceased Wessel Johannes (Hansie) Cronje was brought about by an act or omission prima facie amounting to an offence on the part of pilots."[15][16]However, with Cronje's involvement in match-fixing, theories that Cronje was murdered on the orders of a cricket betting syndicate flourished after his death.[17]
- 12 June 2012[18] – A Wasaya AirwaysHawker-Siddley 748 caught fire during ground operations at Sandy Lake First Nation in Northwestern Ontario. No injuries were reported. The aircraft burned completely; only the left wing and nacelle survived.
