Overview
CHC Helicopter is a Canadian-founded multinational helicopter services company whose principal activities include offshore transportation, search and rescue, emergency medical support, government aviation, and helicopter maintenance, repair, and overhaul. Although its corporate headquarters are in Irving, Texas, the company is incorporated in Newfoundland and Labrador and developed from the postwar commercial helicopter industry in British Columbia. The company’s origins reach back to Okanagan Air Services, established in the late 1940s by former Royal Canadian Air Force personnel Carl Agar, Barney Bent, and Alf Stringer. The business initially conducted fixed-wing charter and training work, but expanded into helicopters after acquiring a Bell 47 in 1947. Its early missions included crop spraying, mountain surveying, remote construction support, transportation of personnel and equipment, and government work. During the 1950s the company became known as Okanagan Helicopters and grew rapidly through contracts connected with remote infrastructure, including the Mid-Canada Line radar network. Okanagan expanded throughout Canada during the 1960s and 1970s and began taking international contracts. It also acquired numerous regional helicopter operators and transitioned from piston-powered aircraft toward turbine helicopters such as the Bell 204, Bell 212, Sikorsky S-58T, Sikorsky S-62, and Sikorsky S-76. By the early 1980s it was Canada’s largest helicopter operator, with a substantial fleet, a large workforce, and significant revenue from domestic and international contracts. A major turning point came in 1987, when Newfoundland businessman Craig Dobbin led investors organized as Canadian Holding Company, or CHC. CHC combined Okanagan Helicopters, Viking Helicopters, Toronto Helicopters, and Dobbin’s Sealand Helicopters interests into a new operating structure initially branded Canadian Helicopters, while the parent organization became CHC Helicopter Corporation. The group pursued an acquisition-led international strategy, buying or integrating operators in the United Kingdom, Norway, Australia, South Africa, the Netherlands, and other markets. These acquisitions made CHC a significant global contractor in offshore oil and gas aviation. The group reorganized its activities in 2004 into two principal divisions. Helicopter Services focused on flight operations, while Heli-One became a specialized independent provider of helicopter maintenance, repair, and overhaul services. The corporate headquarters moved from St. John’s, Newfoundland and Labrador, to Richmond, British Columbia, before later being established in Irving, Texas. First Reserve acquired all CHC shares in 2008, and the company adopted the shorter CHC Helicopter name. CHC subsequently pursued a public offering, but declining oil prices, weaker offshore activity, and a heavy debt burden placed the business under severe financial pressure. Its shares were delisted from the NYSE in February 2016, and the company filed for Chapter 11 bankruptcy in May 2016. The restructuring allowed CHC to reject or shed aircraft-related obligations and led to a new ownership structure dominated by creditors. CHC emerged from bankruptcy in March 2017 with a relaunched brand and web presence. CHC’s business remains concentrated in technically demanding and safety-critical operations. Its customers and partners have included offshore energy companies, governments, coast guards, armed forces, police agencies, ambulance services, and offshore wind developers. Its international activities have included crew-change flying in the North Sea and the United Kingdom, search and rescue in Norway and Svalbard, emergency and military support in Australia, and long-running coast guard aviation in Ireland. Through Heli-One, the company also provides maintenance and overhaul capabilities for a range of commercial and government helicopter fleets.
History
CHC Helicopter developed from the commercial aviation businesses created in British Columbia after the Second World War. Former Royal Canadian Air Force instructors Carl Agar and Barney Bent established a flight-training club in Penticton, later joined by engineer Alf Stringer. The business moved to Kelowna and became Okanagan Air Services. Initially it operated fixed-wing aircraft for charter and training work. The founders soon recognized the commercial potential of helicopters. In 1947 the company acquired a Bell 47-B3, which became the first commercially licensed helicopter in British Columbia. Early work included crop and insect spraying, mountain surveying, and support for remote construction projects. The company’s mountain flying and surveying activities generated government and industrial contracts, although profitability was initially limited. During the early 1950s the company adopted the Okanagan Helicopters name and expanded rapidly. It supported construction and maintenance of the Mid-Canada Line radar stations with Sikorsky and Bell helicopters. By the end of the decade it operated dozens of aircraft across Canada. It continued expanding through the 1960s, taking its first overseas contract in East Pakistan in 1963 and building a broader presence in remote infrastructure and resource work. The 1970s brought both consolidation and technological change. Okanagan acquired a succession of Canadian operators, created an international division, and introduced turbine-powered helicopters that offered greater capability than the piston aircraft used in its earlier operations. By 1981 it had become Canada’s largest helicopter company. Its scale attracted outside investors, including Resource Service Group and Alan Bristow, the founder of Bristow Helicopters. In 1987 Craig Dobbin led an investor group known as Canadian Holding Company. CHC combined Okanagan Helicopters with Viking Helicopters, Toronto Helicopters, and Sealand Helicopters. The resulting group initially used the Canadian Helicopters operating name, while the parent company became CHC Helicopter Corporation. The company thereafter emphasized acquisitions and partnerships as a route into new territories and underdeveloped helicopter markets. CHC expanded internationally during the 1990s and 2000s. Important transactions included British International Helicopters, Helicopter Services Group of Norway, Bond Helicopters, Helikopter Service, Lloyd Helicopters of Australia, Court Helicopters of South Africa, and Schreiner Aviation Group. These transactions helped establish CHC as a major offshore oil-and-gas helicopter contractor across several continents. In 2000, CHC reached an arrangement involving Fonds de Solidarité FTQ and management of its Canadian divisions that separated significant Canadian operating interests into Canadian Helicopters. In 2004 CHC reorganized into Helicopter Services and Heli-One. Helicopter Services managed international flight operations, while Heli-One focused on independent maintenance, repair, and overhaul. The corporate headquarters moved from St. John’s to Richmond, British Columbia, and later to Irving, Texas. First Reserve acquired CHC in 2008. Around the same period the company shortened its name to CHC Helicopter. The company pursued a public listing in the following decade, but the offshore energy downturn after the collapse in oil prices placed pressure on revenue. High leverage compounded the problem. CHC’s shares were delisted from the NYSE in February 2016, followed by a Chapter 11 filing in May. During the restructuring it shed substantial aircraft obligations, including many associated with its Super Puma fleet. CHC emerged in March 2017 with creditors holding majority ownership and with a refreshed brand identity. After restructuring, CHC continued operating as a specialist provider for offshore energy, search and rescue, emergency medical services, military and government aviation, and helicopter maintenance. Its operations have included United Kingdom offshore crew transport, Norwegian and Svalbard search and rescue, Australian emergency and defense support, Irish Coast Guard aviation, and support for offshore wind development. The company’s operating model remains based on combining aircraft, crews, maintenance expertise, and regulatory capability for customers working in remote or safety-critical environments.
