Bristow Helicopters Limited is a British civil helicopter operator originally based at Aberdeen Airport, Scotland which is now part of the U.S. based Bristow Group (NYSE: BRS, S&P 600 component) which in turn has its corporate headquarters in Houston, Texas.
Bristow Helicopters Limited holds a United Kingdom Civil Aviation Authority Type A Operating Licence, it is permitted to carry passengers, cargo and mail on aircraft with 20 seats or more. The U.S. division of Bristow is a Federal Aviation Administration (FAA) approved Part 135 air carrier.
Bristow Helicopters Limited was established in June 1955 by Alan Bristow.
In 1996, Bristow Helicopters was purchased by Offshore Logistics, an American offshore helicopter operator which operated as Air Logistics in the U.S. Gulf of Mexico and Alaska, and was structured as a reverse takeover. The group now operates and maintains a global fleet of over 400 aircraft. In 2006 Offshore Logistics re-branded itself as 'The Bristow Group'.
The Bristow Group expanded their portfolio in April 2007 with the purchase of Helicopter Adventures, a Florida-based flight school, Helicopter Adventures was subsequently renamed Bristow Academy. The deal also provided the Bristow Group with the world's largest civilian fleet of Schweizer aircraft.
Bristow (formerly Air Logistics)
In January 2010, Bristow announced the retirement of the Air Logistics name and Gulf of Mexico operations would operate under the name Bristow. Bristow provides helicopter services, maintenance and other support services to the oil and gas industry. It operates more than 170 single and twin-turbine helicopters in the United States. These receive support, materials and operational assistance from its regional headquarters and primary maintenance facility located at the Acadiana Regional Airport in New Iberia, Louisiana.
Eastern Airways and Airnorth
Fixed Wing Bristow has controlling interests in Eastern Airways which is a regional airline based in the U.K. operating fixed wing regional jet and turboprop aircraft and Airnorth, also a regional airline, based in Australia operating fixed wing regional jet and turboprop aircraft. Both Eastern Airways and Airnorth operate scheduled passenger services, shuttle flights for oil and gas industry personnel, and charter services.
In addition to its wholly owned international operations, Bristow Group maintains service agreements and equity interests in helicopter operators in Brazil, Canada, Colombia, Egypt, Kazakhstan, Turkmenistan, Mexico, Norway and Russia (Sakhalin) and the United Kingdom. This allows Bristow to extend its range of services into new and developing oil and gas markets and helps provide a lower cost structure in some operating areas. Partners include:
- Cougar Helicopters
- Helicopteros Nacionales de Colombia, Helicol S.A., Colombia
- Petroleum Air Services, Egypt
- Atyrau Bristow Airways Services (ABAS), Kazakhstan
- Turkmenistan Helicopters Limited, Turkmenistan
- Heliservicio Campeche, Mexico
- Norsk Helikopter, Norway - now Bristow Norway
- Sakhalin Bristow Air Services AKA Aviashelf, Sakhalin, Russia
- FBH Limited, UK
Although not a joint venture, in 2015 Bristow and AgustaWestland agreed to develop offshore and search and rescue capabilities for the AW609 tiltrotor. This could simplify a typical trip from Clapham Common to an oil rig by using just one aircraft. Bristow intends to order more than 10 tiltrotors.
The Search and Rescue Training Unit at RAF Valley is a detachment of the Defence Helicopter Flying School at RAF Shawbury, from which its aircraft are distinguished by their flotation bags, rescue winches and cable cutters above the cockpit roof. The aircraft are maintained to EASA standards but are military registered allowing them to operate outside civilian flight restrictions.
All the Defence Helicopter Flying School Helicopters and Synthetic Training Equipment are owned by FB Heliservices, a consortium of Bristow Helicopters and FR Aviation, who provide 40% of the instructional staff, all the ground school and simulator staff, carry out all maintenance and provide support services.
Search and Rescue
Bristow helicopters operated Sikorsky S-61N helicopters on behalf of Her Majesty's Coastguard, the United Kingdom's Coast Guard, until July 2007 after which there was a 12-month transitional period whilst CHC Helicopter took over the contract replacing the S-61N with new helicopters.
Bristow operated four dedicated Search and Rescue (SAR) sites in the UK, on behalf of the Coast Guard Service. The units were located at Portland (EGDP) and Lee-on-Solent (EGHF) on the south coast of England, at Stornoway (EGPO) in the Outer Hebrides, and at Sumburgh (EGPB) in the Shetland Isles.
On 26 March 2013 Bristow was awarded a 10-year contract to operate the search and rescue operations in the United Kingdom, at the time being provided by CHC Helicopter (on behalf of Her Majesty's Coastguard), the Royal Air Force and the Royal Navy. Bristow is currently operating AgustaWestland AW139 and Sikorsky S-92 helicopters in support of this contract. They were originally planning on using AgustaWestland AW189 helicopters but the procurement programme has been delayed, resulting in AAR AIrlift Group claiming the first civilian registered SAR AW189, based in the Falkland Islands, in support of the UK Government 
Bristow operates a large fleet of over 450 helicopters and aircraft, which includes unconsolidated affiliates and joint venture partners. Bristow intends to reduce fleet variety from 24 helicopter types to six. For subsidiaries Eastern Airways and Airnorth fixed wing jet and turboprop aircraft, see Eastern Airways and Airnorth.
- 5N-ABQ, a Scottish Aviation Twin Pioneer Srs1, crashed on 4 April 1967 in Nigeria during a single engine approach.
- G-ASWI North Sea ditching - On 13 August 1981 a Westland Wessex 60 helicopter lost power to the main rotor gearbox, going out of control during the ensuing autorotation. The flight was carrying 11 gas workers from the Leman gas field to Bacton, Norfolk. All people on board were lost.

- On 4 July 1983, Bristow Helicopters AS332L Super Puma (G-TIGD) crashed on landing at Aberdeen. During the approach to Aberdeen from the North Hutton platform, a loud bang was heard, followed by severe vibration. A PAN call was made to ATC by the crew. Shortly before landing control was lost and the helicopter struck the runway heavily on its side. 10 of 16 passengers received serious injuries. A tail boom panel had become detached in flight and damaged all five tail rotor blades. The resulting imbalance to the tail rotor assembly led to the separation of this unit and subsequent loss of control.
- G-BJJR a Bell 212 that crashed with the loss of two crew on approach to the Cecil Provine in 1984.
- VR-BIG Aerospatiale SA-330J Puma 5 December 1991 in Mermaid Sound, Dampier, Western Australia, after a pick-up from departing LNG tanker in night VFR conditions, entered vortex ring state and ditched. Stayed afloat for over 2 hrs.

- G-BJVX North Sea Crash - G-BJVX, a commercial Sikorsky S-76A helicopter operated by Norwich-based Bristow Helicopters, crashed in the evening of 16 July 2002 in the southern North Sea while it was making a ten-minute flight between the gas production platform Clipper and the drilling rig Global Santa Fe Monarch, after which it was to return to Norwich Airport. The 22-year-old helicopter was flying at an altitude of about 320 feet (98 m) when workers on the Global Santa Fe Monarch heard "a loud bang". No witnesses were actually watching the aircraft at the time, but some saw it dive steeply into the sea. A witness also reported seeing the helicopter's rotor head with rotor blades attached falling into the sea after the body of the helicopter had impacted. The accident caused the death of all those on board (two crew members and nine Shell workers as passengers). The body of the eleventh man has never been recovered.
