The H-92 Superhawk is a military version of the S-92 in the utility transport role, capable of carrying 22 troops. The H-92 can also be configured for specific missions, including search and rescue and executive transportation. The CH-148 Cyclone is a shipboard maritime helicopter variant developed for the Royal Canadian Air Force to support naval operations of the Royal Canadian Navy. The Sikorsky VH-92 is a variant under development to replace the United States Marine Corps' Marine One U.S. Presidential transport fleet.

Development edit

After the 1973 oil crisis, major oil and gas companies began exploration further offshore, thus creating a need for aircraft such as the S-92 with sufficient capability.[2]

Sikorsky Aircraft first displayed a S-92 mockup of the planned helicopter in 1992. The S-92 was to be offered for sale beginning in 1993, but due to a decline in the international market for helicopters, this was delayed. In 1995 Sikorsky formed Team S-92 with international partners and launched the helicopter program at the Paris Airshow that year.[3] Sikorsky developed the S-92 to compete with civil aircraft such as the Aerospatiale/Eurocopter Super Puma.[4] The helicopter uses a new airframe with dynamic components based on the S-70/H-60 components. The S-92 took its maiden flight on December 23, 1998 at the Sikorsky Development Flight Center, West Palm Beach, Florida.[4][5]

In July 2000, Sikorsky announced design changes to the S-92. The fuselage of prototype #3 was lengthened by 16 in (40 cm) aft of the cockpit, the tail pylon was shortened by 41 in (1.04 m), and the horizontal stabilizer was repositioned from the left side opposite the tail rotor to the right side at the base of the tail pylon. The modifications to the tail solved a pitch stability issue discovered during flight testing, and were reported to allow the aircraft to meet a key requirement of the Nordic Standard Helicopter Program (NSHP) for shipboard stowage. The lengthening of the fuselage and shortening of the tail pylon shifted the aircraft center of gravity (CG) forward, permitting a more level attitude in flight. The longer fuselage allowed for an additional row of three seats, as well as a larger passenger door option for Search and Rescue (SAR) customers. Sikorsky incorporated the changes into the following two prototypes as the production standard configuration.[6] Some reports suggested that the modifications were actually to resolve damage from structural design flaws.[7]

The S-92 is built and customized in Sikorsky's Coatesville, Pennsylvania facility. The S-92 received Federal Aviation Administration (FAA) part 29 type certification on December 19, 2002,[8] and received International European Aviation Safety Agency/Joint Aviation Authorities (EASA/JAA) certification on June 8, 2004.[9] In June 2009, Sikorsky Aircraft entered into a joint-venture with Tata Advanced Systems for S-92 manufacturing in India for export and domestic markets. A US$200 million manufacturing plant will be operational in Hyderabad by 2010. Initially, TASL will supply the complete cabins for the S-92 to Sikorsky.[10][11] The first cabin was delivered in November 2010.[12]

Design edit

The S-92 is multi-purpose helicopter powered by twin GE CT7-8A turboshaft engines and has an aluminum airframe and some composite components. The four-bladed fully articulated composite main rotor blade is wider and has a longer radius than the Sikorsky S-70. The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Most of the rotor system components aside from the blades are titanium.[citation needed]

The S-92 features an active vibration control system, using vibration sensors and structurally mounted force generators to increase flight comfort and lower acoustic levels to below certification requirements.[13] A 2008 study by Norway's Flymedisinsk Institute found that the S-92's vibration levels were 42 percent above that of the Eurocopter EC225 Super Puma; Sikorsky disputed this finding, saying that the study hadn't used their latest anti-vibration technology.[14] In February 2011, as published on a Norwegian newspaper's website, the noise and vibration levels were reportedly subject to health concerns, allegedly causing tinnitus and heart problems.[15][16]

A number of safety features such as flaw tolerance, bird strike capability, and engine burst containment have been incorporated into the design. Adherence to FAA FAR part 29 has led the FAA certification board to call the S-92 the "safest helicopter in the world".[17] The S-92 was not able to meet the Federal Aviation Regulation "run dry" specification for loss of oil pressure in the main gearbox, but was certified with an exemption due to the unlikelihood of such a situation occurring; this was a factor in the fatal crash of Cougar Helicopters Flight 91 in 2009.[18]

Operational history edit

The S-92 received FAA certification in 2002,[8] and International certification in June 2004.[9] The first S-92 was delivered in late 2004 to launch customer PHI, Inc.[19][20]

Competitions edit

Sikorsky entered a Search and rescue variant of the H-92 in U.S. Air Force's CSAR-X combat search and rescue competition beginning in 2006. Its competitors were the AgustaWestland EH101 and HH-47, but by December 2012 all other manufacturers had withdrawn.[21] Flight International magazine expects Sikorsky to bid a version of its MH-60 special operations helicopter.[22]

After Sikorsky successfully challenged in court the preferred supplier status of NHIndustries NH90 for the Nordic Standard Helicopter Programme an open competition was held.[23] Sikorsky entered the S-92 as a candidate for the Norwegian All Weather Search and Rescue Helicopter (NAWSARH) that is planned to replace the Royal Norwegian Air Force Westland Sea King Mk.43B in 2015.[24] The other candidates for the NAWSARH contract of 10 to 12 helicopters were AgustaWestland AW101, Bell Boeing V-22 Osprey, Eurocopter EC225, and NHIndustries NH90.[25] The V-22 was eliminated from the competition in 2012.[26] The S-92 was removed from the competition in July 2013 and was subsequently won by AgustaWestland with an order for 16 AW101s.[23]

The S-92 competed with the Eurocopter EC225 for the UK Search and Rescue – Helicopter (SAR-H) program.[27] In February 2010, the S-92 was selected by the UK in a £6bn deal to replace 40 Sea King search and rescue helicopters with 25 to 30 S-92s;[28] it subsequently announced that Soteria, the preferred supplier, will not be used due to irregularities with its bid.[29] The UK government subsequently opted for a smaller £2.5bn contract with the Bristow Group to operate 11 S-92s (and 11 AW189s) from 10 bases.[30]

The Irish Coast Guard replaced its Sikorsky S-61N fleet with the S-92, beginning in 2012. The aircraft are operated by CHC Helicopter.[31]

In the wake of the deadly 2016 crash of a Eurocopter EC225 Super Puma contracted by Statoil, that company announced that it would not use that type again and instead use the Sikorsky S-92 to meet its needs, stipulating that operators it contracts with, such as CHC Helikopter Service, will be required to use such equipment.[32]

Variants edit

S-92A edit

The S-92A is the civilian variant and is available in a number of versions. The civil transport version has an airliner-type interior that seats 19 passengers. The utility transport version has 22 side-facing seats with a full cabin width rear ramp. The 733 sq ft (68.1 m2) interior cabin area can also be configured to accommodate up to three airline-style LD3 cargo containers. Additional stowage space is available in the 140 sq ft (13 m2) area located in the aft ramp compartment. During development it was referred to as the S-92C Helibus.

H-92 Superhawk edit

The H-92 Superhawk is the military variant of the S-92. It has been demonstrated to the U.S. Air Force, Marine Corps and Coast Guard. The H-92 has more powerful GE CT7-8C engines, rated at 3,070 shp (2,290 kW) and, unlike the S-92, has fly-by-wire flight controls. The search and rescue variant provides space for seats, litters, auxiliary fuel cell and SAR emergency equipment.

In July 2004, the H-92 Superhawk was selected by Canada for its Maritime Helicopter Programme (MHP) as the CH-148 Cyclone. Canada ordered 28 helicopters in November 2004.[33] The program has been delayed multiple times.[34] As of November 2019, nineteen CH-148 Cyclones have been built, delivered, and accepted by the government of Canada. The Canadian military declared initial operational capacity in June 2018, and expects full operational capacity by 2022.[35]

VH-92 edit

Notable accidents and incidents edit

  • On July 2, 2008, an S-92A servicing an oil platform in Australia lost gearbox oil pressure due to fractured oil pump studs and was forced to make an emergency landing.[70] This incident led to Sikorsky issuing a notice to replace titanium gearbox studs with steel studs. This refit had not yet been conducted on the Cougar Helicopters S-92 that crashed the following year.[citation needed]
  • On July 19, 2008, an S-92 carrying Rev. Sun Myung Moon crashed in South Korea.[71] The helicopter was flying in inclement weather that forced it down on a hillside. The 16 people aboard were slightly injured in the crash.[72][73]
  • On March 12, 2009, Cougar Helicopters Flight 91, an S-92A operated by Cougar Helicopters carrying 18 passengers and crew en route to oil platforms off the coast of Newfoundland, crashed and sank in 170 meters (560 ft) of water[74] during an attempted ditching. One person was rescued from the North Atlantic with serious injuries[75] and the others did not survive.[76] The crash was determined[77] to be caused by 16 separate factors. The primary cause was galling or fracture of titanium gearbox studs that had not yet been replaced with steel.[78]
  • On December 28, 2016, a S-92 (registration G-WNSR, serial number 920250[79]) operated by CHC Helicopter experienced "unexpected control responses" whilst in mid-air on a routine shuttle flight between two oil installations in the North Sea. The pilots conducted an emergency landing on the West Franklin platform.[80] The helicopter is reported to have spun on the helideck during the landing, damaging the helicopter wheels and rotor blades.[81] The helideck also sustained damage during the emergency landing.[81] There were no reported injuries amongst the nine passengers and two crew during the incident.[80] The aircraft was transported back to Aberdeen via ship, at which time the Air Accidents Investigation Branch began their investigation into the incident.[82] Sikorsky issued a notice on January 9, 2017 grounding all S-92 aircraft until the tail rotors have been inspected. The inspection work takes approximately 11 man hours to complete.[83] The Air Accidents Investigation Branch issued an update on January 11, 2017 that reported that the tail rotor pitch change shaft bearing had seized. The bearing showed signs of severe overheating and significant wear. The failure of the bearing allowed the tail rotor driveshaft to damage the tail rotor servo. The damage to the tail rotor servo is considered to be the cause of the loss of tail rotor control. The health and usage monitoring systems had discovered the flaw the day before flight, but the maintenance crew had not.[84]
  • On March 14, 2017, a S-92 operated by CHC Helicopter under contract to the Irish Coast Guard crashed off the west coast of Ireland with four crew members on board. Three of the crew were initially missing. Captain Dara Fitzpatrick was recovered from the water but later died in hospital.[85] The helicopter crashed into an unmapped island in poor weather. The helicopter fuselage was located.[86] Captain Mark Duffy's body was recovered in the helicopter's cockpit on March 26.[87]
  • On February 28, 2024, Bristow Group S-92 search and rescue helicopter crashed west of Bergen, Norway with six crew and passengers onboard.[88]

The Sikorsky S 92 is an American twin engine medium lift helicopter built by Sikorsky Aircraft for the civil and military helicopter markets The S 92 was developed from the Sikorsky S 70 helicopter and has similar parts such as flight control and rotor systems S 92 H 92 Superhawk An S 92 of Bristow Helicopters Role Medium lift transport utility helicopter National origin United States Manufacturer Sikorsky Aircraft First flight December 23 1998 Introduction 2004 Status In service Primary users CHC HelicopterPetroleum Helicopters International Bristow Helicopters Cougar Helicopters Produced 1998 present Number built at least 300 1 Developed from Sikorsky S 70 Variants Sikorsky CH 148 Cyclone Sikorsky VH 92 The H 92 Superhawk is a military version of the S 92 in the utility transport role capable of carrying 22 troops The H 92 can also be configured for specific missions including search and rescue and executive transportation The CH 148 Cyclone is a shipboard maritime helicopter variant developed for the Royal Canadian Air Force to support naval operations of the Royal Canadian Navy The Sikorsky VH 92 is a variant under development to replace the United States

crisis major oil and gas companies began exploration further offshore thus creating a need for aircraft such as the S 92 with sufficient capability 2 Sikorsky Aircraft first displayed a S 92 mockup of the planned helicopter in 1992 The S 92 was to be offered for sale beginning in 1993 but due to a decline in the international market for helicopters this was delayed In 1995 Sikorsky formed Team S 92 with international partners and launched the helicopter program at the Paris Airshow that year 3 Sikorsky developed the S 92 to compete with civil aircraft such as the Aerospatiale Eurocopter Super Puma 4 The helicopter uses a new airframe with dynamic components based on the S 70 H 60 components The S 92 took its maiden flight on December 23 1998 at the Sikorsky Development Flight Center West Palm Beach Florida 4 5 In July 2000 Sikorsky announced design changes to the S 92 The fuselage of prototype 3 was lengthened by 16 in 40 cm aft of the cockpit the tail pylon was shortened by 41 in 1 04 m and the horizontal stabilizer was repositioned from the left side opposite the tail rotor to the right side at the base of the tail pylon The modifications to the tail solved a pitch stability issue discovered during flight testing and were reported to allow the aircraft to meet a key requirement of the Nordic Standard Helicopter Program NSHP for shipboard stowage The lengthening of the fuselage and shortening of the tail pylon shifted the aircraft center of gravity CG forward permitting a more level attitude in flight The longer fuselage allowed for an additional row of three seats as well as a larger passenger door option for Search and Rescue SAR customers Sikorsky incorporated the changes into the following two prototypes as the production standard configuration 6 Some reports suggested that the modifications were actually to resolve damage from structural design flaws 7 The S 92 is built and customized in Sikorsky s Coatesville Pennsylvania facility The S 92 received Federal Aviation Administration FAA part 29 type certification on December 19 2002 8 and received International European Aviation Safety Agency Joint Aviation Authorities EASA JAA certification on June 8 2004 9 In June 2009 Sikorsky Aircraft entered into a joint venture with Tata Advanced Systems for S 92 manufacturing in India for export and domestic markets A US 200 million manufacturing plant will be operational in Hyderabad by 2010 Initially TASL will supply the complete cabins for the S 92 to Sikorsky 10 11 The first cabin was delivered in November 2010 12 Design edit nbsp An S 92 at Sola Airport Norway in July 2003 The S 92 is multi purpose helicopter powered by twin GE CT7 8A turboshaft engines and has an aluminum airframe and some composite components The four bladed fully articulated composite main rotor blade is wider and has a longer radius than the Sikorsky S 70 The tapered blade tip sweeps back and angles downward to reduce noise and increase lift Most of the rotor system components aside from the blades are titanium citation needed The S 92 features an active vibration control system using vibration sensors and structurally mounted force generators to increase flight comfort and lower acoustic levels to below certification requirements 13 A 2008 study by Norway s Flymedisinsk Institute found that the S 92 s vibration levels were 42 percent above that of the Eurocopter EC225 Super Puma Sikorsky disputed this finding saying that the study hadn t used their latest anti vibration technology 14 In February 2011 as published on a Norwegian newspaper s website the noise and vibration levels were reportedly subject to health concerns allegedly causing tinnitus and heart problems 15 16 A number of safety features such as flaw tolerance bird strike capability and engine burst containment have been incorporated into the design Adherence to FAA FAR part 29 has led the FAA certification board to call the S 92 the safest helicopter in the world 17 The S 92 was not able to meet the Federal Aviation Regulation run dry specification for loss of oil pressure in the main gearbox but was certified with an exemption due to the unlikelihood of such a situation occurring this was a factor in the fatal crash of Cougar Helicopters Flight 91 in 2009 18 Operational history editThe S 92 received FAA certification in 2002 8 and International certification in June 2004 9 The first S 92 was delivered in late 2004 to launch customer PHI Inc 19 20 Competitions edit Sikorsky entered a Search and rescue variant of the H 92 in U S Air Force s CSAR X combat search and rescue competition beginning in 2006 Its competitors were the AgustaWestland EH101 and HH 47 but by December 2012 all other manufacturers had withdrawn 21 Flight International magazine expects Sikorsky to bid a version of its MH 60 special operations helicopter 22 After Sikorsky successfully challenged in court the preferred supplier status of NHIndustries NH90 for the Nordic Standard Helicopter Programme an open competition was held 23 Sikorsky entered the S 92 as a candidate for the Norwegian All Weather Search and Rescue Helicopter NAWSARH that is planned to replace the Royal Norwegian Air Force Westland Sea King Mk 43B in 2015 24 The other candidates for the NAWSARH contract of 10 to 12 helicopters were AgustaWestland AW101 Bell Boeing V 22 Osprey Eurocopter EC225 and NHIndustries NH90 25 The V 22 was eliminated from the competition in 2012 26 The S 92 was removed from the competition in July 2013 and was subsequently won by AgustaWestland with an order for 16 AW101s 23 The S 92 competed with the Eurocopter EC225 for the UK Search and Rescue Helicopter SAR H program 27 In February 2010 the S 92 was selected by the UK in a 6bn deal to replace 40 Sea King search and rescue helicopters with 25 to 30 S 92s 28 it subsequently announced that Soteria the preferred supplier will not be used due to irregularities with its bid 29 The UK government subsequently opted for a smaller 2 5bn contract with the Bristow Group to operate 11 S 92s and 11 AW189s from 10 bases 30 The Irish Coast Guard replaced its Sikorsky S 61N fleet with the S 92 beginning in 2012 The aircraft are operated by CHC Helicopter 31 In the wake of the deadly 2016 crash of a Eurocopter EC225 Super Puma contracted by Statoil that company announced that it would not use that type again and instead use the Sikorsky S 92 to meet its needs stipulating that operators it contracts with such as CHC Helikopter Service will be required to use such equipment 32 Variants editS 92A edit nbsp S 92A at Wagga Wagga Airport in 2015 The S 92A is the civilian variant and is available in a number of versions The civil transport version has an airliner type interior that seats 19 passengers The utility transport version has 22 side facing seats with a full cabin width rear ramp The 733 sq ft 68 1 m2 interior cabin area can also be configured to accommodate up to three airline style LD3 cargo containers Additional stowage space is available in the 140 sq ft 13 m2 area located in the aft ramp compartment During development it was referred to as the S 92C Helibus H 92 Superhawk edit The H 92 Superhawk is the military variant of the S 92 It has been demonstrated to the U S Air Force Marine Corps and Coast Guard The H 92 has more powerful GE CT7 8C engines rated at 3 070 shp 2 290 kW and unlike the S 92 has fly by wire flight controls The search and rescue variant provides space for seats litters auxiliary fuel cell and SAR emergency equipment In July 2004 the H 92 Superhawk was selected by Canada for its Maritime Helicopter Programme MHP as the CH 148 Cyclone Canada ordered 28 helicopters in November 2004 33 The program has been delayed multiple times 34 As of November 2019 nineteen CH 148 Cyclones have been built delivered and accepted by the government of Canada The Canadian military declared initial operational capacity in June 2018 and expects full operational capacity by 2022 35 VH 92 edit Main article Sikorsky VH 92 The S 92A variant designated VH 92 will be used as the next Marine One to fly the U S President 36

due to fractured oil pump studs and was forced to make an emergency landing 70 This incident led to Sikorsky issuing a notice to replace titanium gearbox studs with steel studs This refit had not yet been conducted on the Cougar Helicopters S 92 that crashed the following year citation needed On July 19 2008 an S 92 carrying Rev Sun Myung Moon crashed in South Korea 71 The helicopter was flying in inclement weather that forced it down on a hillside The 16 people aboard were slightly injured in the crash 72 73 On March 12 2009 Cougar Helicopters Flight 91 an S 92A operated by Cougar Helicopters carrying 18 passengers and crew en route to oil platforms off the coast of Newfoundland crashed and sank in 170 meters 560 ft of water 74 during an attempted ditching One person was rescued from the North Atlantic with serious injuries 75 and the others did not survive 76 The crash was determined 77 to be caused by 16 separate factors The primary cause was galling or fracture of titanium gearbox studs that had not yet been replaced with steel 78 On December 28 2016 a S 92 registration G WNSR serial number 920250 79 operated by CHC Helicopter experienced unexpected control responses whilst in mid air on a routine shuttle flight between two oil installations in the North Sea The pilots conducted an emergency landing on the West Franklin platform 80 The helicopter is reported to have spun on the helideck during the landing damaging the helicopter wheels and rotor blades 81 The helideck also sustained damage during the emergency landing 81 There were no reported injuries amongst the nine passengers and two crew during the incident 80 The aircraft was transported back to Aberdeen via ship at which time the Air Accidents Investigation Branch began their investigation into the incident 82 Sikorsky issued a notice on January 9 2017 grounding all S 92 aircraft until the tail rotors have been inspected The inspection work takes approximately 11 man hours to complete 83 The Air Accidents Investigation Branch issued an update on January 11 2017 that reported that the tail rotor pitch change shaft bearing had seized The bearing showed signs of severe overheating and significant wear The failure of the bearing allowed the tail rotor driveshaft to damage the tail rotor servo The damage to the tail rotor servo is considered to be the cause of the loss of tail rotor control The health and usage monitoring systems had discovered the flaw the day before flight but the maintenance crew had not 84 On March 14 2017 a S 92 operated by CHC Helicopter under contract to the Irish Coast Guard crashed off the west coast of Ireland with four crew members on board Three of the crew were initially missing Captain Dara Fitzpatrick was recovered from the water but later died in hospital 85 The helicopter crashed into an unmapped island in poor weather The helicopter fuselage was located 86 Captain Mark Duffy s body was recovered in the helicopter s cockpit on March
