The Sikorsky S-76 Spirit is a twin-engine medium utility helicopter that can accommodate a basic crew of two and
up to 13 passengers. The Sikorsky S-76 helicopter is mainly used for cargo and passenger transport to oil platforms,
in V.I.P. version and emergency. In 1975, Sikorsky Aircraft Corporation started the development of the Sikorsky
S-74 medium lift helicopter for the offshore/ oil support sector. The S-74 was subsequently redesignated the S-76 in
honor of the U.S. Bicentennial. Sikorsky's design work on the military S-70 helicopter (selected for use by the United
States Army as the UH-60 Black Hawk) was utilized in the development of the S-76, incorporating S-70 design technology
in its rotor blades and rotor heads. The first prototype S-76A, powered by two Allison 250C30S turbo shafts, flew on
13 March 1977. The FAA certification (TCDS H1NE) was achieved on 21 November 1979 and deliveries started the same year.
284 Sikorsky S-76A helicopters were manufactured, a large number were modified to S-76A+. The Sikorsky S-76B
with the Pratt & Whitney Canada PT6B engines was flown first on 22 June 1984. Deliveries started in 1987 and the
final S-76B was delivered in December 1997, with 101 S-76Bs built. In June 1989, the Model S-76C, fitted with Turboméca
Arriel 1S1 engines, was announced. The Sikorsky S-76C flew first on 18 May 1990 and FAA certification was achieved on 15
March 1991. The Sikorsky S-76C++ helicopter was the version in production until 2011. Its main feature is the Arriel
engine, which gives excellent single-engine performance as well as good range. In 2011, with aircraft number 882, the
last S-76C++ closed out that production progam. The last development of the Sikorsky S-76 helicopter was the S-76D.
The S-76D helicopter featured all-composite main rotor blades, Pratt & Whitney PW210S engines and Thales TopDeck
avionics. FAA approved Type Certification for the S-76D helicopter on 12 October 2012. Sikorsky delivered the first
S-76D aircraft to Bristow Group, Inc. for offshore oil worker transport in December 2013. Until 2020, Keystone / Sikorsky
built over 1000 S-76 helicopters in various models. The Sikorsky S-76D helicopter was the last version built. Sikorsky took
the decision to end domestic production of the S-76 following an FAA mandate that all new-production helicopters be equipped
with crash-resistant fuel systems. The ICAO Aircraft Type Designator for the S-76A helicopters is S76.
On 6 November 2015, Lockheed Martin completed for $9 billion the acquisition of Sikorsky Aircraft,
replacing United Technologies as Sikorsky Aircraft’s parent company.
In September 1981, the 1980-built Sikorsky S-76A s/n 760093 was registered D-HOSA in Germany with Wiking Helikopter Service GmbH, Wilhelmshaven.
On 15 September 1993, the helicopter was registered G-BVCW in the UK as chartered by Brintel Helicopters t/a British International Helicopters.
On 23 December 1994, registration G-BVCW was cancelled as exported to Germany and the helicopter
was restored as D-HOSA in service with Wiking. Sikorsky S-76A D-HOSA is christened "Skua". In the period September 1997 - December 2003,
the helicopter was operated in an EMS role as 'Spirit of Saint Luc' at Centre de secours médicalisé de Bra-sur-Lienne (ASBL) in Belgium. In 2016,
Sikorsky S-76A (modified) D-HOSA was withdrwan from use and on 15 September 2016, registration D-HOSA was cancelled. On 18 November 2016, the helicopter
was registered in Switzerland as Sikorsky S-76A++ HB-ZPP with BF Commodities SA, Barbengo. On 28 February 2017, the HB-ZPP was transferred to Aviapro,
and on 19 October 2017 to Eli Lake. On 3 November 2017, registration HB-ZPP was cancelled as exported to South Korea and registered HL9641 with Sejin
Aviaition. On 30 July 2008, Wiking Helicopter Service' Sikorsky S-76A
D-HOSA "Skua" was seen at the Wiking location in Sande at the grounds of Flugplatz Wilhelshaven-Mariensiel (EDWI) also known as JadeWeserAIRPORT.
