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 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 with the development of the Sikorsky S76 medium lift helicopter for the offshore/ oil support sector, based on the military S70 Black Hawk program. The first prototype S-76A, powered by two Allison 250C30S turbo shafts, flew on 13 March 1977. Deliveries of the production model started in 1979 after FAA certification was awarded in November 1978. 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 in April 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 latest development of the Sikorsky S-76 helicopter is the S-76D. The S-76D helicopter features 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 2014, Keystone / Sikorsky built over 900 S-76 helicopters in various models. The Sikorsky S-76D helicopter is the version currently in production. The ICAO Aircraft Type Designator for the S-76B 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.

On 20 February 1992, the Sikorsky S-76B s/n 760395 was registered N1WL in the USA with Warner Lambert Company, Morris Plains, NE. Since, the 1992-built Sikorsky S-76B was re-registered N1HE; N5QZ and N908GM in the USA with different owners / operators. On 27 September 2010, the S-76B was registered as N53RD with Aircraft Guaranty Corp. Trustee, Onalaska, Texas. In 2010, registration D-HHNH was reserved for the S-76B. On 14 January 2011, registration N53RD was cancelled as exported to Germany. On 16 February 2011, the Sikorsky S-76B was registered D-HHNH in Germany with HeliService international GmbH, Bremerhafen, as operator and Helikopter Vermietungs- und Verpachtungs GmbH, Bremerhafen, as owner. The helicopter is operated by HeliService international out of Emden airfield to transport people and equipment from/to the offshore windfarms. On 19 March 2019, registration D-HHNH was cancelled as exported to Serbia, where the helicopter was registered YU-HOH.
