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 910 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-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.
