About the Sikorsky S-76

The Sikorsky S-76 is a twin-turbine medium helicopter that has defined the corporate and offshore transport market since its introduction in 1979. Originally designed to serve the booming oil-and-gas industry, the S-76 became the gold standard for executive transport, combining jet-smooth turbine power with a spacious 12-passenger cabin and all-weather IFR capability. Its twin Turbomeca Arriel or Pratt & Whitney Canada engines provide exceptional safety margins over water and in demanding environments, while the four-blade main rotor delivers a cruise speed around 145 knots and a range exceeding 400 nautical miles.

The S-76 family has evolved through multiple variants, from the original S-76A through the C, C+, C++, and the latest S-76D with advanced Pratt & Whitney PW210S engines and an all-composite main rotor blade system. It serves diverse roles: offshore crew transport to oil rigs, air ambulance missions, corporate shuttle, and even heads-of-state transport. The type's reputation for reliability and smooth ride quality made it a favorite among VIP operators worldwide, though its operating costs keep it in the premium segment of the rotorcraft market.

With a never-exceed speed of 155 knots and a maximum takeoff weight of 11,700 pounds, the S-76 occupies the sweet spot between light twins and heavy-iron helicopters like the S-92. Its retractable landing gear and sleek fuselage give it a distinctive profile on any helipad. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
