The S-76 helicopter has been in continuous production for more than 38 years, but at least once a decade Sikorsky engineers have updated the helicopter with a newer engine and/or avionics to keep it competitive. Over its lifetime, the S-76 has been powered by various engine families to enhance performance, range and reliability. The S-76D delivers a whole lot more performance, less noise and a better cockpit than the corporate S-76C+ that is popular in the Ontario market. Its new engine and rotor system performs better overall, including with higher payloads under Cat A operating conditions. A platform with more than seven million trusted and supported flight hours, the S-76 answers the call for these varied mission segments.
