Sikorsky is to deliver three S-76C++ helicopters to Líder Taxi Aéreo Air Brasil under a new contract.

The S-76C++ helicopter features new Turbomeca Arriel 2S2 engines, an inlet barrier filter to protect the engine against erosion and environmental contaminants, a new health and usage monitoring system and a gearbox with quiet zone technology to reduce interior noise levels.

The helicopter engines provide about 350lb additional payload capacity at high altitude compared with an S-76C+ helicopter.

Líder will operate the aircraft in Brazil for offshore oil operations.
