Helicopter Sikorsky S-76B Serial 76-0355 Register C-FIRW N7689S used by Coulson Aircrane Sikorsky Helicopters. Aircrane Ltd. is a privately owned family company based in Port Alberni, British Columbia, Canada. The company has over 110,000 safe flight hours and has been in the aviation business for over 29 years; operating a diverse fleet of both fixed wing and rotary wing aircraft. Sikorsky S-76 is an American medium-size commercial utility helicopter, manufactured by the Sikorsky Aircraft Corporation. The S-76 features twin turboshaft engines, four-bladed main and tail rotors and retractable landing S-76 is of conventional configuration, with a four-bladed fully articulated main rotor and a four-bladed anti-torque rotor on the port side of the tailboom. Two turboshaft engines are located above the passenger cabin. In the prototypes and initial production aircraft, these engines were Allison 250-C30s, a new version of the popular Allison 250 engine developed specially for the S-76, with a single-stage centrifugal compressor instead of the multi-stage axial/centrifugal compressor of earlier models of the engine, rated at 650 shp (480 kW) for takeoff. These engines are connected to the main rotor by the main gearbox, a three-stage unit with a bull gear as its final stage rather than the planetary gear used by previous generations of Sikorsky helicopters. This arrangement has 30% fewer parts and lower costs than a more conventional design. The S76B is Powered by two Pratt & Whitney Canada PT6B-36A or Pratt & Whitney Canada PT6B-36B turboshaft engines.
