Bond Sikorsky S-92A North sea worker's transport between Aberdeen and oil Platforms.
The S-92 is multi-purpose helicopter powered by twin GE CT7-8A turboshaft engines and has an aluminum airframe and some composite components. The four-bladed fully articulated composite main rotor blade is wider and has a longer radius than the Sikorsky S-70. The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Most of the rotor system components aside from the blades are titanium.[citation needed] The S-92 features an active vibration control system, using vibration sensors and structurally mounted force generators to increase flight comfort and lower acoustic levels to below certification 2008 study by Norway's Flymedisinsk Institute found that the S-92's vibration levels were 42 percent above that of the Eurocopter EC225 Super Puma; Sikorsky disputed this finding, saying that the study hadn't used their latest anti-vibration technology. In February 2011, the noise and vibration levels were reportedly subject to health concerns, allegedly causing tinnitus and heart problems. A number of safety features such as flaw tolerance, bird strike capability, and engine burst containment have been incorporated into the design. Adherence to FAA FAR part 29 has led the FAA certification board to call the S-92 the "safest helicopter in the world". The S-92 reportedly met the FAR part 29 "run dry" requirement by asserting the loss of oil pressure in the main gear box is "extremely remoteThe S-92A is the civilian variant and is available in a number of versions. The civil transport version has an airliner-type interior which seats 19 passengers. The utility transport version has 22 side-facing seats with a full cabin width rear ramp. The 733 sq ft ( m2) interior cabin area can also be configured to accommodate up to three airline-style LD3 cargo containers. Additional stowage space is available in the 140 sq ft (13 m2) area located in the aft ramp compartment. During development it was referred to as the S-92C Helibus.
