Helidata Article at Heli-Tech about S-92 failures
Heli-Data put out a trade edition at Heli-Tech and discussed some of the important problems with the new Sikorsky S-92.
The article mentioned a uncommanded float inflation on approach to a rig, an engine failure during takeoff from a rig, a ground fire resulting from an electrical wire arcing against and burning through a hydraulic line, problems with vibrations and electronic dampers, Airspeed restrictions, Main gearbox lubrication pump problems and noise complaints from people on the ground.
I would not have liked to be in the Winged S suite about that time.
