Rif raff, Sikorsky uses 4 points of attachment for their "stressed" gearbox. Also, the S92 is on phase 3 of it main gearbox. There have been failures (cracks found) of mounting feet and in fact are still quite closely monitored by HUMS. Not much point in have 2 bolts when the entire foot is detached from the gearbox. Seems they have finally nailed it now though and luckily there were no accidents in the process, no more cracked feet, however, I believe there have been a couple frame issues since.
Every manufacture out there could make a helicopter that would never fail, problem is it would never get off the ground. Hey why not throw an extra motor in, then we would never have to worry about single engine performance either.
