The Globe and Mail: Sikorsky objects to claims helicopter failed to achieve certification
In particular:
'Although the investigation is ongoing, investigators have zeroed in on a problem that forced a S-92 to make an emergency landing in 2008: the studs that hold down the gearbox oil-filter assembly were broken, which would allow the oil to drain out.'
Are they referring to the Shell S-92 that made a forced landing in the Brunei jungle? Think it was a similar problem.
