If that were the case the type should be grounded. The fact that FAA have not and Shell only briefly downgraded the type to 'non-prefferred' over the MRGB churning issues, shows there is no problem.
IMO the S-92 should have been grounded after Broome, which would appear to have been totally covered up as the independent team in Vancouver highlighted enough issues with the titanium studs to justify complete grounding of the fleet until the studs had been changed out to steel.
There is a problem, we still do not have a robust solution applied in service for the S-92 MRGB to give us 30-minute run-dry time and no more mounting feet cracks.
IMO FAA and SAC are smoke-screening Joe public in the hope that it will "all go away". I don't think so. Cougar suing SAC and the TSB report still to be published will hopefully make sure of that.
What finally happened with the CH-148 MRGB, did it get 30-minute dry run time or are they going with the extremely remote statement?
Safe flying
