I've have read everything since the day it happened and I'm as shocked today as I was when I first noted that the S92 did not have to have a 30 min. loss of lube test prior to certification.
It's been my experience that the "extremely remote" alternate means of compliance is to be based on extensive in service histroy of a similar type. The S92 was a brand new type certified Cat A to FAR part 29!
Those guys should have had a better chance, it's not just 30 minutes run dry, but 30 minutes at a cruise power to be specified and approved by FAA prior to the test.
I've held my comments until know and only chipping in because of the column in Helicopters magazine today, which seem to point directly at the crew. "If the pilots had initiated an immediate.... everyone could have lived."
