Torcher,
Not trying to be picky here but in the RFM definitions....what is "May" defined as meaning? Generally it is permissive in application.
In real language it means something really different such as meaning "may yes....may not!
I guess the Sixty Four Dollar question that Sikorsky and the FAA are going to have to answer is "Did they run a MGB with a complete loss of lubricant in the presence of the FAA?"
