I was thinking more along the lines of Sikorsky's SSA-S92-08-006 referred to in post #1305. I haven't seen the circular but I wonder if it contained poor advice that might have been a factor. Anyone know what it said?
The circular was simply referring to a possible change in the RFM procedures. It is odd that the regulators have taken such a visible objection to it's content as it didn't actually state anything of substance. It was basically saying " please keep an eye out for an RFM change".
The changes that it was referring to would also not have made any difference to the outcome of this accident IMHO. The drill for an indicated MGB oil px of below 5 psi would still have been LAND IMMEDIATELY.
