The TSB wrote a very detailed Report...and conducted a wide ranging investigation and documented their work.
They addressed the Run Dry issue, and clearly described the situation that existed at the time of the Accident.
The had access to the CVR and know the content and context of the discussion between the Cougar Base and the Crew....but do not go into detail what that was.
They plainly reported their findings which included the conversation held between the Captain and the The Base so we have to accept the TSB would have reported any mention of a 30 Minute Run Dry Time. They did not....therefore it follows there was none.
The CVR also had no mention of that.
The RFM had no mention of that.
The Cougar SOP had no mention of that.
The Checklist had no mention of that.
The TSB discussed the multi-year long argument here at Rotor Heads, without naming the site, and concluded the 30 Minute Run Dry situation had reached a point that no reasonable assumption could be made that it was valid.
Sikorsky and the Operators of the 92 held weekly Web Casts discussing 92 issues amongst which was the MGB and all the issues surrounding that.
Folks who cling to the Myth this accident occurred because the Crew thought they could fly for 30 minutes with a Dry MGB are just not accepting the facts.
The TSB very clearly challenged the FAA and other Authorities over the Certification process and the Run Dry issue, as well as Sikorsky. They did a very good job at discussing the entire issue of Run Dry Gearboxes.....and did not just limit themselves to the Cougar 92.
Strongly held False Ideas, no matter how firmly believed....are still wrong. FH is welcome to his opinion but he is not entitled to his own set of facts. I take mine from the TSB Report.....all of it.
