Looks to me Sikorsky never did an oil out test, just closed off the oil cooler and ran with hot oil and ignored loss of oil from elsewhere, inspiring unwarrented confidence.
Shell Management, I do not see how a few statements about how well the "test" went with the Oil Cooler Bypass activated can lead to a conclusion that they never did an oil out test.
Sikorsky stated that they did do such a test and that it failed, hence the bolt on Bypass Valve (drop me a PM if you need a reference). The valve was never part of the plan, full compliance was and as has been stated elsewhere the Blackhawk gearbox demonstrates that it is possible.
SASless, I don't know if the original oil out test was observed by the FAA, but I would have thought it would be. If I were a manufacturer I wouldn't want to write-off a MGB just to try it out, then have to do it all over again with an inspector present
