Paragraph (a) bears repeating: (a) In the event of an engine failure caused by a major mechanical fault (e.g. seizing bearings due to loss of oil), the rate of deceleration of the engine can be rapid and it is thus imperative that the pilot take immediate action to feather the propeller before the rpm falls to the 1000 rpm region.
To be quite blunt, I don't see the evidence of this failure mode being a major problem.
Human factors issues though... I can readily accept a need for improvement.
Training for good, quick, emergency response to a critical EF is difficult. I had a good ME instructor who once (near end of training) gave me an unbriefed EF during a radio call. I fixated very nicely on the radio call and learned a good lesson from the result.
Not sure how to fix that problem though, except the same way it was fixed with me. Better instruction.
