Flying directly into a setting sun would almost certainly have been a contributing factor. I'm still troubled by the 40 second level segment, it's a long time. All the levers were in the full forward position when found in the wreckage, I'm not convinced yet that there wasn't a blade angle/negative torgue sensing issue. A fine pitch blade angle at max power would produce a Vmca somewhere in the order of 150 knots. Thoughts Horatio.
