That I noticed as well, but then soundtracks can be faulty ..
Who knows, maybe it was faulty, it is a C-model, so a bit overstressed engine compared to other H269 and Robby's ..
Who knows, in a H269 not having a governor installed, it could be he was paying more attention to his low height over the treetops, maybe without having safespots in sight and got caught in a minor low-RPM situation, not that uncoming in a H269 - if so, now probably descending slowly and instinctly not wanting to descend into the trees, he didn't lower collective a bit to "catch the RPM" again, because he had no room for that, making things worse, now still descending and with low rotor RPM, running out of power and lift - that's my guess on the assumption that I hear a fairly lower engine RPM yet seemly smooth running engine, when it start to settle into the trees even before chopping them up to pieces, but who knows - only NTSB will know when time comes ..
