Standard overhaul you are quite right, it does seem a little tense - this thread.
Please ask away and those who know will surely help?
Dead Man's Curve:
Twin's do have a very small DMC but it is very very small. Take-offs and landings stay out of them. Cruise obviously stays out of it.
Police helo's hover a LOT and "x" % of the time they are well clear of the DMC. Occasionally in the heat of a chase etc they can inadvertently drift into the zone but it is rare.
In this particular case - indications (eye witness/pictures/noises) suggest the main and tail rotor blades were stationary or close to that. For that to be the case as a consequence of being in the DMC it would suggest he lost both engines and didn't lower the collective at all prior to hitting the deck.
