Well as a DPE I can assure you that anyone coming to me for a check ride will have to demonstrate a touchdown. All the other DPE's I have spoken with are of the same opinion.
The only people in the helicopter industry that aren't current on the maneuver are the FAA themselves. Due to a serious lack of funds they hardly get to fly. As of a couple of weeks ago there were 38 current helicopter guys in the FAA. For the entire nation.
My local FSDO has two helicopter pilots that haven't flown in nearly two years. The problem lies within the FAA itself and is certainly not meant to cover a DPE's lack of currency or skill.
