Fundamentally it stated that in skipping the AFCS Check (since they were not going to fly) they also skipped the flight controls position check. This likely led them to advance throttles (flick the knob) to Flight on engines 2 and 3, the collective was at 45%, or 7 degrees of pitch, the cyclic was not centered and the machine lifted onto its side. Very generalized.
It also stated that the Check list states that due to elastomerics in the rotor head the collective will be partially up, and to NOT attempt to lower until there is hydraulic pressure.
