It is worth trying to read the full ATSB report on this incident rather than only the summary. Seems lots of elements came into it. Pilots touchdown positioning may have been influenced by marked manholes in the landing zone. I am also left wondering if the stanchions on the side the helicopter approached had accidentally been left in place by the crew on this occassion (despite a request from the marine pilot) given the stanchions on other side had been removed for that landing? Or were stanchions regularly left in place on previous occassions? As for positioning of tail rotor, seems access to the deck hatch could be from either port or starboard side so with a transverse approach the tail rotor would invariably be over either one or the other access steps. Marine pilots would be trained to approach the helicopter from the front. I wonder how many helicopter pilots had been lucky with landing on this ship prior to this incident?
