The question to be asked is: "who chose the equipment for the helicopter?", then, "who designed the pilot training for that equipment?" then, "who approved the equipment and the training?"
You might go on to ask "who did the risk assessments", who designed the "change management" for the new equipment/procedures?"
When all has been analysed you may then point the finger at the operative - Joe Pilot.
Surely with this reasoning Geoffers, we could take the fault right back to the person that designed the helicopter?
The L2 has not had a previous CFIT accident so surely, the design, equipment and training must have been adequate for some time. It cannot suddenly become inadequate so I agree with TC's assessment in this case.
