I'd like to understand what the NTSB had in mind when this text was added as a recommendations:
In the section titled RECOMMENDATION (How could this accident have been prevented) of the operator's written report (NTSB Pilot/Operator Report, Form 6120.1), the operator stated that the flight deck on Platform Irene had recently been repainted. The "H" symbol was offset from the previous position, and the reference line had not been repainted. He reported that pilots used the reference line, or "Butt Line," to determine where the pilot seat would have to be located to allow adequate tail rotor clearance when "swinging" the tail around. The operator recommended that the "H" symbol be repositioned, and the reference line be repainted. He also thought that a profile view depiction of the flight deck and surrounding obstacles could be published to help pilots determine possible problems with particular approach paths. Lastly, he recommended that all company pilots be briefed on these changes and the associated hazards and methods to avoid similar accidents in the future.
Remember that this was a less than 1D deck; (probably) with obstacles closer than permitted in Annex 14 (CAP 437). Is it likely that such a recommendation was written by someone without sufficient knowledge to make such statements?
