"Quote:
The Board concluded that at the time of the accident crew duty time limitations had not been exceeded and that fatigue was unlikely to have played a part in the accident"
This was, after all, an operational environment.
The 14 hour crew duty times limits laid down are not absolute. In other words, going beyond them does not guarantee an accident nor should it be be deemed negligence. I speak from personal operational experience, not from some shiny-arsed, idealistic, fixed wing, never flown SH, never been in theatre viewpoint.
