Sorry guys, I've got to reign in your enthusiasm here. As previously stated the helideck is
fully compliant with the requirements of CAP437 and therefore ICAO Annex 14. The deck is also not "falling apart"!
Our operation has about five landings per flight hour so the concept of the design is well proven and not in question. This is the first such incident in many, many years of operation.
It's not appropriate for me to discuss here why the panel detached as the investigation is ongoing.
Now hopefully we can return back to my original question........
