CHC operates two AS332Ls out of Halifax, neither an L1 nor L2.
Thanks Bladestrike, couldn't get anything off the CHC website to confirm the current model used in YHZ.
Last known incident that I can see with this model was G-TIGF in Dutch sector back in January 2005, lightning strike that did some damage but didn't stop the flight.
IMHO BP's stance with Bond makes sense, nothing conclusive announced as yet on this tragic event, better to err on the side of caution. I flew most of my North Sea days to BP installations, and I must say they practice what they preach wrt. safety. Here's to hopefully a quick answer from the AAIB.
