Anyone remember the Queensland accident many moons ago, involving a B222 and a Long Ranger
The poor old 222 pilot was quietly having a coffee some distance away from the helipad, when the LongRanger landed and hit the 222 blade, with at least (IIRC) one fatal amongst the LongRanger pax.
It cost the 222 pilot >$40k in legal fees when he was charged (with manslaughter, I think) before the Queensland police withdrew the charges. I believe the pad was regularly used for 2-3 helicopters as a normal operation, on the basis that the blades were secured fore and aft on the machines that had shut down. The 222 pilot was well and truly hung out to dry on the accident
