SS - The irony of your post is staggering - the first accident in the AAIB report, you point to, is a double engine stoppage of a twin cause by fuel exhaustion - given that that may also be the case here (and other complete power loss events) it is tempting to conclude that the mathematical assumptions concerning the safety of TWIN ENGINED helicopters is FLAWED - is the rarety of full power loss in twins actually 10^-9 per hour ?
Anfi, Sorry, I didn't produce the AAIB Bulletin
Umm, if you care to read the first incident all the way to the end, you'll get to the bit that says, "no action was taken to select an alternative fuel source for the engines after their power loss."
Single or twin, if the crew don't switch tanks, the engine will stop
