Thank you for taking the time to answer that for me, Yes, I figured they must be amassing their hours on offshore platforms and the like as I dont see many apart from lighthouse support machines aorund overland.
I did speak to an angineer from Bond once who was involved on stretching them, and he was telling me a story about one of his bosses asking him to let them know when any in the fleet were nearing the 20000 hour mark as apparently Eurocopter wanted to have a look at their condition. Apparently his replied "tell them they're a bit late mate, three or four of them passed the 20000 hour milestone a few months back!
