Lone,
I have flown Bell 212's that had well over 35,000 hours....if I remember correctly we had one go 41,000 hours....before being sold off as scrap only to find new life in Canada after a proper overhaul/rebuild.
I have a Clock from one that I flew on its last Revenue flight and it had 37,000 hours.
The Columbia Helicopters 107's are probably far over those hours and keep on flogging about the World.
