Helitrans (Norway) AS-350 missing off coast of Germany

I had an overspeed followed by engine quiting in a SD2 couple years ago. Turns out it was a bearing in the governor let go, but first indications due the engine overspeed were of a tail rotor driveshaft failure....made for interesting times on the way down. Successful Mayday and landing and p/u an hour later due a good floatplane buddy. Oh yeah upon flare and landing, took the driveshaft out so yep lucky.....but we were thinking tail rotor driveshaft Until bench test on engine a la Honeywell confirmed failure was due Governor bearing failure, first indication was a huge yaw before N1 et al started winding down. Was my third engine failure in over 12000 hrs but didn't even get an indication before it all went pair shaped .....beer and smokes went down really well on recovery to camp......ha ha
