Wow!
Good find and thanks!!
I'm glad I'm not an owner or a tool spinner..
Looking at the dates, I'm hopeful the ships that I steer are not effected.
Find out tomorrow I suppose.
Cheers!

One of our R44s had these bearings fail on a recently overhauled engine late last year, the engine did under 200 hrs after overhaul and one day a change in noise from the norm at idle was the first and only sign we got, and plenty of metal in the filter. :shock:
