Widge,
Horrible! The TRGB was returned having seized (on the bench, after removal) witnessed by Eurocopter engineers. After 2-3 months the bill for $US4,000 arrived, "no fault found", pay before we give you your box back. Some terse exchanges resulted in a more detailed inspection, and a repaired GB arrived back without much further explanation. Shortly after, an AD was issued recalling all TRGB's with the bearing that failed on my box
Fortunately the Kiwi's are looking like being able to do the overhauls in future
