The Emergency AD was issued after Bell submitted an ASB after our TGB was found to be loose. They were investigating another 1/2 units found to have issues and were apparently just about to issue an ASB when ours was found by pure chance.
The Wiltshire problem seems to be unrelated to the AD issued regarding loose TGB's.
We are awaiting a resolution at the moment but there is more work required than just replacing the Gear Box im afraid. We have been offline nearly a month so far, but are hoping to be back in the air within the next 10 days or so.
