i'm back in England now, left the helicopter in Holland. Was not intending to fly it until fully checked an given go ahead from engineer.
What I found on the detector was some shiny and dark grey thin pieces all the way around the detector the detector is obviously magnetic (may sound stupid to some of you but i'm not experienced with these things) and the particles were about 2mm in length all the way around the detector.
if it means anything the tail rotor gb was overhauled about 10-15hrs ago....
An engineer whom I know as he worked on our aircraft came down, inspected what he saw and we ran the engine on the ground for about 10mins, no light came on but more particles were found.
Doesn't sound good to me so I won't fly it.
How much of a big deal is the replacement of the tail rotor gbox?
