If it is anything like having the 341 on the YU reg it is to do with cheaper parts.
I used to fly 2 x 341's for owners, one on the G plate ( EASA machine )and one on the Yu plate ( both civil ones not ex mil). the clutches had gone in both machines. Eurocopter charged £ 37 k for the G plate one. The Yu clutch came straight from the factory in Bosnia ( not an EASA signatory ) and was £ 7500. On later investigation ( paperwork left in box ) the G plate clutch had been been purchased by Eurocopter from the factory in Bosnia, they then charged £29000 for putting an EASA Form 1 on the clutch, nice work if you can get it !!!!!
