This must be one of those things that is being extencively overlooked I recon.
I, for not knowing about it, have picked up machines parked at airports around, or operated out of bases where the machines may have been parked for a few weeks between missions, and never ever heard about this.
What does the manuals for other engine-manufactures say on this point??
Nomad,
I think MightyGem was referring to a spare aircraft, not just an engine for the EC135T. Which will make things abit easier to sort out.
