Mad, sorry, but you cannot defend the tris replacement program at GR. Everyone knew at least five to six years ago that the tris would never meet EASA requirements, without massive amounts of work and probably more importantly, constructor help and support. It's been mismanaged for way too long.
Sure, Mr Darby has done his best since he arrived but the previous management stuck their heads in the sand. BI got rid of theirs in 2011 and publicly stated that the main reason was that they were never going to be compliant with the new Europe wide requirements. Utter madness not to have sorted this years ago.
