If you read my post carefully 737 I think you will find it is accurate.
1. Aerodienst is not in the UK, I said that a UK company would have be approved OR maintenance would have to be done in Europe. This was in response to the 1st post which was written by a UK based author.
2. I said you MAY have engine noise problems
3. I also said IF you have to modify the aircraft for EGPWS, PRNAV etc. you may have a problem
Finally the lack of support was in the modification part of my reply. Bombardier will not be spending time or effort on mods for this aircraft, so work will have to be done by private companies. This adds to the complexity and cost of the work, as you don't have the backing of the manufacturer.
Without specific information on the actual aircraft, you can only give general advice. I standby everything written.
