Good advice from Blues.
If you do contact Manchester for advice, you will end up talking to me anyway! So here is what I'm going to say:-
No. - The L24 is not the aircraft for Europe.
Here are some reasons why
RVSM is a problem. Very few (if any) L24 aircraft have been modified to fly in RVSM airspace. Bombardier do not have an approved modification for the conversion, the work is being done by a private company in the USA. That means a height restriction which will cost you dearly in fuel.
You may well encounter a noise problem because of the engines fitted.
If you have to modify the aircraft for EGPWS and PRNAV etc. you will find difficulty as Bombardier are not really supporting the aircraft anymore, also interfacing with the older avionics fitted will be difficult.
I don't believe there are any approved organisations to maintain the aircraft. NEA do not have L24 on their JAR-145 approval. So maintenance will have to be 'invented' I.e a new company approved, or carried out in Europe. Either option will not be cheap.
There are more reasons, but the above should be enough!
As I said, good advice from Blue. Look towards a Citation 500. But make sure you get some GOOD engineering help in the purchase stage. A good aircraft doing well in the USA, may not be all that is required to operate successfully in the UK. Think about the points above, other than the engine noise they apply equally to the Cessna range.
