Well that's all the negatives!
Plus side - loads of them going cheap. 502s have had their problems but plenty of spares and most problems now known so very few surprises. Roll back now no longer an issue anyway due to bleed take off modification that was moved a few stages down the compressor (mandatory now I beleive). Remove the aircon system then no dodgy fumes
Power might be flat rated but even in the USA the levels that this op will be flying at will hardly notice the degridation.
Also will give ex146 drivers someting to play with if they could be bothered in their spare time...maybe....perhaps...ok maybe not!
