SUEA's the one that got piled in at Land's End, using wet grass in rather unfavourable conditions... AAIB report is available to stop me commenting further!
AFAIK FCAB did the full 1050 hours until the existing Thielerts were grounded, so not an insignificant amount of hours to fly in well under 3 years CPL/IR training.
RE Thielert PA28s: I did my FI rating on them, and do a fair amount of work with some at the moment. They are rather fragile, good maintenance is absolutely vital, as is a good installation. As training tools they are actually quite good for teaching the basics on - I've no doubt that FADEC and SLPC is the way that PPL training will go in the future. Just annoying that basic faults get repeated so often in the design process!
Does sound like Diamond are doing a good deal for FCAB's owners - far better than Thielert would ever have done, so maybe salvaging something from the wreckage? They certainly can't afford to have a disaster with the Austro Engines, that'll close them down permanently!
