Can the maintenance records be traced? That is, can a look at a reconverted aircraft's tech log, and be reasonably certain the the various necessary work has been done at the right times through it's life (inasmuch as one can ever do this from the tech log)?
For my own curiosity, what was the reasoning behind so many of these aircraft being registered in Hungary instead of the UK? Just the usual wish to avoid the high prices and massed beauracracy of the CAA? Or something more?
