Try speaking to Kingston Uni regarding courses. They are advertising and Aeronautical Engineering degree which you might be able to get into post-grad.
If you're a IEng or the like you probably know the publications to check out for jobs but look in the Telegraph on Thursdays and/or Sundays and Flight International weekly. As mentioned above, plenty of design jobs on the go just now - probably more design and development stuff than there is on the maintenance side.
Go along to the Royal Aeronautical Society, 4 Hamilton place, London as well. They might let you in to look at their library or at least have an "expert" there to chat about the subject/industry.
