European Aviation Safety Authority (EASA)
The Europe wide equivalent of the US FAA. An organization replacing JAA, but unlike JAA this one has the power to regulate rather than advise national authorities. It's intended purpose is to produce common European Standards in Aviation. So far it has just produced more red tape and increased costs for aircraft owners.
Civil Aviation Authority (CAA)
The CAA is a company tasked by government with the regulation of UK aircraft and airspace. Now subservient to EASA and EU law, it will slowly be assimilated into EASA.
G-INFO - The online UK aircraft register from CAA. Returns information on the aircraft, owners even their address. Burglars and junk mailers love it!
Light Aircraft Association Ltd (LAA)
An association, now a company delegated by the CAA with responsibility for amateur built and some vintage aircraft in the UK. Unlike the USA's EAA it has a legal responsibility for the safe construction and operation of such aircraft. It tries to be both a regulator of permit aircraft and representative for their owners; conflicting roles that it carries out with some success.
