I think the ownership structure is rather opaque, as alluded to by this:

Certain jobs at the hangar are advertised on the Ryanair website but applicants were invited to reply to a Prestwick Aircraft Maintenance Limited email address (
[email protected]). (see here:
http://apps.scottish-enterprise.com/...splayID=104925).
PAML seems to be a company registered in Scotland (see this:
http://www.gazettes-online.co.uk/dow...p?docId=991196) which suggests it's not wholly-owned by Ryanair.
However, Ryanair's filings with the SEC in the US (see this:
http://www.secinfo.com/$/SEC/Filing....4Bmp.21az_3q0f) mention a hangar at PIK leased for the purposes of aircraft maintenance.
I suspect that FR have some degree of ownership of PAML but have an agreement with Scottish Enterprise to get generous training grants.
