When I worked with aircraft maintenance airlines very rarely bought their aircraft, they leased them through many types of lease packages. I do not think that things have changed that much today what with aircraft costing upwards of $100m each. One of the major rules within any lease was that the owner (the plane manufacturer) stipulated where the plane was serviced, and that was always with one of its licensed service centres with licensed engineers and up-to-date servicing equipment/systems. For in-op snags it had to be signed off to local or home standards, whichever was higher.
It is a bit like buying a a car and having to have it serviced with a dealership in order to maintain the guarantee, only when it is outside of guarantee is it OK to go to any garage.
The DC-9-MD83 (type) that just crashed was last delivered in 1999 making it, at least, 15 years old - though we do not know that age of the actual plane. The '83 major production years were from 1987 - 94. That is not to say that Swiftair were not having it serviced to the highest standards. As a European operator they probably were, given that the crew was Spanish, but it might have been nearing is end-of-life and in need of a lot of TLC.
My take on flying is that it is one of the safest ways to go, but I still prefer airlines that I know over ones I have never heard of.
