What a load of crap Sunfish!
Playing the Devil's advocate here - QANTAS is trying to compete with the likes of V Australia, whose maintenance base is in LAX, with SIAECUSA - look them up...
In actual fact, QANTAS could potentially have their B744's and A380's main Line Maintenance base in LAX tomorrow, if they choosed to use SIAECUSA, as that company is already an FAA approved repair station for those types. Remember guys, as far as CASA is concerned, VH registered aircraft can be maintained by any approved Contracting State. Doesn't have to be in Australia.
