I think the engine A/D is just overdue on the 522 engines.
But its was supposed to be accomplished by AUG 2006.
No alternate method of compliance has been done to many of these 522 engines, not sure if they even have one that was done correctly according to RR and the manufacturer.
-500's flying with the RR 524 are ok.
Maybe some ground engineering types can provide some good updated info.
I seen this Privelage Jet Tristar last year in JED,I think it was a -500, but memory declines with the age I guess.
