@ SNS3Guppy
Thanks for your long detailed reply, it's helped alot. My point wasn't about the maintenance procedures themselves, though. They weren't performed because maintenance didn't know better then - no, they were performed in order to save time and costs (or so it seems from the report). Since your posting to me sounded as though the incident happened because of "outdated" maintenance performance ("In times past, where methods have been found inadequate...") and thus being unlikely to happen again; I'd just like to point out that my point was about saving costs and time, and THAT is not an issue of the past.
THAT was my worry - that poor / rushed maintenance might happen again because of financial and timely pressure. And of course, that it might be the plane I am on.
