This seems to be the same item that was the subject of an AD on 30 August. Can't see any diference in either problem or temporary or permanent fix.

(Edited to add)

Now there's been a second AD issued the following day which does indeed add something new. B747-400 operators have now been restricted from using the fuel tanks in the tailplane, which for Qantas at least gives issues for LAX-SYD and SIN-LHR. It's not only that the aircraft would have to make a fuel stop (LAX-SYD would stop in Auckland), but as crew flight times are close to the limit having to make a stop could put them over, meaning crew changes at the intermedate point, so could indeed be some disorganisation.
