Boeing airworthiness directive

This made the CNN website:

FAA issues new Boeing fuel pumps order

Quote:

<font face="Verdana, Arial, Helvetica, sans-serif" size="2">The order, issued Saturday but taking affect Wednesday, requires airlines flying Boeing 747s, 757s and next-generation 737s to keep enough fuel in the center fuel tank to keep the suspect fuel pumps submerged.</font>

There is also a directly related thread in the CX forum.

I imagine this means more variability for loading and interim refueling stops on the longer longhaul flights.

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.
