Qantas A380 mer skadet enn først antatt

Fra Down Under kommer denne meldingen:
QANTAS A380 WAS HEAVILY DAMAGED


The Qantas crew whose A380 suffered an uncontained engine failure earlier this month had their hands full in getting the super jumbo back to Singapore. Shrapnel from the engine disabled one of two main hydraulic systems, hampered the fuel transfer system, punched a hole in the forward wing spar and caused a major fuel leak. The cascading nature of such failures meant the pilots couldn't dump enough fuel to bring the aircraft down to its maximum landing weight and the fuel left in the airplane was unbalanced. Flaps, slats and spoilers couldn't be fully deployed and the gear had to be dropped manually. Once it was on the ground, the anti-lock brakes didn't work and, since the damaged engine was an inboard one, there was only one left for reverse thrust (the outboard engines of A380s don't have reversers because they often overhang the grass and might be FOD damaged). The heavy, significantly disabled aircraft needed virtually all of the 13,123 feet of available runway. Meanwhile, the cause of the engine problem has been determined and it's just adding to the PR problems facing manufacturer Rolls-Royce.
 
I tillegg så fikk en ikke stoppet motor nr. 1, den ved siden av den skadde motoren. Det betød at FDR/CVR fikk strøm som førte til at utstyret tuslet og gikk og slettet viktige data etterhvert som tiden gikk.
