Emirates A380 blows tyres on Lndg in VHHH

Apr-8-2012, 00:37 GMT

An Emirates Airlines Airbus A380-800, registration A6-EDQ performing flight EK-384 from Bangkok (Thailand) to Hong Kong (China), landed on Hong Kong's runway 07L at 17:33L (09:33Z) and vacated the runway via high speed turn off A7 stopping just past the hold short line with two blown right hand main tyres, the aircraft was disabled. The passengers disembarked onto the taxiway via mobile stairs about one hour after landing.

The northern runway 07L/25R was closed for about 4 hours until the aircraft was towed off the taxiway. The runway had been estimated to return to service by 23:30Z (07:30L Apr 8th Hong Kong Time), about 14 hours after landing.

Passengers reported they saw sparks from an engine at the right hand side and noticed a burning smell, the crew quickly announced they had burst tyres.

An observer on the ground reported maintenance staff were replacing a number of tyres.

Sources at Hong Kong Airport report the aircraft suffered an anti-skid failure on landing resulting in brakes blocking and causing two main wheels to be ground down to the axle.

The airline reported the aircraft blew two tyres on landing.

Seems like a long wait to disembark? I suppose there was no imminent danger, but don't pax get agitated sitting around waiting to be told what to do next?

could somebody rated on A380 throw some light.

"the aircraft suffered an anti-skid failure on landing resulting in brakes blocking and causing two main wheels to be ground down to the axle",

Could any A380 experienced crew suggest the reason for the same. The crew seems to have vacated the active runway and soon after stopped the airplane. Could they have been a better decision or is it expected to wear out to the axle for a tire deflation on landing.

Also why was the runway closed for operations for 13 + hours if the aircraft was disabled outside the runway.

I believe it caused a lot of delays due single runway ops to all departures and arrivals.

Two blown tyres, two wheels ground down to the axles; what were the other 14 doing?

Don't know if the systems have anything in common except the manufacturer but I've seen the ground down wheels on two A300-600's in years past allegedly due to interruption of electrical power to the antiskid control computer. One on a high speed RTO when the hot brake ECAM popped up with one set of brakes locked on, the other on the world's best short field landing, fully locked brakes on both sides. I surmise unstrapped economy pax were physically upgraded to first class in both cases.

they were probably offered the option to leave earlier via the chutes

Well that means leaving your Jimmy Choos behind, together with all other personal possessions, then probably better to stay.

How long would it take to bring a set of stairs to the doors? HKG is quite a compact field, being build on partially reclaimed land, the Rotterdambahn at Schiphol it ain't!

Would a (partial ?) anti skid failure actually result in blown tires in normal circumstances ? I would think that you don't get close to max breaking capabilities in standard operations, even on an A380... ?
