Qantas Blown Tyres on its 747-800

[Flying Fox]

Well according to this article, QF already have the 747-800 in service and its blown some tyres.

The 747-800 jet's flight from Sydney to Canberra was aborted after the tyres blew as it began take-off about 6pm.

Anyway, glad that no one was injured!

The SMH reports that tyres blew as a result of the aborted takeoff (in addition to getting the model right)

Tyres blow as Qantas pilots abort take-off - Travel - smh.com.au

Nearly 100 passengers on a Qantas flight from Sydney Airport endured tense moments last night when pilots aborted their take-off, resulting in two tyres being blown.

Deflated tyres are a common result of an aborted take-off. The tyres get very hot under heavy breaking and have pressure release values to deflate the tyres before they explode. Its interesting to see this commonly reported as "tyres blown on take-off", rather than what is generally more accurate as "tyres deflated as a result of aborted take-off".

I was commenting on the difference in the stories:

The Australian: Aborted takeoff due to tyres blowing
SMH: Tyres blowing due to aborted takeoff

The SMH article seems more accurate to me.

Ignoring the 800 part,
a 747 SYD-CBR ??

Indeed that would seem to be most reasonable assumption.

The 800 part is likely accurate. Surely there is not much difference between a 747 and a 737 Its only one number different :-|.

Very true. For the sake of selling a few more papers they ignore the fact that this is a design & safety feature.

If anyone is interested, in the Boeing 777 DVD box set, there is video footage of this being tested for 777 certification. The aircraft is taken to take off speed before the brakes are fully applied. Then they taxi the aircraft to a safe area and let it sit for 5 mins before the fire crews are allowed to extinguish the over heated brakes.

Result, all tyres deflate safely and alloy wheels melt. Reported cost is approx $1M USD to replace all wheels & tyres.

Isnt this the same incident type as the LAX "Qantas passenger in runaway terror ordeal" not long ago?

I can't believe that there have 7 posts in this thread and not one mention of outsourcing of engineering

Yes, it is not uncommon.

And no mention of the beer consumption in the QP while awaiting an alternate flight :shock:.
