The gear did not catch fire. There was an RTO due to a tire sparating and causing damage to the aircraft. As a result of the heavy braking all main wheels deflated due to the heat and the fire service used water/foam to prevent any fire.

Emirates Boeing 777-200, flight EK-213 from Dubai (United Arab Emirates) to Houston,TX (USA), rejected takeoff from Dubai at high speed after at least one nose gear tyre burst. The airplane came to a stop about 2000 feet short of the runway end with both nose gear tyres burst, responding emergency services needed to cool down the overheated and smoking brakes.

The runway was closed until the aircraft could be towed off the runway.

The Boeing 777-200 registration A6-EWF resumed the flight departing Dubai with a delay of 8 hours.

Couldn't find anything on Pprune about this.

How long is the runway closed in such a situation and what happens to incoming traffic? DXB has 2 runways, right? So I guess it just slows things down.

Why did the tyres burst? Due to overheating or the harsh breaking?

Its only june in Dubai, and guess tyres should take much more heat! Unless the tyres were not in a good shape?

I could imagine the pax freaking out during the RTA, and hard braking. DXB's extended runways came in very handy in this circumstance, an investment that is worth every penny. If this happened a few years ago while the runways where much shorter who know what could of happened. The pilot would have no choice but to take the plane off the ground, and worry later of how to land the aircraft with blown tires.

The aircraft most of been very close to its maximum take off weight. I wonder what the load factor was on the flight ?

I'm sure the smoke from the nose gear also made the situation tense, not to mention when all the fire trucks arrived.

The plane's brakes, and tires where most likely replaced since the aircraft took off eight hours later. I'm sure they will pay extra attention to this on all their other aircraft from now on.

Hi all,

For those that had questions about the heat on the brakes here is a nice video from Boeing with the RTO tests on the new 747-8

I couldn't get the link for the exact video, click on the one with the title
747-8 performs rejected takeoff

The tyres are designed to deflate in the event of overheating of brakes beyond a certain temperature, such as during a RTO. This is to prevent them from experiencing an uncontrolled puncture/explosion which may throw debris up and cause damage to the aircraft.

I doubt they are any maintenence issues involved here.
