EK 777 DXB - IAH RTO 8 August

[seagoll]

Anyone know what caused the RTO today on 12R on the Houston flight.I hope everyone is ok.Apparently all 12 tires flat,so perhaps high speed.Fire trucks in attendance with steps.

[flaphandlemover]

Technician told me:

High speed rto due to tire problem on nosewheel....
subsequently high speed RTO... Fuse plug melted and 12 tires to be changed...

well done all of the involved :ok::ok:

nothing to see... just move on..

[Fubaliera]

Ek or Qr 777

[Townie]

"12R"

That's got to be EK.

"High speed rto due to tire problem on nosewheel....

Anybody knows what kind of a "tire problem on nosewheel" ?

[seadouble]

Well done to the Emirates IAH flight crew!

[Payscale]

The kind of problem you dont want to take in the air...

[atiuta]

lol...inflammatory statement.

wrong guy in the CM1's seat, should have been the junior one....wonder if he took the sandwiches home?

[McGreaser]

Well done boys and girls...........just another day in the office:ok:

[EGGW]

Right, the dross has been been removed. CI999, has left the thread.

Any rubbish will be deleted.

[Payscale]

Sandwiches??!!! dont get the point..

"The kind of problem you dont want to take in the air..."

Payscale, can you be more specific ?

From Boeing FCTM 8.20

Tire Failure during or after Takeoff
If the crew suspects a tire failure during takeoff, the Air Traffic Service facility
serving the departing airport should be advised of the potential for tire pieces
remaining on the runway. The crew should consider continuing to the destination
unless there is an indication that other damage has occurred (non-normal engine
indications, engine vibrations, hydraulic system failures or leaks, etc.).
Continuing to the destination will allow the airplane weight to be reduced
normally, and provide the crew an opportunity to plan and coordinate their arrival
and landing when the workload is low.

[fo4ever]

Probably not the smartest thing to reject for a suspected nose wheel tire failure nearly at V1.

Probably not the smartest thing to enter a 100 tonnes on the low side as TO weight.

No one got hurt, so well done.

Hope that this one does not result in more "resignations"

Lets see - "Just Culture" at Emirates - we all know that.....

[Marcellus Wallace]

Good job no one got hurt. :D credit to the crew on the day.

Not sure what speed the RTO occurred at. Presuming the airplane was heavy to IAH and if it was Field Length Limited, it normally takes 60% of the runway to accelerate to V1 and 40% left to stop.

Easier to speculate from armchair - nose tire failure, all engines running, if practised in the sim - continue take off - leave gears down to avoid damage, come back for landing on 100% of the runway? If main tires failed the 40% left to stop may not be enough taking into account loss of braking effectiveness with the failed tires.

Just another point of view.

165 or so kts, BOOOM right under one's arse, aircraft swerves a bit, tyre bits fly into the e and e compartment giving some weird EICAS, destroys the downlock sensor......what to do? You got a second and half to decide. Engine failure? Tire failure? Or what? The right answer is probably either stay on the ground or go fly. Book answer probably one should go fly, real life answer with a second and a half analysis, stay on the ground with sensory information given. Interesting thing is, that thing stopped with around 300 meters remaining. That's what's impressive. Sadly, there may be some extra training for these chaps refering to the above Boeing FCTM. "Of course you should have known it was a tyre failure".:ugh:

[fourgolds]

All you arm chair warriors make me sick.

How do you know what the crew experienced ?

How do you know that the vibration / bang / noise etc as a result was not so severe that the aircraft appeared " unsafe or unable to fly " as per the reject policy above 80 kts.

Sadly I suspect the compamy will throw the book in their faces if it was just a tyre failure. Man this job sucks at times.

I am so happy to be in the company of all you arm chair professionals that get it right all the time . Lets see , BOOM , BANG , YAW , SEVERE VIBRATION !!!! , " I know what that is , its trye failure" , GO ( contuue) , YEAH RIGHT !!!!!

[alwayzinit]

I believe the FCTM is referring to a main gear failure,IMHO.

A Nose wheel exploding is going to throw debris all over the place........and highly probably down both engines.

As 4 Golds says Big BANG, Big YAW.

I know what I would probably have done, lets see what the investigation finds out.

If there is any signs of ingestion in either engine then it was not just a good call it would be a great call to stop rather than take possibly 2 dodgy engs airbourne.

[flaphandlemover]

huge dents in the lower skin of aircraft aft of nosewheel....

I don't know what you guys are talking...

Great job and right decision....:ok::ok:

crazy to always tear everything a apart and what you would have done...

have you been the augmenting crew? If YES, then you have the right to speak if no...

SH:mad: THE F:mad: UP:ugh::ugh::ugh:

Well done all of the involved:ok::ok:

[IXNAT]

Look flaps, nobody is slagging the crew. It's called "hangar talk". We all learn from others' mistakes or correct decisions. The event is discussed, dissected, reviewed and put in one's tools of decision making. Just because there is discussion does not mean what the crew did is deemed right or wrong. Relax a little. At that moment in time, perhaps 100% correct decision. Maybe the next time it will be a few knots closer to V1 and it would've been the wrong decision. Who knows today. But we all learn from a healthy discussion and analysis. No one on this blog has said, these guys had their heads up their third brown eye or what they did was not smart. It appears that guys want a healthy discussion so when they are faced with a similar decision they might have more information to make in their case a good decision. Just chill a little and let the discussion ensue. Again, just hope the perfumed princes can relax a little too.

[MrMachfivepointfive]

Thing is: There is no aural warning: 'Hello, my name is nosewheel and I just blew'. There might not even be a 'bang'. All you have is a massive, sudden vibration of uncertain origin. Nothing wrong with that crew's reflexes.

Taking flaphandlemover's advice - let the following speak.

Some old timers might remember an EK A300-600R had a nose tyre failure at V1 one night at MTOW (about 15+ years ago). Tread seperated and hit under the E&E compartment so hard all three IRS's failed :eek:. All screens blank after the bang so take off and return continued on standby instruments :ok:

[fourgolds]

to the crew involved , sandpit is right I recall the event too. if you need a defensive argument when you are facing the "panel" , it might be worth adding this to your arnsenel. good luck guys.

[Payscale]

Dont think there will be an inquiry. Crew is flying again.

[The Turtle]

just my 2 rusty cents here...so you're barrelling down the runway, you're a few knots before V1, you hear a bang, the aircraft pulls to one side. Maybe you have time to look at N1, maybe you're too busy trying to keep it on centerline.

appears a lot like the V1 cut we do every PPC to me, except it happened a second before V1. They did just what most (if not all) of us would do in that situation.

but that's just me.

[mensaboy]

Maybe that crew made the best decision, maybe they made the second best decision but the fact remains that they stopped the aircraft and no one was hurt. Congrats to them.
