Come on!!!!! I know you all saw it!!!!!!
34l closed due to A330 stuck on runway.......
Where were the press with this one:ok:

Well if it only just happened it will be tomorrows news!

Nothing in the NOTAM's and ATIS reorting 34L & R Ops. Any more info? Surely not a total failure?:eek:

The continuing decline of the World's sharemarkets is taking precedence over any and all news events....even gear collapses on the Scarebus

Gear failure... lol

The gear was down and locked. However, there was a gear annunciator problem caused by one of the computers. However, the gear synoptic (or whatever they call it on the Airbus) was showing everything ok.

The crew thought they'd go through their checklists to be on the safe side and selected alternate gear extend. I'm told that this locks the nosewheel steering (huh? Don't ask me, ask Airbus). So the aircraft had to be towed off the runway .

The aircraft is relatively new, and computers are.. well... computers... so it's highly unlikely that this is a result of poor maintenance.

The aircraft did a few passes.... this also helped burn off fuel (less fire hazard).

Computer replaced... Problem fixed :ok:

Rgds.

Possibly a LGCIU fault. Should not be a big deal as there are alternate indications for gear down verification on all airbusses.

Don't be surprised if you get "Plane maker goes in stockmarket collapse" on the news. Some aren't exactly flush for funds

The thing to remember is the process or organising and then towing an aircraft from the runway can take a month of Sundays, so if you think there is a likelihood of a tow being required then please don't be backward in coming forward and let someone know. This should minimise delays to other aircraft and reduce the likelihood of following traffic being sent around or changed at short notice

PS On final is too late.

The flipper doors were still down though. Looked kind of funny.

flipper doors, love it. You didn,t fly an Italian jet at any stage did you?
AI say that as long as at least one indication of gear down is present, then land.

The said aircraft cleared ILS 34L then went around due to gear problems....
Aircraft sent out to he south to get its act together. It refused to lower its gear and crew had to complete a gravity extension.
Landed 15-20 mins later on 34L .
Had to be towed off runway as a result of gravity extension.
Press obviously too busy reporting on the recent spike in margarine prices or something just as important :ok:

Who are "they"? I spoke to an engineer working on the defect... and he said otherwise. He said that the crew cycled the landing gear several times, but kept getting the same faulty indications.

I believe it was an LGCIU fault, but Airbus acronymns are not my strong point :O

LGCIU- Landing Gear Control Interface Unit. The acronym sounds a lot more mysterious and makes better press for the un-initiated.:ok:

That's like the computer error that is so common. They call it an ID ten T error. When you write it down it spells id10t.

(no reflection on the people involved here)

They cycled the gear several times?????????

We are told never to cycle the gear, it may cause more problems.

On a 777 if you get a gear disagree message you just go straight to the altn gear extension. Boeing do not encourage cycling of the gear.:=

To quote the Boeing FCTM:

GEAR DISAGREE
Land on all available gear.
The landing gear absorbs the initial shock and delays touchdown of aircraft body
parts.
Recycling the landing gear in an attempt to extend the remaining gear is not
recommended. A gear up or partial gear landing is preferable to running out of fuel
while attempting to solve a gear problem.

ooohh touchy Airbus Pilot.

Ok, I just checked the Airbus 330 Fcom 3 and yes you are correct. It says to cycle the gear and if nothing then use Altn extn.

But cycling it 3 times?

So if you have a little time (and extra fuel), what's wrong with having a couple of tries? (Particularly if the QRH says "recycle", which obviously means it is not a danger to do so).

A wise man once said "Rules are for the slavish following of fools, and the guidance of wise men". (Thanks, "Starch") :E

This whole thread has turned into a wankfest. The crew had a gear problem, they dealt with it with a successful outcome - end of story. Who cares?

20th Sep 2008, 14:46
I think you will find the FCOM says cycle the gear so it can use the other LGCIU ie LGCIU2 this is a back up box for you none scarbus people

No, what we would like is for you to get your facts straight before you go sprooking your pearls of wisdom all over yourself! Silly silly boy:O:O......:D

Gee Captain I guess you're wrong!!

Love it.....guess the Cathay Command course can't teach you everything can it??:p:p

I don't mind admitting when I'm wrong, didn't need the command course in CX to teach me that simple piece of courtesy. Seems as a direct entry F/O you're command course might be quite a way off:} So enjoy the back seat for a while yet.


I still say that cycling it more than once is folly, and to my way of thinking against the Airbus Fcom 3 checklist. Do you think it's wise to cycle a landing gear that may have problems 3 times? Can't you see how it could be made a lot worse by repeated cycling? Do it once and then use the Altn ext.

OK this thread is getting silly. The procedure for the A330/340 is to recycle the gear to change the LGCIU over. If after one cycle this doesn’t get the gear down you do and emergency gear extension remembering that you won’t have any nose wheel steering after touch down due to the nose gear doors remaining open. Under no circumstances do you cycle the gear multiple times because after one cycle you have essentially determined the problem isn’t with the LGCIU’s but is most likely mechanical.

A380 - did you get a number plate and phone number done too?

21st Sep 2008, 04:30
The reason there is no nosewheel steering after an alternate extension is that all Green System hydraulic pressure to the landing gear is bypassed which allows the gear to free fall.
It is also the reason why gear doors are not retracted.

Correct.:ok:

:ok:Ok, for the benefit of Airbus 380:

Mr NSEU said in post #11Who are "they"? I spoke to an engineer working on the defect... and he said otherwise. He said that the crew cycled the landing gear several times, but kept getting the same faulty indications.

I then voiced my concern over multiple attempts to get the gear down citing our own Boeing proceedures and COMMON SENSE.

I then corrected myself AFTER reading the A330 FCOM 3 and ringing an Airbus mate

I then further said that I still thought 3 cycles was stretching the intent of the FCOM a bit. To which 404 titan basically agreed.

So you see, I didn't start the "cycled 3 times" suggestion.

So, Mr A380 man, get down off your high horse my friend.

ACMS
22nd Sep 2008, 06:48
Can you read A380????????????????

You probably think the A380 is a nice looking aircraft as well :D

Somebody ELSE suggested they cycled the gear 3 times.

To which I basically said "mmmmmmmmmm sounds suss, the Boeing manual says......."

I then corrected myself after looking at the manual AND discussing it with a very experienced ( 10+ years on the Bus ) Captain and corrected my post.

Although the 777 is a Boeing and the Airbus is a ..............well, Airbus they are still Aeroplanes with quite a few similarities. One is not to cycle the gear just incase it gets worse. The 330 allows ONE cycle to change to the other LGCIU. Repeated cycling of the gear is just crazy. Airmanship and plain good ol common sense doesn't change with the aircraft type.

Anyway..............you go back to reading and comprehension class.

And I'll promise to look deeper before I leap next time............ok :ok:

Indeed... and there will be an investigation into why the crew wasted so much time analysing the problem... and landed with only 2.7 tonnes of fuel.

If it was a broken brace or something, I can envisage it sticking in a fuel tank multiple times or breaking hydraulic lines.

By the way, Engineering told them if it's ok on the ECAM, then land. The annunciator lights use separate sensors... and a discrete card in the #1 LGCIU (only). Any malfunction of downlock sensors would have shown up as a message (there were none).

Maybe Airbus will add a comment about cycling the gear unecessarily in a future FCOM version :ok:
