Please have a look at this picture and read the caption.

My question is: is the A320 (A321) nosewheel supposed to bend like this or is there something wrong with this particular nosewheel?

I'm off for a few days, but I will ask one of our engineers what he thinks of this picture when I get back to work!

In the mean time I hope that someone can give me an answer here.

At least I already know now why to limit the speed during tight turns!!!

Regards,
Erasmus.

This is in fact normal for the A320-series and other planes where the nosegear leg isn't exactly vertical to the ground.The leg slants forward and this means the outer wheel will lift off the ground in tight turns.

Now,at OSL,Airbus 320-series planes are pushed back a little further from the terminal during pushback than other planes.It is said that this will eliminate undue strain on the nosewheel by reducing the need for very tight turns away from the terminal.So maybe there is an A320 nosegear leg problem.But not the reason for what's happening in the photo,though.

FBU hit it. The DC10 nose gear and Md80 nose landing gear are the same way.
This design has saved some people tires changes!!!  Big thumbs up

As a little funny note, it is quite fortunate for ex. when you have to check the tire pressure on the nose gear of f. ex. an md80, because sometimes the valve is hidden behind the spray deflector....a good trick is to take the tow bar and pull it sideways (as in a turn) and you can then freely turn the wheel to a comfortable position!  Smile

The DC-9 is the same way. FYI, TWA rolled an MD-80 off the end of our runway 01 on landing a few years back. Landing long, high, and fast, tried to make the last left taxiway exit he could, the nose wheel turned, right wheel on gear lifted off the ground, left wheel skidded, MD-80 went about ten feet into grass.

Not only jets do that...

The ATR's do the same, and plenty others too, I'm sure...

And my guess is: if it does it, then it was designed to do it, and it's normal that it does it...  Smile/happy/getting dizzy

Well, I read this topic lucky enough before my spotting trip to LHR.

When I was there on the terrace, I looked at the nose gear of all the A320's being pushed back there.

And indeed, almost all had this! Aswell the A321 of LH, the A320 of IB and the A319 of LH, together with most other A32S aircrafts.

Frederic

Thank you for the replies,

Of course the nose gear leg being slant forward explains the "twisted" look during turns.

Why didn't I think of that?

Erasmus.

I know a person who had an accident while towing an Md-80 in the rain. He made a tightish turn (which was required to get into the overnight) and the md-80 kept on going forward, dragging the pushback with it.
