Looks like tire failure to me
Don't think so. A single blocked/damaged tire wouldn't change significantly the direction of motion on a 777 .

Yes, because a tyre failure will do that... :confused:

Any link to the video
Thanks

Looks like tire failure to me. I'm almost sure of it, as seen from the black smoke.

Well if aybody can view the video, how sure are we of chicken vs egg regarding the smoky tire?

Black smoke from the nose tire as well???

Why did the film stop there??? There has to be about 15secs of useful footage left.

Crews who fly regularly in and out of MUC know that the Localizer on this runway (both directions) is very easy to deflect. As soon as something approaches the antenna, the signal does this S twist.

I fail to see a tire failure. If you see that your autoland doesn't guide to on the correct path, switch it off and go manual.

Looks like that plane spotter finally released the vid.

My pure observation:

Well, you can see the plane:

1)Last 30-20 feet suddenly bank left, left main wheel touch down first and HARD for quite awhile before right touch down. AC more to left of runway centerline if you observe the tarmac visual.

2)The black smoke is from the Grass debris kicked up from left main boogey going on it first BEFORE the nose wheel.

3) Nose wheel RE-airborne for 1-2 seconds and land again eventually hitting grass debris (coincides with attempt go around when nose veering off ?)

The whole veering seems quite linear rather than a violent swing. (more like JAY CHOU initial D mountain SIDE DRAIN-LOCK smooth Drift.:ok: He saved the day.

Around the 17th second is the nose being pulled up...??!
Also no reversers, even at idle? And I don't see the ground/spoilers either.
Something not right here.
If the vid is to be believed, aircraft never got into 'ground' mode. And then an attempt to abort the landing vs someone stepping on the brakes maybe..?!

Wow, you guys will make excellent accident investigators ! So observant and so sharp, right down to the micro seconds... I have informed Boeing and SIA to look you guys up for your expert opinions, advice and conclusion to the incident... By the way, cj has been pretty quiet lah.. No bitching for a while lah...

O'Neill No6 10th Nov 2011 16:07

Thanks for the video.

Can anybody see whether the speed brakes extend? Couldn't be sure. If reversers not deployed (as someone else noted) and speed brake not armed there wouldn't be an awful lot of friction to control the aircraft as it commenced it's detour.

Glad I wasn't on board front or back!

shinkai744 10th Nov 2011 16:08

Think CJ is being investigated by SQ. Might have bark up the wrong tree this time round. Let's see what happens to the guy. Becoming tougher or perhaps digging a bigger hole for himself.
Interesting nevertheless.

lomapaseo 10th Nov 2011 16:15

I thought the observations above were spot-on.

As to what caused them ?.... just speculative.

Back to the orignial tire-track photo.

Could The appearance of the sharpish swerve be due to fore-shortening from the camera lens distance?

rain5 10th Nov 2011 17:17

no
 
No tire failure

Precautionary change by MUN eng after event.

mrdeux 11th Nov 2011 04:01

Does anyone who is familiar with Munich know if the taxiway just prior to the initial excursion to the left might have been of interest to the crew?

Accidental TOGA push followed by a, 'I have control, no I have control, no the auto-pilot has control,' moment. Anybody wanna wager?

thks for the link

Nosewheel was firmly placed on runway then a new rotation commenced, which was abruptly cancelled.

Think that might be close to the truth. Last time this happened a certain 747 ended off the runway in BKK.

Oakape 11th Nov 2011 10:18

It might have been simply an attempt to get the weight off the nose wheel to avoid damage when the aircraft went into the 'rough'.
