THAI plane’s tyre bursts after landing

Recommended Posts

Not a specialist in the field, so just asking:

doesn't the picture show that the burst occurred on an area where severe abrasion had taken place? Like if the brakes had been applied before landing instead of while in contact already, meaning the wheel was blocked during contact?

edit:

some replies addressed the same question meanwhile I was reading/typing..

THAI officials said it was not a burst but just the tyre deflated after landing.

I didnt know deflated tyre could make a noise of loud explosion .. another lies from officials to save their faces ? This kind of tyre issue happens very often . no need to cover up .

As an ex pilot heavy landing or debris on runway, no need for all the I don't know armchair sleuths.

Absolute bullshit.

May I ask why, if it is so "absolute" for you?

No ploblem - the tyre has been sent out to Somchai's garage and is being repaired will be used later - why falang worry too mut

Thai Airways plane's tyre bursts after touchdown, no injuries reported

PNSOC561105001000101_05112013_031743.jpg

BANGKOK, 5 November 2013 (NNT) - According to reports, A rear tyre on the right undercarriage of Thai Airways International flight TG 130 burst shortly after the plane touched down on the runway at Mae Fa Luang airport in Chiang Rai province on Tuesday. No injuries were reported.

The incident occurred about 9.29am, reports said.

After the incident, the captain guided the aircraft to a parking bay without further incident and all passengers were safely disembarked.

Reportedly, THAI staffs are looking into the cause of the incident and the tyre was replaced.

Reports further stated that the THAI board chairman has come out to say that the tyre did not burst, but only "deflated" after landing.

Pretty easy to see that the brakes remained locked on this wheel, and the tire was dragged in one position until the tire burst from lack of rubber. Not unusual to have this happen, but unusual to make up a story about what happened. Interesting to see what a 4 month investigation will unveil. Overweight stewardesses???

Well spotted Stoli. Even a blind man can see that.

If the wheel was locked by defective brakes how come we can see the site of the blow out? Just asking and seeking an intelligent answer.

Don't expect an IA from somebody at Thai Airways or the Transport Ministry / government!!!

Could be as simple as a defective rotary transducer on the axle of that particular wheel, sending intermittent data to the electronic brake system control unit.

For example, if brakes were applied heavily too early on touchdown (before wheel spin-up signal, 50-60 knots or so) and locked wheel protection not working. The wheel would then start rotating freely once the pilot released the brakes after landing roll.

Or same kind of scenario with heavy breaking during landing roll and anti-skid not working.

THAI officials said it was not a burst but just the tyre deflated after landing.

I didnt know deflated tyre could make a noise of loud explosion .. another lies from officials to save their faces ? This kind of tyre issue happens very often . no need to cover up .

Heat generated by the tire can cause a tire to "deflate" in this manner even without this kind of visible damage. A long taxi distance at heavy takeoff weight, followed by a rejected takeoff at high speed will do the trick, for example. Stay clear and wait for about 10 minutes. Goes off like a stick of dynamite...

BTW, judging by the picture, we're not looking at damage from debris or simply a heavy landing (could be a factor though).

The wheel could have been locked on touchdown, due to a combination of poor technique (pilot nervously applying brakes early due to landing long, etc.) and a failure in the anti-skid system, but not by one factor alone. If the wheel was locked due to brake system failure alone, it would have stayed locked all the way to a full stop (and would have blown up before coming to a stop). No bullshit in the above, just normal curiosity.

Notice the large flat spot around the "X" of the rupture? That's a brake lockup / anti-skid failure. Check the runway for debris.

I used to feel pretty safe flying Thai... they sure are having quite a bad year. Sabotage?

The pilot can't lock one wheel. So an ABS failure on the failed assembly is more likely, since the other tires look fine (without being able to see all around the tires). A bit of investigation is warranted.

Correct. It is not possible by pilot error alone. Requires a brake system component malfunction to go with it. Or no pilot error, just "normal" heavy braking and component malfunction. In any case quite common. This is how you would find out about a brake system problem, usually. Check anti-skid fault codes, check wheel transducers, check brakes for freedom of rotation, check anti-skid valves, check wiring for damage, etc. If nothing found, replace and bench test anti-skid controller. Nothing in this incident is directly implying poor maintenance (even though that is probably also true).

The tire pictured in post #8 is "flat spotted" through at least a dozen plies. This would be due to the wheel being locked during touchdown (malfunction of locked wheel protection) or wheel locking during braking (anti-skid malfunction). It has nothing to do with "pilot technique" or how hard you brake. It is a system malfunction, plane and simple...

The fuse plug in the wheel is of no use for this kind of damage, as heat transfer to the wheel is required before it can work. Fuse plugs work well for excessive heat generated by the brakes not the tires. In this case the heat generated by the tire skidding would have taken a few minutes to heat up the nitrogen the tire is filled with, causing the pressure to increase and the weakened tire to blow out on taxi-in (normally within 15 minutes).

I'm no aviation expert but I was thinking the same thing. (tire locked up) You can see the flat spot on the tire clearly.
