JAL 763 Landing Gear Falls Off When Touching Down

TOKYO - Tires on the two front wheels of a Japan Airlines plane came off as the aircraft skidded to a landing at a Tokyo airport Wednesday, an airport official said.

JAL spokesman Geoffrey Tudor said one man and a woman both suffered whiplash as the plane, carrying 222 passengers and crew on board, braked to a stop.

The JAL flight from New Chitose Airport in northern Hokkaido state was landing at Tokyo's Haneda airport when the incident occurred, Transport Ministry spokesman Kazuyoshi Furukawa said.

The Boeing 767 aircraft was at a standstill on the runway. Officials were investigating the cause of the accident, Furukawa and Tudor said.

Everyone on board had been safely evacuated from the aircraft, Tudor said.

A passenger interviewed by Nippon TV described a loud crunching sound as the plane skidded to a halt. NTV said the incident may have been caused after the tires burst.

Earlier, Furukawa had said that the two front wheels, instead of tires, had come off the plane


This sounds serious. Tires coming off a plane upon landing? Well, apparently on the 10 pm news, there was an airliner analyst saying that there is no way that a tire can come off a plane no matter how hard the landing is....... but the tires can burst.

Can't imagine what it would have been like to be on the plane when landing.

The JAL company rules demand that the tires on each aircraft be replaced within 400 takeoff/landing routines. According to what the JAL spokesmen announced, both of the tires were within the 150~200 times limit.

Does anybody know what rwy this took place in? I know that HND uses 16R, 16L a lot during the summer months (from my memory). Did this incident cause major delays?

Two tires falling off is way different than a landing gear falling off.

It landed on Runway 34L. It closed that runway for little over 5 hours.
It was a soggy day in Tokyo yesterday.

Does that mean that they opened 24/06? I have never seen a take-off from 34L.

I've never heard of this. Every operator I've ever worked for or with changes tires on condition. I can't even imagine tracking tire installations.

Absolute rubbish. I can think of a couple of reasons without even trying hard. The bearings may have failed or at the last replacement the wheel may not have been torqued correctly which would lead to a bearing failure.

Though it pains me to say it, it's probably a maintenance issue.

What came off? Just the tyre or the whole wheel assemblies? In the later case it could have been a bearing failure, and since it happened on two wheels, probably due to bad torquing during maintenance, as AIR2GXS said. Or they have forgotten to install the safety bolts in the axle nuts, or VERY TYPICAL on 767s, forgot to install the axle spacer and washer on reinstallation of the wheels (has happened before), causing the bearings to be too loose. Some airlines make the spacer and washer installation an Required Inspection Item, this means having a second person verifying the installation and signing for it.
Tyres get normally changed on condition, except if the plane has been parked for a loooong time.

Can anyone find out if the 2 (two) out of 222 that "suffered whiplash " were Japanese. Perhaps they did not have seatbelts on.

Not true.An AU MD had to come back to AEP a few years ago as one of the tires got off and rolled down the RWY.

Whiplash is a neck injury, a passenger seatbelt won't prevent that.
After Monday and Tuesday even the calendar says WTF...

Ktachiya,
If the winds didn't change, all arrivals would be on Runway 34R and take-offs on Runway 34R or 04.

Link to a picture showing the damage - those wheels look pretty bare to me;
