Lufhansa 787 Collapse at Frankfurt

Can't see how this could happen... That will be out of service for a while

Boeing, boing.

Could have been a very bad day for the ground staff. Crew too, tbh.

I suspect given the bay doors are open, and there is someone looking directly at the gear it was a case of the doors are jammed open which was followed by "just throw that lever up and down again to cycle the doors"....

You can't park there mate....

But thank goodness it went whilst almost static and not when coming in to land or take off....

There is a hole to put a pin through when throwing the lever. It’s apparently easy to put the pin in the wrong hole, as BA found out a few years ago.

A variation of 'The front fell off.'

99% it's going to be "sorry guv, stuck it in the wrong hole"

There was a local standby at Gatwick when a warning of nosewheel not deployed came up on the final approach for a 757. The plane was sent back to the stack, then told to fly past the control tower and bank so the boss there could get a look at the nosewheel. I was by one of the RV points, just inside, talking to airfield ops crew, all relaxed as it was not that unusual and voices were ultra calm on the air. Then the message, 'nose wheel not fully deployed. Repeat not fully deployed'. It looked alright to me but then I knew nothing. Upgrade to full emergency.

It was then back to the stack and those planes on approach landed and the rest were diverted. Fuel dumped, the plane came in, on full flaps and various other bits extended. The nose was up. It looked great, remarkably different, right up until it came past the 'sheds' to the east where the winds could be frisky. The plane jumped all over the place. That's when, I was told, the vomiting inside the aircraft started. The main undercarriage touched down early and then, with nose up, it came along the runway, quiet and slow. As it approached where I was standing, the nose came down slowly until it was a couple of feet from the tarmac. The engines were 'gunned' (there's probably a special term for it, but I'm not interested) and the nosewheel, noticeably bent up, kissed the ground. The nosewheel jerked back and the plane rolled slowly to the end of the runway where it stopped, closely followed by the fire service.

All was quiet for a while until an airfield vehicle trundled out, a sort of 'cherry-picker' was raised, and for the next ten minutes the pin was hammered into its hole, the sound echoing. That's when the screams started inside the plane evidently. It was inspected by people in suits, and then the plane was towed to a remote stand.

I'm told the pilot kept the passengers informed, 'We will be banking to the left past the control tower . . .', probably not as reassuring as he hoped, but forgot to mention the pin. Three times on approach and being blown about all over the place. They were probably a bit touchy.

I was told that when an aircraft is to leave the stand, before it moves, one of the ground crew has to wave the pin, which has a flag on it, so the pilot can see it. It is not unknown for planes to wander off with the pin still there, but there's some warning sign that comes up on the pre-flight checks as it's not a good idea to have it still in when retracting it.

One of the most impressive bits of landing I saw. The aircraft went beyond horizontal while moving down the runway. Weird. Even the airfield ops bloke, who'd seen it all, stopped breathing until the snap-back. We patted one-another on the back. Equally weird.

That's quite interesting. The range of knowledge on PH never fails to Impress me.

So why do they put the two holes so close together? (Keep it clean)

[butchstewie]

I think it's as simple as there are procedures so they assumed nobody would get it wrong.

Remember it happening a few years back and when you see the videos/reports you just think it's accident literally waiting to happen.

I'm more interested how it happened again but aerospace does seem to have a bit of a habit of making recommendations like that "optional" from what I understand.

[alangla]

It’s not even so much that it happened, it’s that it seems to keep happening. There’s pics on this thread of a plain white 787, an Ethiopian one (they do seem to have more than their fair share of Boeing mishaps), the Lufthansa aircraft that’s the subject of the thread and obviously BA had an incident with one 5 years ago. I wonder how many Dreamliners have suffered this misfortune over the years.

[andy43]

Awww. I think it’s just a bit sleepy.

If they can do it for petrol and diesel nozzles at a petrol station, this seems bizarre.

How was it ever signed off?

I think the 737 Max shambles probably explains that.

Look at how those pins are inserted. They do look to be different sizes to me.

And sure, it's impossible to misfuel a car.....not.

One is a pivot/bearing point, and they probably thought that anybody with the job of putting the pin in would know how the nose gear works and that it would be obvious. Presumably that was not the case, or the tech was under time pressure and just got it wrong.

The fix was to put some sort of blanking plate/pin in to make it impossible to do that.
