no-one knows ...

until someone does it and then there'll be the mother of all investigations

But a 787, on the other hand, subject to the same forces, clearly isn't going to just crinkle prettily - and if we're not talking about replacing frames, stringers and skin panels, what are the implications ?
I think we might find that the 787's bendy bit is different than than the 767's bendy bit, but I think the end result will be similar. I'm guessing on the 787 that the landing gear will end up absorbing the impact to the point of either full or partial failure.

Will be interesting to find out. I wonder if the flight control laws have any protection for this, or if they could be written to provide such a protection. :confused:

You guys should all stand back and ponder the fact that a jet NEARLY came a cropper in a manner similar to the purple one, in similar conditions, at the same airport.

You can argue about windshear and sink rates speed excursions until the cows come home but this was a nasty bit of work.

The crew, the airline and indeed the wider industry should feel guilty. People have died many times in accidents in similar conditions because pilots are too scared to divert or too scared to carry extra fuel or too scared of the boss or think they are better than they really are.

There are extenuating circumstances of course, but it is not good enough to argue that the forecast changed and put the crew in a corner. This simply should not occur.

How much fuel did they have? How many options did they have?

If conditions were as per the ATIS, the METAR and several prior actual reports then this approach was conducted in contravention of company SOP’s, manufacturers SOP’s and common sense.


“The typhoon was supposed to last out only until 2300z initially but carried on for a couple of hours more than expected.”

You would have to be a lunatic to fuel plan a flight into a typhoon based on a forecast to within “a couple of hours”.

“Just a bad day I guess..With a decent ending.”

A broken aircraft is a decent ending? No, it was a LUCKY ending.

“You are telling me that every time you get a 15 KTS gust report you divert? Give me a break!”

According to Airbus in case of actual or suspected windshear you must “delay or divert”. Its fair to say that in the above situation, windshear was suspected. And the results proved it to be so. I suspect maybe the Boeing manual indicates something similar.

An jet is badly damaged and maybe written off and the response from some here is that its ok, nothing to see hear.

Crazy.

AnQrKa.....

Quite right. Although having mentioned something similar last night the 'Gestapo' was after me.

There was no excuse for this.

Lucky outcome but a string of bad decisions leading to a likely unstable approach followed by a terrible landing and a bent airframe as a result. Not to mention, the poor folk down the back that were involved.

As for the 787, only time will tell how the composite airframe handles such stresses IF its unlucky enough to end up in such a pickle.

Has Gestapo gone back to Flight Sim 2004 to try it out perhaps?

twochai 21st Jun 2012 19:39

Looking carefully at the video, I think you can actually see the fuselage deflecting in bending, perhaps as much as four or five degrees!

How much fuel did they have? How many options did they have?
ANA dispatches their flights very conservatively, I wouldn't doubt (as a matter of fact, I'm pretty sure) that given the circumstances in terms of WX, they had enough fuel to go back to PEK if they needed to, how about we stop assuming that they were cornered into making the approach, that is just silly, the dispatchers are very proactive in sending us turb & windshear reports constantly, there is no hidden company culture here that would have prevented them to divert if they needed to, stop making ridiculous assumptions without all the facts:=

Composite material
 
Not sure if this thought will answer your Q?
The famous Studebaker vehicle is a good example: when hit from different angles particularly front and back if it was metallic, the metal will shrug or show signs of fatigue; if it was fiber glass or composite material, it would break.
Based on the video provided on Japanese T.V it appears to me as if the fuselage would have broken in pieces leaving all passengers exposed to a more dramatic incident. However, the B787 has some strings interconnecting the fuselage parts attached, and it has a damper that makes passengers and crew ignore certain G's in-flight. Would this concept apply on the ground?? I am sure Boeing considered this possibility, they certainly made better landing gears on B747's compared to Airbus A380's, and more so, better and safer aircraft compared to English "aerocraft" manufacturers. :)

The famous Studebaker vehicle
The Avanti, I assume you mean? Hardly a "famous Studebaker vehicle," but never mind...

Then you might as well shut down aviation in Japan because we have those kind of conditions at least 25% of the time here. Nothing in my Boeing manual says anything near that. A windshear warning, yes, but a simple report of windshear, no.

That's quite a lofty assumption


If conditions were as per the ATIS, the METAR and several prior actual reports then this approach was conducted in contravention of company SOP’s, manufacturers SOP’s and common sense.
Does your conclusion apply to everyone else who attempted an approach around the same, including the US and European carriers, or just the reckless Asian ones?

composite crash tests
 
I seem to recall reading about Boeing's 787 fuselage crash tests. The initial tests were a failure because the composites shattered (rather than crumpling). I think a honeycomb structure had to be added in order to pass the test.
Anyone have any information on this?

How about actually reading what someone wrote, i.e. me, about the conditions when they did land, rather than going off half-baked on your crusade to castigate the airline industry and this crew in particular. If people have died in conditions when this flight landed then it was almost certainly not as a result of the weather and your suggestion they should have diverted is so far beyond ridiculous that I wonder if you know the first thing about aviation.

The conditions early in the day were not particularly pleasant, as Gestapo has already said. However, as I have already said, the weather at 1300L (when this flight arrived) was really quite benign. Their crosswind component would have been in the region of 15 knots and the the windshear that you seem to be so concerned about was no more than +10/-5 due to mechanical turbulence, not the well-past typhoon. I KNOW this because I landed only around 1 hour before them and those were the conditions when I landed. The weather only got better after that. The conditions were as per the ATIS and METAR i.e. no concerns whatsoever and there was no contravention of any SOPs. Read what Dominican has written about ANA's dispatch policy and you'll also understand this crew would have not been worried about fuel etc.

I suggest before you accuse all and sundry of breaking rules and flying in unsuitable conditions you do your homework first, rather than relying on the reports of someone who landed hours beforehand.

"The conditions were as per the ATIS and METAR i.e. no concerns whatsoever and there was no contravention of any SOPs."

If the WX was so benign as you state then why was the approach clearly so unstable. It surely rates as one of the most hair raising attempts at landing I have ever seen.

As AnQ stated, this aircraft was badly damaged. If it wasn't the wx, then what on earth is going on there in Japan.

Over to you wise one!!!

oicur12.again 22nd Jun 2012 01:58

And it would be interesting to see some METAR summaries from the arrival time.

Dignified
Your comparison of the Studebaker behavior to that of a Boeing 787 is a tad silly, in my humble opinion.
Fibreglas technology in the early 1960's compared to carbon fibre of now!!!, come on, get a grip!!!!

If the WX was so benign as you state then why was the approach clearly so unstable. It surely rates as one of the most hair raising attempts at landing I have ever seen.
Who says the approach is unstable? The approach obviously met with ANA's stable approach criteria (which is the same as just about everybody else) or else the crew would have gone around. How is it 'clearly so unstable'? All you see is the landing, so you have no evidence to support your inference. All you've done is assume the weather was bad, which it wasn't and then apply your false assumption to an imagined hypothesis that the approach was unstable.

What you do see in the news report is the short period before the flare where the nose is lower than a 'normal' approach, indicating the aircraft is likely to be flying close to, or at, the max speed of Vref+20. Shortly thereafter you see a very rapidly 'flare' which, in my opinion, is instigated too late, thereby rotating the main wheels onto the runway (very positively, indeed). The aircraft then bounced and, in my opinion, the pilot does the thing that we've been taught NOT to do from day one; he pushes forward on the control column. The rest is pretty obvious.

So, no, it wasn't the weather at the time of this landing that caused the incident but, rather, in my opinion, a late flare and a botched reaction to the bounce.......like you get 'over there' in the USA every now and again i.e. this has got nothing to do with Japan or the general standard of their pilots.

Capn Bloggs 22nd Jun 2012 03:03


Better video of approach prior to flare. First touchdown didn't look too bad to me; bit of an over-flare beforehand (well saved, IMO), causing the bounce. The big mistake was stuffing the nose down too much after the bounce.

Bearcat 22nd Jun 2012 03:11

His nose down pitch attitude at 100ft suggests maybe he was carrying excess speed. The snatch flare and subsequent hard nose over on touch is where the action begins.

Baulked landing on initial heavy touch down comes to mind.

Why? This aircraft is clearly marked with both the "Air Japan" and the "ANA" logos. I have not seen any indication as to the nationality of the flight deck crew.

Fratemate 22nd Jun 2012 04:34

EXLEFTSEAT,

NH956 is a mainline flight and not AJX (Air Japan). The crew were Japanese. The aircraft has Air Japan & ANA written on it because we (AJX) fly ANA's aircraft. The flight in question was an ANA mainline ticketed and crewed flight and not Air Japan.
