RE: OZ 777 Crash At SFO Part 2

Sun Jul 07, 2013 12:42 am

Quoting FirstClass (Reply 191):
I can't help to think that this incident is similar to BAs 777 crash landing. The weather conditions were too good for a pilot error of this magnitude. In both cases the plane came down short of the runway, though the BA flight didn't loose its tail, which indicates a completely different angle at impact.

What engines do the Asiana 777-200ER's use? Hopefully, date from the FDR and CVR will tell us why the plane ended up flying so low (especially with ILS turned off due to taxiway maintenance).

With all caveats about the accuracy of flightaware data, & the following may be a red herring, I've plotted the altitude and speed for the Asiana aircraft along with ANA8 (77W) and UAL852 (772) that arrived shortly earlier, all vs latitude. T/D is the nominal touchdown point on the runway (37 36'45" = 37.6125) .

What stands out is that the Asiana aircraft is about 300ft higher than the other 2 aircraft until about 1500ft where the speed is reduced and keeps on reducing.

It was originally announced that landings would approach over Millbrae and land on the 1's? Is that stillthe case or are landings coming over the Bay on the 19s? Sometimes in a big deal like this reports can be conflicting. I was planning on going to Millbrae for some evening plane spotting. Can anybody give me some details of the flight ops out of SFO this evening including which direction are landings and departures? I'd appreciate it.

Thanks. I had not seen that photo yet. I do agree it hit the seawall, then. All I'd seen up until then was photos that showed a debris trail heading back up the runway from the crash site, but nothing that actually showed the lip and/or any damage to the seawall.

I mean, I know the inference can be drawn fairly easily since there was debris in the water, but I still hadn't seen anything specifically showing it.

Very true, but then, how often do 777 pilots fly a visual approach with no guidance but the window? Usually, even when flown visually, there will be an ILS tuned, or PAPI or something to cross check against. Perhaps to much time looking out the window for guidance meant they didnt realize the speed was dropping off? (Please no one get angry, I am just positing an idea)

There are now some police? officers walking in the runway and the grass area. Looking for the FDR and CVR?

Typically police officers are there to secure the scene and have little, if anything to do with the actual crash investigation. They will assist in search and rescue for survivors or casualties alongside the fire rescue crews. They're also there to make sure evidence does not go missing. Much like with a crime scene, a crash scene needs to remain as close to the way it was when the crash happened.

Assumptions on my part, but the left side of the aircraft slammed down after the tail strike, causing the left engine, all flaps (except for the flaperon) and the tip of the left wing to shear off (see the image in reply 53). The engine is probably somewhere in the grass between the taxiway and 28L.


From a post I made earlier:

Quoting srbmod (Reply 40):
It looks to be in the water right before the seawall, as based on the images being shown on TV, there is something in the water there that looks a lot like the top of the engine pylon. If so, perhaps it hit the jetty/seawall first, sheared off and fell into the water as the rest of the plane moved forward. The debris field starts right at the end of the runway, so it seems likely that the #1 engine impacted the jetty.


If you look at the following photo from the CNN website, you can see what I am referring to:

The fact that the tail got broken off like would seem to indicate it must have hit the sea wall with a low speed and a very high angle of attack. So the pilot was pulling back to try to avoid the wall but there was not enough speed or power to climb. We don't know why not yet, but it reminds me of the BA crash where the pilot pushed the throttles foward but the engines didn't respond. It's the second time a 777 has hit the ground hard during landing just before the end of the runway after an unproblematic long haul flight. The fire must have started after the crash because fuel leaking from the tanks would have come into contact with the hot parts of the engines.

I'm sure you'll agree having all of the info available to us that we do, we know that this was a powered flight all the way down to when the flight touched earth, quite unlike the BA incident. There would have at least been a radio call by one of the pilots if it wasn't. So in that respect, it was unremarkable.

FAA lifted SFO ground stop.

However massive reduction in capacity with the shorter runways 19L/R in use.

Planned arrival rate is 10/per hour and departure rate also 10/hr.

FAA estimates they can raise this to 18/18 in about 4-hours.

Estimated average delays - almost 6-hours.

Are there no security cameras at SFO aimed at the approach end of the 28's? I remember when the FedEx MD-11 crashed and the only video we had available to actually see what happened was a security camera.

It's a major airport; there are plenty of cameras. There should be some footage somewhere if the cameras were pointed in the right direction, though the accident happened at the very far end of the runway which is quite far from the terminal and the tower, so the footage might not be great. Who knows if the public will get to see it, though.


Great, now the press found a passenger who is finally leaving, some poor Indian guy, and they're badgering him as he's walking away. He's just trying to get out, hasn't even talked to his family yet, has a broken collarbone, and the TV crews are shoving microphones in his face and shouting questions. He's being very nice to actually try to answer them.

It was unremarkable in that the flight crew did not make any remarks about it - they did not have any technical difficulties. If you read my theory about what happened (see posting #214), you'll find that we both agree that the final descent was indeed NOT unremarkable.

Looking at the following picture taken before the fire engulfed the fuselage, I'm noticing severe buckling/separation of the fuselage from the leading wing root over the top of the fuselage.

I'm speculating if that's from the front of the plane smacking the runway after the tail hit. Assuming of course that the tail strike theory is right.

Don't know if this was already mentioned.... but a woman staying at the Mariott across from the landing runways, said, to her, it seemed that Flt 214's "right wing struck an airport vehicle, and that caused the plane to filp around".

I know that doesn't make much sense.... I'm just reporting what someone else said.

If this is the case don't understand how a professional pilot makes a mistake like this. Of course other factors could be involved but none showed up on ATC.

Eyewitness statements from laymen are notoriously unreliable. In addition this person had no instruments and a side view. As any pilot will tell you, the senses can easily be fooled and if you don't have instruments you have no way of evaluating sensory inputs.

Quoting Gatorman96 (Reply 76):

Could severe wake turbulence at the wrong time contribute to an accident like this? An ANA 77W landed right before AAR214 and eyewitnesses (insanely unreliable most of the time, I know) reported that the approach was unstable right before touchdown.

Everything is possible, but a 777 is a rather heavy contraption and would not be greatly affected by wake turbulence if separation minima were adhered to.

Battery power for half an hour of operation is a certification requirement. Of course the batteries are not sitting under the cockpit seats but as evidenced by this crash and the BA one they still worked after scraping the fuselage along the ground.

Can someone who knows how to post on of those altitudespeed graph type things that google earth can create off flightaware data? This would give some interesting info as to what was happening in the final phase of the landing.


Note that this is constructed from flightaware so is probably not entirely accurate.

Let's PLEASE stop the idle speculation and irrelevant comments. Idle speculation and irrelevant comments are for TV "journalists" to make.

I suggest that unless ***verified*** and concrete new info comes out ( unlikely in the next few days ) let's not make WAGs about the cause(s). Maybe confine comments to issues like operational impact to SFO (diversions/delays) or examples of stupid comments in news?


Yes, this was a very scary event. But let us not go into full "airnutters" mode, folks.
Quoting 802flyguy (Reply 196):
Again PLEASE stop the silly speculation!

This argument comes up with pretty much every crash thread. Here's the deal: We speculate on this forum. There's nothing wrong with it as long as posters separate speculation from fact.

Of you don't like it, this is not the thread for you.

On a side note, if you think this kind of speculation is inappropriate and annoying, stay away from YouTube comments. That stuff will melt your brain. http://www.youtube.com/watch?v=8kBLM-6dUGs

RE: OZ 777 Crash At SFO Part 2

Sun Jul 07, 2013 1:33 am

Summaring latest reports(speculations) in Korea,
my opinion about the cause of the accident is
1. horizontal tail in collision with breakwater due to
- sudden drop of the aircraft (maybe engine thrust was suddenly lost) : engine problem. it reminds BA accident in Heathrow.
- failure in horizontal tail
2.Belly Landing as there was landing gear problem
3. Malfunctioning of landing system and thus using 28L which is operated by manual
4. Optical illusion by pilots.
Landing spot of OZ aircraft was not normal, far front, almost near breakwater and the around as debris show.
The most critical clue is communications between pilot and control tawer. they know what problem was before landing.

Thanks for that graph. Definitely seems unstable on final. Rapid variations in vertical speed that close to landing is not good.

Quoting DIRECTFLT (Reply 236):
Don't know if this was already mentioned.... but a woman staying at the Mariott across from the landing runways, said, to her, it seemed that Flt 214's "right wing struck an airport vehicle, and that cause the plane to filp around".

The Marriott is a mile away. Unless she was watching with binoculars, I doubt she could have made out an "airport vehicle". Furthermore, there is zero evidence at this point that there was another vehicle involved, either from news reports, or any of the photos. There IS, however, plenty of indication that the seawall was struck.

Could it be possible that it is similar to the accident on BA38?

The BA38 flight on Jan 17, 2008, en route Beijing-London Heathrow by a 772ER, crashed at landing due to engines failure

Update: 2 dead; 1 unaccounted for according to CNN.

It also looks like the second engine is on the airport grounds according to pictures from CNN. It is unclear though the location of this engine. Can anyone tell?

Look at the 8th picture: http://edition.cnn.com/2013/07/06/us...o-plane-crash/index.html?hpt=hp_t1

My guess is that they can in too low, then the pilots realized late pulled up and striking the empennage into the seawall and ripping the man landing gear off, or striking with the main landing gear (ripping them off) then the empennage. From the pictures, there is no sign of the main landing gear, only the nose gear that is on the runway.

From passenger accounts, the engines were spooled up right before the impact, this alone puts to rest any concerns over icing in the fuel system (ala. London Heathrow 2008).

Speculation:

Scenario 1: Altimeter was set wrong. Flightaware radar data when compared to other flights landing on the same runway minutes before OZ214 they were about 200-300ft below glideslope consistently.

Scenario 2: They were on visual approach misjudged the distance from the runway.

Scenario 3: Stalled at the last second or got a stall warning and the pilots over-reacted by pulling up sharply while increasing the power to the engines instead of just adding power and dropping the nose a degree or two. Looks like there are a pretty good drop in airspeed, so if this data is accurate, there could be some truth in this scenario.

This has already been brought up. Also, BA38 was not engine failure, but rather fuel contamination leading to restriction in the fuel flow through a heat exchanger.

RIP for the two who lost their lives but on the more positive side, well done to all the crew for safely evacuating nearly all of the passengers. They saved alot of lives today.

Runway 28R must be totally checked for ANY debris or items that could be related to this tragedy, no matter how small. If there is anything, it may NOT be removed ore handled until the NTSB gives the OK to do so. Then that runway must be completely inspected for any damage that it may have sustained and repaired. The runway will need to be cleaned to remove anything, accident related or not, before the runway may be used by any aircraft for taxing, taking off or landing.
Runway 28R could be closed until tomorrow. I am not an aviation expert, but the safety of all aircraft using that runway is item number one.

This has already been brought up. Also, BA38 was not engine failure, but rather fuel contamination leading to restriction in the fuel flow through a heat exchanger.

According to passenger accounts, the engines revved up right before the impact. This would rule out any association with BA38 as the engines were running and starved for fuel

CBS is already comparing this to the BA crash saying they are very similar.

Two numbers I will be very interest in hearing are the accumulated hours in the 777 by the crew.

Two witnesses I think we'll be happy to have: The Captain & FO in that UA 744 that was pointed right at the 777 as it approached.
