Delta aircraft loses a part of the wing
A Delta 757 loses a part of the wing, wonder how bad it would have been if the engines were rear mounted

@tiger: the passenger who took that pic is a boss :D
|
Wow right along the attachment line on all sides. When they find it they might even be able to reuse it if the attachment holes were mostly empty.
|
@lomapaseo : I'm no expert but I'm surprised that some of the wires didn't come off
|
Loss of wing panel @tiger9999187
Wow, did the gear extend ok, major hydraulic leak on that right main gear ram!

Material
They could make the wing piece from Perspex!!Then you could see things working!!!
|
Fortunate it did not do some stab or elevator damage.
|
first time I've seen something like that. :D
|
Plane was Delta 2412 KMCO-KATL.
|
At a moment like this, keep calm and carry on! where was it going, I wonder, and how high when this photo was taken out a passenger's window....that's somebody I would call a very first class passenger!
|
Are we being misled?
It looks like an access panel removed for inspection. Edit: major hydraulic leak on that right main gear ram! Why is there a test kit attached to the ram? |
The image looks real to me at least this posted version, the jpg tiles match up between the wing & sky....
No jaggies seen, no errors noticed on the static discharge? protrusions (trailing edge, outside wing) The photo would need to be taken & processed in raw mode & then converted to a jpg to give the same effect, but the noise levels look very similar between the wing & sky i.e. same camera used... Of course no EXIF data provided... Could be wrong, but.... AND..the oil spray looks very realistic! :) |
Can anyone here tell from the ram whether the wheels are up or down?
|
Gear is up.
|
It looks like an access panel removed for inspection. I assume a ferry flight without that panel is not allowed? Some mechanic will probably have a chat with his boss now... |
The image looks real to me at least this posted version, the jpg tiles match up between the wing & sky.... As someone said, it is a lot of screws to be left out/loose. |
The upward curve to the wing looks natural and strongly suggestive of in-flight loading, owen meaney.
|
Yes indeed it does, cheers Cameronian.
Should have looked online first: http://www.news.com.au/world/delta-p...-1226857236107 |
I suppose an ETOPS (or whatever it's called these days) wouldn't dare shed a panel like that over the middle of the pond. :eek:
|
Owen, the hydraulic fluid (called "skydrol") is pink/purple to make a leak easier to spot
|
There must be an embarrassed person out there with a pocket full of fasteners.... :E

Once upon a time, many years ago, I boarded a Delta jet at SFO somewhat early. I had a seat on the aisle in an emergency exit row. I was just making my nest when three Delta employees showed up and asked the lady in the row across from me if she would mind getting up for a few minutes. She got up and they proceeded to open the exit door (it was a lot heavier than I would have thought) and all get out on the wing. They stood there looking down at a small access door about six to ten feet out from the fuselage and then one of them, presumably the mechanic (engineer to non U.S. readers), took a roll of duct tape (aka speed tape) out of his overalls and proceeded to carefully apply tape along the edges of the door, overlapping both the door and the wing. He stood up, the other two (presumably an inspector and a supervisor) nodded their heads, and they all clambered back inside. It took a little jiggling and manhandling to get the door back in place but they did, thanked the lady, and departed the airplane. Passengers kept boarding through all of this.
The folks on that side of the jet kept the rest of us informed as to the condition of the duct tape all the way to Dallas... |
There is just a slight difference between speed tape and duct tape. If you don't believe me, go out and buy some speed tape but make sure you have a bank loan in position first.

Are we being misled? It looks like an access panel removed for inspection. Edit: Quote: major hydraulic leak on that right main gear ram! What color is hydrolic oil? Why is there a test kit attached to the ram? The gear would still come down under gravity extension if the ram doesn't work. It looks like there are a few sheared fasteners on the edge nearest the window and on the aft edge nearest the window, possibly job started and not handed over properly. Composite panel would rip right off on take-off although I'd expect it to pull over the screw heads rather than shear them off. Great photos from the passenger though! http://avherald.com/h?article=471862b4&opt=0 |
I would image a fair bit of force on that panel during flight...someone calculate that for me....
weight of the aircraft/wing area would give the weight per square inch then multiply by the area of the hatch... What's the number? |
.. afew tons I expect!
Nobody has even said yet what type of aircraft it is... Wasn't it Delta debris that supposedly ended Concorde's career, quelle chagrin! |
@harryman : It's apparently a 757

Unlike MIL-H-5606, which leaves reddish stains wherever a leak exists. Best indicator of a slow leak or seepage of Skydrol on the outside of an aircraft is to find deteriorated / bubbled paint. It's a better paint stripper than chemicals specifically designed for that purpose... |

What's the number? Firstly, its only the top skin missing, the underside of that area is still contributing a large percentage of the lift that it would produce, if the upper surface was intact. Also it is apparently about 60% chord so aft of the CP and flow disruption may well be quite minimal. In all it probably had a far smaller effect on L/D than you might imagine As for the percentage of structural strength of the wing it contributes, would, for me be a guess, so I wont bother....OK I'll bother...< 3% |
Too much De-Icing? :}
What would be the fuel penalty factor with such a hole?! |

HarryMann it was a Continental DC10 not any DAL aircraft.:)

I hope the crew amended the Zero Fuel Mass before landing, otherwise the calculated landing mass and the load/trimsheet would have been inaccurate?
Tea but NO biscuits with flight management! ! ! ! := |

Unannunciated checklist
Wonder how much they added to V ref for that one !
Still speed taping hatches on newer airplanes |
Seems like this sort of thing happens to Delta a lot more often than the other US Legacies.
Their older fleet is starting to creak a little. |
I think if the mechanic forgets to put the screws back in, the age of the aircraft has little bearing!
|
Stilton, if you had read the article fully you would have realised that the panel normally is never removed as it is fitted with a mixture of hi-loks, rivets and fasteners. Only Boeing know why there is that mix, with a hydraulic leak a burst of pressure could push the panel up and off where the leak is situated, remember the pressure is approx 3000psi.
