What are the chances that Pakistan tries to sweep this under the carpet? Isn't the airline government owned? For some reason, I suspect we may never get the full story.

Jump to postThere would probably be engine oil on the runway if the oil lines had been severed and oil was being pumped out.
Fuel as well, but that would evaporate rather fast.
Given the A320 MLG cycle vids, it's hard to believe there was a gear cycle anywhere around the time the engines were close to, or touching the ground without badly damaging the MLG doors.
Jump to posttax1k wrote:If the engines scraped the runway for 1000+ ft wouldn’t that have thrown off sparks noticeable to ATC and/or other aircraft?
I have seen no reliable information that the crew ever reported a gear problem, or ever requested help with a gear problem, or ever tried to work on a gear problem, before attempting to land. It was in the AvHerald initial report Do you mean this?: "had aborted the approach to Karachi due to p...

If we take the runway marks at face value, then the engines hit the pavement about 1,000 feet apart along the runway.
Wouldn't we expect both engines to hit at about the same spot if the gear was raised too early and the landing was level, but simply too far down the runway?
Is it possible the nose Gear failed? Looking at a few photos of nose Gear failure in the A320, shows that the engines would have made contact with the runway. http://www.chinaaviationdaily.com/news/53/53971.html Well, there is no visible damage to the nose gear area. So you would have to speculate ...
Jump to postPoster at PPRUNE says that mode-S altitude never went to zero on the first attempt at landing, meaning there was never any weight on the wheels?
No idea if that's true.
If reports of the runway marks are accurate, It seems like the engines slid along the runway for several hundred feet, though.
It wasn't a touch and go, it was apparently a long-ish slide down the runway.
I don't think the gear was ever down.
I have seen no reliable information that the crew ever reported a gear problem, or ever requested help with a gear problem, or ever tried to work on a gear problem, before attempting to land.
Jump to postYou would certainly tell ATC if you had gear trouble and you'd certainly want to have emergency services ready if you are attempting to land with doubts about the landing gear. You're completely right. But also we have seen cases where pilots try to hide things from ATC with fear to expose some com...

Does the lack of gear door damage eliminate gear collapse and early gear retraction?
Jump to postPlus, the gear appears to be down in the last video. So it was apparently still in good enough shape to extend after the go around.
