Oh dear this really does not make good reading....

What's factual so far...

1) The crew attempted to salvage a landing from an approach that was a hundred levels above unstable.
5 miles out at 3,000ft!!! Bearing in mind OPKC is only 100ft above sea level!
The speed and rate of descent needed to make the runway from there just boggles my mind

2) Both engines made contact with the runway and it seems to be confirmed now that the gear was never down. This could be explained by Airbus pilots who have confirmed that the gear lever can be moved to the down position and remain there but above 260kts the gear will not extend. The only way to resolve this is to recycle the gear and lower it again.
Given what had to have been going on the flightdeck at the time and all the warnings that would have been going off like crazy, very possible this could have been missed

3) Warnings are sounded on a priority basis so a "Too low gear" that would normally alert the crew to the fact the gear was not down and locked would have been suppressed by a higher priority GPWS Pull Up or Sink Rate. Its certainly possible given the way this approach had to have unfolded that the crew simply saw the gear lever down and assumed the gear was down, even if at a late stage they got a too low gear warning. One can only imagine the profile and energy this approach would have involved.

4) Its simply not conceivable that the crew could have made the approach knowing the gear was not down or they had a problem with it. Gear not locked down is an emergency every time, they would have had to notify ATC and would have never attempted to complete this approach in this way with a know gear issue. The only way you would ever try to land from an approach like this is if the airplane is simply not going to keep flying any longer due to a catastrophic event.

5) Once the aircraft hit the ground - confirmed now by video of the runway the engines would have taken all the impact. The long scrape marks on the runway indicate severe and prolonged contact, this would have caused major damage to the engines of course. Its extremely plausible that oil started streaming out of both engines as a result of impact damage and the subsequent total loss of engine oil would have resulted in the engines failing. We know from the ATC recording that the engines were still producing thrust after the go-around, the thrust can be heard increasing during the readback by the pilot.
That the engines failed so quickly with no prior warning certainly lends credence to the idea that a rapid loss of oil led to failure with no warning.

We shall have to wait for official word of course, but a number of facts have been confirmed today by authorities in Pakistan. What is beyond dispute though is this crew confirmed that at 5 miles out they were still at 3,000ft (should have been 3,000ft 10 miles out and at 4DME down at 1362ft according to the chart), this approach was never once stable and frankly it should have never been attempted. An unforgivable attempt to salvage a landing from an approach that was so far outside the envelope as to be in another solar system. The only way they could be excused for trying to land from where they were, was that the aircraft was a burning heap or was so uncontrollable that they only had 1 shot at getting it on the ground.

Sad, tragic and completely avoidable.
