I really hope this was a case of unexpected slippery runway.

Lately everything is about fatigue, overworked pilots, stress and time pressure.

Would be nice to have a common weather related problem this time.

Can we assume touchdown was at about 20:55Z?

Heavy sleet shower reported, with very poor visibility to the north-east (i.e., on the approach to Rwy 24), an RVR of 600 metres, and cloud broken at 300 ft. IIRC, braking action of 0.32 is medium-poor.

Aircraft appears to be substantially damaged.

Thanks as usual, Kulverstukas. Actually, that photo of the R/H main gear (aircraft pointing from left to right) does not look too bad.

But, in addition to the apparent collapse of the nose gear, the previous ones suggest that the engines may have ingested soil, etcetera. That partly depends on at what point the engines were throttled back to idle, at what point reverse was cancelled, and at what point they were shut down. (Presumably full reverse would have been used for the landing.)

Can we now have a 5 page discussion as to whether the aircraft should be towed out or powered out? Only, I've got bored with the EASYJET thread!

So, crap vis and a slippery runway, and if the tracking data is to be believed, and orbit at the start of the approach. That could have been to avoid a small patch of weather, but is more likely to have been to reduce energy. It'll be interesting to find out what speed and height profile they had on intercepting the approach and where (and if) they met stabilized criteria - it may be that they were stable early on and have been very unlucky, but the orbit raises suspicion of a rushed, high energy approach. I hope for the former.

If it's a genuine one... Suspicious lack of snow... Oh it's +2C here as a local guy reports.

More to the point, I trust the flight crew calculated IFLD (In-Flight Landing Distance). The A321 is a slippery beast, reversers are generally not much use, and the full length 2500m runway was definitely going to prove tricky with the 0/0 temp split, 12 knot crosswind, +SNRA and medium/poor BRAKING ACTION.

The QRH landing performance calculation shows that it was marginal at best, (IFLD comes to 2350 m, assuming low landing weight, CONF Full, Autobrake MED and a fully serviceable aircraft with no MEL items to affect. Factored Landing Distance, as advocated by Airbus, is 1.15 *IFLD, which comes to 2702 meters, over 200 meters longer than the full runway length. LDA is doubtless down to around 2200m, so an overrun was inevitable). Aquaplaning and/or temporary loss of directional control due to employment of full reverse would lengthen the landing run substantially, causing a yet longer overrun.

Standard winter conditions for that part of Russia though, but never easy with a slippery jet. And if the approach was a few knots fast, therein the problems really mount up.

And why would anyone "hope" that it was weather-related rather than fatigue of the pilots. Such a stupid comment, given above. Not a professional pilot.

Kaliningrad is not really part of Russia, it's an accident of history.
As we all know it's part of the Baltic states/northern Poland region, and it's not standard winter conditions currently either.

FYI current weather is really quite ferocious with a first winter storm over the whole region - a winter depression currently centred over exactly that area in Lithuania, + heavy icing in the Baltic sea off Helsinki wave height 2-4m.

Wind swung from SW to E to N in a matter of hours.
Ask me how I know!

Outside temp -12C the wind adding a further -10C to it.

Not true. Kalingrad is absolutely part of Russia.

It's just an exclave, that's all, just as Alaska is an exclave of the US. (Some would argue that Alaska is really a pene-exclave, but at that point we are just splitting hairs).

A/c still sits at the ground. Airport authority seriously discuss possibility to call Navy for help.

How would the Navy help? Salvage airbags?

What I would like to know and what is relevent is the situation with preceding landings? Had someone else just landed successfuly or maybe diverted with med-poor field perf?

It won't be the first time someone has made a complete b..ls up of landing a plane at KGD.
Last time it was a Boeing 737300 back in 2008.
