Ural Airlines flight 1383 had to land in a field due to hydraulic problems and fuel shortage. The airline does not scrap it, but is repairing (source) and is going to fly it. A320 landing gear is not suitable for soft surface. How are they going to make it run and take off?

    $\begingroup$ "The airline does not dismantle it, but repairs and is going to fly it." - what's your source for that? The article you linked says that "given the location of the aircraft it is likely to be dismantled in place". $\endgroup$

    $\begingroup$ It also helps that they are presumably going to run at minimum weight / fuel. $\endgroup$

TLDR: cold winter will freeze the ground and make it hard enough.

First, there was a similar case of Alrosa flight 514 that landed on a disused runway in Izhma in September 2010, was fixed and flew to the closest airport in January 2011. So fixing a plane out of airport is nothing special.

The difference is that in Izhma that was a disused airport, and a local ex-employee had been cutting newly growing trees on the runway (summary), whereas Ural's A320 is sitting in a completely unpaved field.

But I'm from Novosibirsk and lived there for 30+ years, so I know how things work in that climate pretty well.

1. The ground freezes deep

By late January, the ground becomes frozen 1-2 m deep. That's why pipelines like sewer must be buried 2m deep in the region. Frozen ground is so hard that you can't dig it with a normal spade. To give a perspective: according to material stiffness tables, pure ice at -20°C is harder than pavement brick.

So, if the ground is even enough, there's no problem supporting one plane for one take-off run.

How do you make even ground?

2. There are winter ice roads in this climate

Winter ice road is built for winter months after temperatures become permanently below 0°C. You pour water to melt snow and the ground, even the surface, e.g. with a buldozer, let it freeze deep, and the road is ready. Climate in Novosibirsk isn't particularly cold -- there are much colder places in Siberia -- but every winter there's an ice road made over the water reservoir here.

climate chart from Wikipedia

Tempreratures near Novosibirsk are (almost) permanently below 0 from mid November till mid March. In January, weather is ideal: by this time, there's half a meter of snow on the field, enough to even the ground; anti-cyclones keep skies clear and temperatures low, around -20°C (which actually gives engines a boost in thrust).

Watering the field will actually make it freeze deeper, because ice is a good heat conductor, whilst snow is an insulator.

3. Isn't it dangerously slippery?

No, smooth slippery ice is actually very hard to make. People in warm climate think anything at < 0°C is slippery, but it's not. When I was 10-12 yo, I tried making a slide on a slope and failed utterly: I took a bucket of water and poured it on the ground, and the resulting surface was very bumpy like a sponge, you could almost walk uphill on it. Instead, to make a good icy slide, you need to smooth the surface beforehand and then carefully spray water, not letting it melt through.

Remark: cities in warm climate near the seas regularly have ice rain phoenomenon, when the air above the ground is below 0, but clouds masses are warmer and it rains rather than snows. I've never seen this in the middle of continent.

Only twice in my whole life there was a case when it rained in November same day as temperatures would drop below 0 permanently. Lots of stuff got covered with ice for months, and lots of sidewalks and paths in forests were like ice rink -- the first time, I was a schoolkid and we loved it! (BTW, salt won't help if there's lot of snow and temperatures far below 0.)

By the way, this ice wasn't forever, because it got gradually covered with snow. And normal snow isn't slippery at all, at least if it's colder than 0.

Icy surfaces in Siberia are very likely not in autumn, but in spring, when snow melts on the surface during the day and freezes at night.

So, ice isn't a concern at all. Plus, I believe they landed in this very long field (which seems to have no high-voltage line), so there's plenty of space for a stop in case of aborted take-off.

4. Won't it Damage the Field?

The field gets plowed every year, so bulldozing won't harm anything. Watering it will only do good, because the primary concern in this climate is to have enough moisture in the ground in spring. Dry winter with little snow is very damaging for agriculture.

So, How's the Plane Going to Fly Out?

The recipe, that I believe, Ural Airlines will follow, is this:

  1. Put the plane on hard surfaces, like wood or metal sheets.
  2. Even the necessary field.
  3. Water it regularly.
  4. Let the snow stay couple of weeks before the take-off, to make smooth and non-slippery surface. Compact it with heavy vehicles.
  5. Wait a day with clear sky, and fly the plane, like Alrosa did.

ADDED: replying to @U_flow's comment regarding costs and labor.

First, I don't know if the surface has big waves that may make the aircraft jump before flying. From the photos it looks smooth, and they may need only to run a tractor to finely grind the dirt. But if the landscape is bumpy, they'll need a scraper. (Elevation map shows there are bumps, but smaller than 5 m.)

Here's an aerial photo: enter image description here the aircraft under inpection, photo by Ural Airlines

Second, ice roads are made anew every year, without much noise -- which probably means they cost a tiny fraction of a normal road. The real question is where you get water for the trucks, when they're not on a lake, but in a field. They might need to run trucks to the Ubinskoye town in 10 km. (A temporary pipeline seems problematic, because if water stays still, it freezes and ruptures pipes -- so operations must be very cautious.) Or they can bore a new well -- ground water in that region is high -- although, the place itself is on 10m higher ground.

Route to Ubinskoye, OpenCycleMap

But once the dirt is frozen and sustains a truck, the rest must be easy. Snowfalls are frequent but drop just ~5cm of snow every couple of days, so a truck can work just couple of times a week. Here's an example of one:

enter image description here A random photo of such a truck, source

I guess, it should cost < $500K, which is 1% of what such plane cost before the sanctions were put.

    $\begingroup$ Out of curiosity, if the ice in fact dangerously slippery, wouldn't that likely actually be beneficial unless emergency braking was required? Since the wheels on takeoff are essentially just there to support the plane. $\endgroup$

    $\begingroup$ Good answer. My only query I guess would be starting the plane when it's that cold, but I would guess that is a matter of portable generators and engine heaters? Would increase the costs of the operation but as stated, I guess by not a significant amount compared to the value of the aircraft. $\endgroup$

    $\begingroup$ @ThaRobster in Novosibirsk, aircrafts are often parked for night, and I guess they must be cold as ambient temperature by morning. I didn't hear from pilots that it takes some special equipment to cold start them. In the worst case, there are "heat guns" -- big tube, large like suitcase, with conducting spirals that heat up, and a big fan. $\endgroup$

    $\begingroup$ "And normal snow isn't slippery at all" - this is why I hate when they pour salt on footpaths here in the winter, it turns it into an dirty slush that ruins your boots, instead of the perfectly walkable packed snow. $\endgroup$

Update - it didn't work :-(
News reports as of January 12th 2024 say:

  • "Ural Airlines has decided to dismantle its stranded A320 in a field in Siberia, instead of trying to retrieve it. The plane crash-landed in September 2023, but all passengers and crew were unharmed. The airline initially planned to fly the A320 off the field but reconsidered due to risks and technical difficulties, ultimately deciding to scrap it for parts.

from here

enter image description here

Also here

  • The Ural Airlines Airbus A320 that was forced to land in a field is to be dismantled, according to new reports. ... A Russian aviation Telegram channel, said that after a thorough evaluation has been completed, the decision has been made to dismantle the plane for parts and not attempt to fly the Airbus A320 out of the field as was previously proposed.
    Aerotime revealed that Ural Airlines pays farmer year’s rent for wheat field holding the stranded Airbus until spring 2024.
    The Ural Airlines plane remains in the field just outside Novosibirsk, in southern Siberia, protected by 24-hour private security in a fenced off area.

    $\begingroup$ My guess is the insurance company wouldn't cover the flight under the existing policy, requiring additional insurance for the flight. And I can imagine the lawyers cautioning about the risk of expensive lawsuits from the flight crew's family if it didn't work out. Even if as the accepted answer predicts the flight would have been relatively safe, comparing all of that to what they will presumably get paid from insurance by declaring it a loss, probably it just wasn't worth it. Not sure who gets the money from the sale of parts in these type of situations, maybe the insurance company. $\endgroup$ Commented Feb 9 at 3:54

    $\begingroup$ High demand and low availablitiy of spare A320 parts must have played a role in this decision. "We can try an interesting but technically challenging solution to preserve our wealth, and maybe learn a thing or two in doing that, or, who cares, we go after big money with a rapid export of parts from the field to the nearest airplane market-place". Looks like (western) Europe economic politics of the last 20 years :D $\endgroup$

  • $\begingroup$ I wonder, @StevePemberton, if the airlines (or Airbus') test pilots would be covered in a situation like that. After all, as a test pilot, one's family has the reasonable expectation that you'll not make it back from any given flight. (Sure, probably more likely to live now than in the 1950s or 60s, but...) $\endgroup$

  • $\begingroup$ @FreeMan - and of course the pilots themselves would have accepted the risk. But none of this would matter in a civil lawsuit which would be about about convincing a jury that there was willful disregard of risk for the sake of profit. Whatever caused the crash, the plaintiff's lawyer would attempt to prove that the airline should have foreseen this possibility and not attempted to save money by flying the plane out. The odds of this situation actually occurring and a lawsuit succeeding who knows, but lawyers giving advice tend to put an emphasis on non-zero risk and the possible implications. $\endgroup$ Commented Feb 9 at 17:19
  • $\begingroup$ It's possible the ground didn't freeze deep enough to make for a viable runway. The picture can't be older than late January, since the plane's fate was in the air until then, but the landscape appears to be just below freezing point. $\endgroup$
