On Sep 15th 2023 the airline reported, that following the go-around the crew was monitoring their fuel usage which was fine. Only after crossing the point of no-return to Omsk the fuel quantity suddenly began to critically decrease about 70nm short of their top of descent. The crew did not wait until fuel was exhausted but began to immediately prepare for an emergency landing, spotted the landing site from the aircraft when only 5 minutes of fuel was left and landed with 200kg of fuel remaining.

So either a malfunction in the fuel measurement system (after a malfunction in the hydraulics—very shoddy) or a fanciful story. And still wondering why they choose to divert with two good hydraulics systems, flaps, gear, #2 reverser and alternative braking available. More questions than answers.Originally posted by Gabriel View Post

It seems she is about to take-off from there...

Waste not want not. I'll bet a ruble they actually attempt a soft field takeoff.Originally posted by Gabriel View Post
It has now become clear that that the hydraulic failure happened AFTER the go-around decision and had nothing to do with that decision. The gear retracted but the doors remained open. That tracks.Comment

And........the Russian information pendulum swings back again.......Originally posted by Gabriel View Post
Diversion decided AFTER the hydraulic failure. I'm back to asking why? Maintenance facility at Novosibirsk? Didn't want the a/c stuck at Omsk?Comment

Some insight to that in the latest AvHerald update:Originally posted by Evan View Post
On Sep 26th 2023 Rosaviatsia reported during the final approach to Omsk, while extending the landing gear, there had been a green hydraulic failure prompting the crew to initiate a go around. The landing gear lever was placed into the up position, but the landing gear did not retract according to the FDR data, the failure of the gear retraction however was not noticed by the crew. While holding near Omsk the crew calculated the landing distance and calculated the fuel needed to divert to the alternate aerodrome followed by the decision to divert to Novosibirsk. While enroute to Novosibirsk the crew detected the increased fuel consumption and lack of fuel to reach Novosibirsk, selected a landing site from the air and landed there with 216 liters of fuel remaining. The failure of the hydraulic system occurred due to a fractured hose in the control line of the right main landing gear door.

So... in this latest swing, there was a green hydraulic failure when deploying the gear, which shouldn't have prevented them from landing at Omsk although the go-around was wise. And then... if this report is at all reliable... they flew to Novosibirsk with the gear down and the doors open the entire way until suddenly noticing the increased fuel consumption situation.Originally posted by Gabriel View Post
If true, thus is clearly a crew with zero understanding of the A320 hydraulics.Comment

What is the indication if you move the landing gear lever up but the gear doesn't go up?
I assume 3 green if they remain down and locked or red if they are in any position other than down and locked or up and locked (lights out).
And an ECAM message for the gear disagree?

Moving the lever puts the gear in transit, so the locked status should transit to unlocked and you will see the red UNLK (or UN) lights above the green triangles. Of course, if in doubt, you just bring up the gear page on the SD. That will also show you the door positions.Originally posted by Gabriel View Post
But it seems that this crew didn't put two and two together. Systemically, a failure of the green system means no gear retraction. As for landing on the intended runway, all you are losing is the #1 reverser and the nose wheel steering. So you could safely land and stop but not exit the runway (although it might be possible to steer off the runway with the remaining accumulator pressure, since the priority valve has closed to isolate the gear breach).
I would have expected them to go around, work the checklists and inform the tower before landing on the destination runway. Maybe they would have needed a tug. That would have been the end of it. So, I think this one illustrates that ON TYPE systems knowledge is essential for safety. Or that Russia is still giving us fanciful accounts of this incident.Comment

I’m getting wind of a hairbrain scheme to take off from this field. They’ve cleaned the dirt and straw out of the engines and removed any excess weight including the pax seats. Next they have to find a crew condemned to a Siberian gulag (maybe the same crew that landing it there) and offer them a chance at freedom. And a good amount of vodka to get them into the cockpit. Not looking forward to this Special Takeoff Operation.Comment
