AN-124 Uncontained Engine Failure

An AN-124 out of Novosibirsk limped back to the Airfield today due to an uncontained engine failure. The Engine almost completely disintegrated and some spectacular wing and fuselage damage.

Gear failure on touchdown resulting in runway excursion.

Appears all on board ok.

IIRC they have the main avionics bay in the upper deck next to the spar.

Makes the bi-annual 'engine failure after take-off' in the sim seem a little mundane!!!

Good job getting it safely back on the deck, I'm sure the dents will buff out and a bit of speed tape over the hole will see it good!

Edited to add: That's a hell of an egress ladder on the starboard side! :eek:

Wow, One of these diverted into MAN UK the other day, left yesterday. Glad it wasn't that one. Russians build em tough...well, not the engines obviously.

Russian forums reporting substantial electrical loss after an uncontained engine #2 failure coupled with a loss of engine #1 control, which remained on 70% thrust all way down including the landing roll, kept running after the aircraft went stand still.

Bit like that Qantas A380 it seems. Lucky escape again fortunately.

This is precisely why I never want to sit in that row of seating in any pax jet.

Looking forward to those pilotless aeroplanes.

Worth comparing to Cathay 780 as well where the crew were unable to control engine thrust and had 70 - 80% N1 on engine 1 during landing.

Touchdown speed would have been well in excess of normal and control very difficult with 70% N1 on an outbound engine. Almost certainly tyre failure followed by gear failure, possible hydraulic problems as well given the extent of the damage.

Looks like an excellent job by the crew.

I wonder if they did the standard 3 minute engine run-up on the threshold prior to departure?

From the pictures it seems like the N1 rotor cartwheeled over the top to the other side.

Or maybe it went through the cabin. Great job by the crew. That must have been a handfull.

Good video of the overrun.

Take off here plus various clips of landing.

The pilot's description of the incident, as quoted by Oleksiy Sokolov on 'Mentour Pilot':

Quote:

The second engine exploded and cut electric wires, so we lost all the electricity. And we returned to the aerodrome of departure on an airplane having a total electric failure. We lost all the communication, both intra-cockpit and with the ATC. We just gained 300m altitude at that point. We were a crew of 6, and other technical crew of 8, they were in the rear cabin. We took a decision to return to the aerodrome of departure, visually, we tried to establish visual communication but that didn’t work. We took a decision to land on RWY25, since it was a critical situation and we took a decision to land as soon as possible. Since we didn’t have a lot of altitude and excess of thrust too. There was a complete electric failure, brakes didn’t work, reverse didn’t work either since the wires were cut. The landing was soft, there was no damage during the touchdown, all the damage was due to the runway excursion. The gauges in the cockpit didn’t work, from the angle of attack we figured out the speed was about 280, it was a calculated airspeed. We haven’t even raised the flaps at that time, just raised the gears and we heard a bang. We still had control, but the electrical system failed completely.

I am reminded of ASN Burbank DC-6 1976 where a prop blade went through the fuse and took out the opposite engine and hydraulics.

Kudos to the 124 crew:ok:

Nobody would l like to be in this situation, but the curved APP, possibly even sideslip to counter thrust and keep descending at correct angle, ( if I interpret the videos clips correctly ) a prefect touchdown , then wait until it stops and get everybody out unhurt deserves big respect .. Those guys knows how to fly.

Good job it was a VMC day !!!
