Passengers can be seen evacuating on video.

Images showing both engine and gear clearly off the aircraft.

Its reported that the aircraft was departing and there is no FR24 track so it looks like a botched aborted take off?

From the CAAC
The pilots had interrupted the takeoff in line with procedures after experiencing an abnormality, CAAC said in a statement, leading to an engine scrape and fire after the plane veered off the runway.

The Twitter pics seem to show a MLG and an engine on one side of the field and the rest of the aircraft on the other after significant metal to concrete connection.

90º steering again?

90º steering again?Designed to avoid exactly this.

[DaveReidUK]

Designed to avoid exactly this.

I don't think 90º steering is a design criterion ...

[FlightDetent]

Correct, only +/- 75° is. FCOM-DSC-32-20-10-A.

#16 sounds like a complaint about this feature: https://mentourpilot.com/incident-a320-lands-with-rotated-nose-gear-again/ (feature, not a bug), hence my call.

no evacuation on starboard side?
Did flames start after port side evac commenced?

on one of the images the starboard aft door is open and the evac slide deployed almost horizontally,

You see pax coming from the nose of the aircraft but hard to see if they come from the forward port door … this door is seen open in another video but not clear if a slide was deployed there …

the plane is flat on its belly so the jump is not as high as could be, but,

one website was reporting 36 injured yesterday,

and a substantial fire on the fwd port side before it was put out with the help of about 7 ARFF vehicles..

Fun fact; RTOs are not practised in the sim in China...

[Nil by mouth]

The evacuating pax not carrying their hand luggage unlike westerners in similar circumstances!

Really? That sounds weird, after all it is one of the few maneuvers that need immediate action (and possibly a control transfer) without any real time to think, therefore it needs to be trained regularly.

[FlightDetent]

Fun fact; RTOs are not practised in the sim in China...Oh don't you say...

Not true. Don’t know who told you that but in my outfit we definitely do it 4 times a year; Every 6 months during training day and check day.
Edit: I asked one colleague who used to be captain with Air China which is the national carrier and they also do rejected take off in the simulator.

[BoeingDriver99]

I sit corrected; my outfit don't do 'em.

no evacuation on starboard side? Did flames start after port side evac commenced?

The video quality is not that good - but it is clear the flames only start on the port side during the evacuation. The L1 slide is out and almost flat. A number of passengers are on the slide and one jumps over the side. At first it looks like there is a vapor behind the middle of the slide (as seen from the front). Then suddenly a flame start roughly between the middle of the slide and the wing. With the initial flame still below the wing leading edge level. In the next video the flames are already up and forward and to the side. This all before the ARFF vehicles arrive. Both aft slides were out too but you dont see anybody getting out there (but the video is not that good).

Pretty clear from this video that a even a short delay can kill ... re delays caused by people trying to get their carry on bags ...

On the other thread, a report of two explosions heard and fire around the port wing. Perhaps the port engine let go, and/or massive loss of thrust, with the other on full chat and they couldn't control the yaw.

[FlightDetent]

That implies them trying to fly her away. Okay, selecting toga would match that plan AND exacerbate the yaw, possibly taking the aeroplane off the runway before getting airborne.

However, I'd expect the destruction to be much more severe with a high energy excursion at around 140 kts if that had been the case.

For a stop decision, the asymmetrical thrust is quickly removed by the initiating THR IDLE/REV.

[BoeingDriver99]

It could be an engine failed approaching V1 and they selected TOGA initially and then Idle/Rev. Using TOGA for a V1 cut is all but mandatory in some airlines and as the V1 speed approaches the skipper should be go minded -> large audible stimulus -> reflex action to select TOGA -> massive and increased yaw -> RTO initiated -> max braking pointing 20-30 degrees of runway centerline -> crew along for the ride.

[Uplinker]

I was thinking more of an engine failure at a much lower speed, well below Vmcg, so not enough rudder to help.

That sort of yaw has occured when pilots don't wait for the engines to stabilise at 50% thrust before selecting FLX/TOGA.

I am not suggesting that happened here, but it could have been a low speed (IAS) engine failure.

[Boeingdriver999]

Any updates on this event? No initial report seems to have been produced as far as I can see?

nothing to see here, move along ...
