I'm surprised this hasn't made it to a.net yet, but at 12.40 CET an Iran Air Airbus 300 skidded off runway 19R at ARN.

In Swedish, with a pic:

No one was injured. Apparently this happened very early in the take off run. Speculation is if a break was on the lmg, or if the #1 engine failed at spool up. The captain stated he doesn't know how this happened

The passengers have been evacuated and taken back to the terminal.

Considering it's what, 500m maximum, from the runway's threshold, the Airbus has gone quite a long way off the tarmac. Glad everybody is safe and well.

Thank goodness it was a such low speed, and the ground was frozen hard. That is a long way to go off a runway.

This looks very strange. So far off so early in the take off and the pilot doesn´t know what caused it. The snow clearing and runway breaking action is almost always excellent even in winter at this airport which is used to snow and ice so one can start wondering...

We are of course free to speculate given what we know right now. The preliminary findings could take days or weeks. Maybe there was a problem with the nose wheel steering? Below 80 knots thats the way to keep aligned with the centreline.

Judging from someone who claims to have been on board, the 1# engine seems to have suffered a compressor stall.

That shouldn't directly send it off the runway though, so we'll see what comes out of this...

My comment:
Passengers hear a lot of things when such things happen. I think a talk to the pilots could rule that out.. If the pilots didn´t know what happened a compressorstall seems less likely. The pilots would have known... The ATC tonight told a SAS-plane they suspected something was wrong with the landinggear such as main wheel brakes or something. By the way the plane is still there and the runway remains closed.

Well, it's not the end of the world; it's just an overrun; not much in the way of (apparent) damage to the aircraft and no serious injuries. It should be flying within a week or two, after it's been checked out.

The normal complement would probably be two in the cockpit and 10-12 in the cabin, so the remainder could be security personnel, although 10-11 seems like overkill (for want of a much better word!)

They carry two full crews on this one. One for the flight Teheran - Stockholm and the other crew for the flight back.

Pilots are highly trained to deal with technical issues and malfunctions. Depending on the investigation it very well could be their fault!

Let's allow the Swedish and Iranian investigators do their jobs and not blame the pilot(s) just yet. The Iran Air pilots are quite familiar with snow and ice: both Tehran airports, as well as many other major Iranian ones, are prone to severe winter weather.

The pilots could have done something wrong and there could be technical issues but noone is blaming anyone before any conclusions are made from the investigators. Since braking action was good and weather was fine this probably had nothing to do with it being winter conditions. It was not slippery according to airport authorities and it seldom is even during winter at ARN.

It seems to have been engine failure that caused the plane to skid of the runway.

A movie showing the engine 'blow'. Don´t know what happened to the engine expressed in more technical terms, but it broke.

Pictures in newspapers clearly show a flame from the left engine during take off. This indicates a possible powerloss on engine nr 1. It seems the reports from passengers was right this time.

But why couldn´t the pilots stay on the runway once the lost power on nr 1? Breaking action is reported as good...

I'm no expert, but I think it might be because of loss of thrust on one side and take off thrust on the other? The pilots would have taken a couple of seconds to cut power to no. 2. Again, I don't know, just guessing.

If the #1 (left) engine suddenly falied, as it appears in the video, and the #2 engine was still at full or near full power, the assymetrical thrust would be enough to make the aircraft veer to the left and run off the runway before the pilots could regain directional control or stop the aircraft by using the brakes.

Pilots train this all the time in simulators. They should be able to handle it... It is a very common scenario in pilot training in multi engine planes.
