Yak-42 crashes in Russia killing hockey team

[MCM]

Evan,

You would like to think that when you noticed the runway was running out you would advance to TOGA, however experience shows us that crew tend to notice quite late in the piece that the runway is running out too quickly. That is probably partially because you are used to using most of the runway on normal takeoffs.

speculation on some Russian media that they decided to reject after v1 due to conflicting traffic, realized they would not be able to stop, changed their minds and decided to try and fly. sounds like bs to me but this is what i am hearing

Sounds plausible enough to me.

...Happened before.

...more than once, Evan.

Wouldn't you advance to TOGA when the runway began to run out?

Yes, but even if you do it can be too late already.

It appears that they didn't even rotate until they hit the lawn.

I'm not sure. It looks like that, but the video is not clear.
It also looks like, when the plane goes over the cammera, the rotation angle is quite large, and still the plane is on the ground. That (if correct, I'm not sure either) would undoubtely mean a too low airspeed.

Yak

This reminds me of a flight I was on in 1995 in a Yak 42 from Batumi in Georgia (former USSR) to the capital Tbilisi. We took off over the Black Sea and cruised for more than 10 minutes at very low altitude over the water, slowly turning back East and finally gaining altitude. The only explanation I could/can think of is that we were too heavy and were burning off fuel to be able to climb. (Might as well not have taken the fuel on board, I hear you thinking).
I would hope the safety situation is better now, 15 years later, but these things keep crashing too often.

The main gear trucks are rotated at the end, so the weight has at least come off them. But I think the fact that this happens well beyond the runway is a sure sign that the airspeed is too low.

I also wonder if the video edit ends the sequence or if the plane hit the camera.

Imagine.. If they published on the web pilots' talks and data from flight recorders, in a day or two all the possible and real reasons would be here in discussions for free...
But not truth is needed, IAC needs desirable acceptable reasons... (

On Sep 12th 2011 the MAK reported, that the on site investigation has been nearly completed. The aircraft, built in 1993, had accumulated 6,500 flying hours, with a design target of 12,000 hours life span. The actual takeoff weight was below maximum takeoff weight. Total fuel on board was 14 tons, 8 tons of which were added in Yaroslavl. An analysis of the fuel is still being carried out. The crew performed a proper flight controls check during takeoff preparation, the elevator moved freely and normally. Weather conditions, including winds, had no influence on the accident sequence. Stabilizer and flaps were properly set for takeoff. All engines were working normally until impact with ground. A single parameter can not be identified as cause from the flight data recorder, all of the system parameters off the flight data recorder are now going to be studied in a special research center. The commission is considering a full scale experiment on the aircraft controls.

Interesting. I have now read those reports, too. Nothing explicitly stated about thrust or speed, but certainly there is an implication that the data presents a normal set of parameters thus far (i.e. there is no one parameter that points to a cause). That brings me back to the possibility of some terrible handiwork on the part of the pilots. Sorry, it's hard not to think along those lines nowadays.

One more version suggested by the officials: the aircraft was accelerating with the parking brake on and the pilots noticed it during the take off run only but it was too late.

I'd be grateful if anyone can find more info on the 2005 event mentioned at 0:55 in this video: http://www.youtube.com/watch?v=8ApFw_Gf7Dg everything I found is in the "show more" video description.

I took a glance, there's hardly any decent info on this accident in English.
Can only give you a link in Russian but it's practically the same you've read in the video description: http://www.logistics.ru/9/6/i77_11081p0.htm
It's said the plane RA-64502 spent about 2hs in air to run out the fuel and then made a successful landing with more than 160 people on board.

Could "pilot unwell" mean that he was still snookered from too much Vodka?

I don't think so.
