Top KHL Squad killed in Russian plane crash.

Residual pressure could be a faulty release vavle after the parking brake was released. A blocked valve would hold some pressure. In theory it could accellerate normal to 86 kts with some pressure in the system, as the rotors get hot they expand and then the brake pucks still with same pressure would start to grab more, I'd say a good working theory.

Now we have the real meaning of "residual brake pressure".

Officials have not yet announced the reason for the crash, but have said that all the plane's systems were functioning normally until impact.

Russian media reports said the investigators believe that one of the pilots accidentally activated the wheel brakes during takeoff, while another pilot pulled the plane up to a critical angle in a desperate attempt to get it into the air. The sharp maneuver caused the jet to crash immediately after takeoff.

Probe:Hockey team crash caused by pilot error

MOSCOW—A Russian jet crash that killed 44 people, including an entire professional ice hockey team, was caused by pilots inadvertently putting on the brakes during takeoff, investigators said Wednesday, blaming poor crew training and lax oversight.

The Interstate Aviation Committee said the Sept. 7 crash of the Yak-42 plane near the city of Yaroslavl in central Russia occurred because one of the pilots accidentally activated the brakes during takeoff and then pulled the plane up too sharply in a desperate attempt to take off.

It was one of the worst aviation disasters ever in sports, shocking Russia and the world of hockey, as the dead included 36 players, coaches and staff of the Lokomotiv Yaroslavl hockey team. The only player who survived the crash later died of burns. A flight engineer was the sole survivor.

Alexei Morozov, who led the investigation, said the crew still had enough time to abort the takeoff safely at the moment when they realized that it had gone wrong.

He blamed the plane's owner, Yak-Service, for failing to observe safety standards and adequately train the crew. The company was closed in September by Russia's federal aviation authority following a check that found severe violations.

"The company practically lacked a proper system of flight oversight and controls over air safety," Morozov said.

Morozov said that both pilots had flown another type of plane with a slightly different cockpit layout and apparently had never learned the correct position for their feet on takeoff. He said in the Yak-42, like virtually all other existing Russian and Western planes, a pilot steers the aircraft by pressing the lower part of pedals and activates the brakes by pressing their upper part.

But instead of putting their heels on the cockpit floor as regulations require, the crew left their feet resting on the pedals, inadvertently activating the brakes and slowing the plane down on takeoff. They at first didn't notice they were putting on the brakes, and then made the fatal mistake of failing to abort the takeoff, he said.

Morozov added that a medical condition of the second pilot, and the prohibited medicine he had taken contributed to the disaster. He said the pilot's illness had passed unnoticed during an official medical certification, but had been diagnosed by private doctors whom the pilot had consulted on his own initiative.

The plane was already past half of the long, 3,000-meter (9,900 feet) runway, when the crew tried and failed to lift it. They then weighed on the steering wheel trying to lift the plane and at the same time applied even more pressure on the brakes.

The jet sped past the runway and ran 400 meters (1,320 feet) onto the grass before finally taking off. It went up so sharply that it banked on its wing and crashed on the side of the Volga River, 150 miles (240 kilometers) northeast of Moscow.

The team had been heading to Minsk, Belarus, to play its opening game of the Kontinental Hockey League season.

Among the dead were Lokomotiv coach and National Hockey League veteran Brad McCrimmon, a Canadian; assistant coach Alexander Karpovtsev, one of the first Russians to have his name etched on the Stanley Cup as a member of the New York Rangers; and Pavol Demitra, who played for the St. Louis Blues and the Vancouver Canucks and was the Slovakian national team captain.

Other standouts killed were Czech players Josef Vasicek, Karel Rachunek and Jan Marek, Swedish goalie Stefan Liv, Latvian defenseman Karlis Skrastins and defenseman Ruslan Salei of Belarus.

The crash raised new concerns about Russia's aviation safety and prompted the president to suggest replacing all aging Soviet-era aircraft with Western-made planes.

But industry experts say that recent air disasters have been rooted not simply in planes' age, but in a combination of other factors, including insufficient crew training, crumbling airports, lax government control and widespread neglect of safety in the pursuit of profits.

Mig 29, you must have read the same report that I did except what I also read was that pilots who diverted to other airports or caused dealys in the schedule may loose their bonuses or face other sanctions as the owners attempt to cut costs. The accident investigators surmise the reason the PIC refused to reject the take-off was fear of reprisals from their employer.
Apparently the pilot flying, not realising the brakes were on, yanked the control column to his chest and over rotated in a desperate attempt to get airborne.
Also sited were lack of training and lax oversight on the part of management.
Except that from wat I read, lax oversight on the part of management might be a good thing IF the pilots were properly trained and were more safety concious.
I understand that Russian aviation is not the safest.
On a side note, how many accidents or incidents has been caused by pilots who refuse to reject the take-off? I have heard of a number of them and witnessed a couple, fortunatley none were serious. It is like a deer in the headlights for some.

The aircraft starts taxiing at the 7 minute mark of the animation. I did notice what might have been an attempt to abort take-off, followed by an immediate increase to full power just before impact.

Thanks! Good clip when you understand and read russian

As you hear the crew doing their pre-flight routine, you realize that if they find something wrong with the airplane, they will still be going... Canadian aviation is not perfect, but there are contries like Russia where crews are forced to accept enormous violations and have to exercise poor airmanship on a daily basis just to be able to feed their families. Or be fired. At least here, if you are dissatisfied, in many cases you can leave and find a job in some better place in just a few months. Sadly, it's not like that in Russia.

But not in THAT case, though. They didn't discover anything wrong in their pre-flight routine, but only during the take-off roll after.

Sorry to bump an old thread but I just watched the Mayday episode on this crash and it's crazy. If you haven't seen it it's definitely worth watching.

Cheers,

Yup, ... freaky how they got into that terrible accident on a "beautiful day".
