A Yak Service Yakovlev Yak-42, registration RA-42434 performing a charter flight from Yaroslavl (Russia) to Minsk (Belarus) with 37 passengers (the Lokomotiv Yaroslav Hockey Team) and 8 crew, could not climb out after takeoff from Yaroslavl's Tunoshna Airport at approx. 15:50L (11:50Z). The airplane impacted an antenna outside the airport perimeter, impacted ground and came to rest about 1000 meters from the airport broken up in two major parts, the tail section at the bank of Volga River and the fuselage in the river. 43 bodies have been recovered, two occupants have been taken to hospitals with critical injuries, one of the two survivors died on Sep 12th in hospital care.

The Lokomotiv Yaroslavl Club reported, all of the A-Team were on board of the aircraft. The Ice Hockey Team was departing to play this season's opening match against Dynamo Minsk.

According to Yaroslavl hospital the two people delivered to the hospital are a flight engineer and the Russian player Alexander Galimov. Alexander Galimov is still (Sep 7th 20:00Z) in critical condition with burns of more than 80% of skin and burns to the respiratory tract in addition to internal injuries caused by impact forces. The status of the flight engineer was upgraded to satisfactory late evening (local). The hospital denied news reports that Alexander Galimov had died in hospital.

Both survivors were flown to Moscow for treatment of the burns. While the flight engineer is on the way to recovery, the burns of Alexander Galimov proved "incompatible with life". The research hospital confirmed he died in the morning of Sep 12th.

Russia's Emergency Ministry (MCHS) Yaroslavl office reports 37 passengers and 8 crew were on board, 26 bodies have been recovered from the river, 2 people have been taken to hospitals. By Sep 8th 09:00L the MCHS reported that 43 bodies were recovered in 30 dives, only two occupants survived and are in hospital care.

Rosaviatsia reported 34 occupants were killed, 3 occupants survived. The aircraft failed to climb to safe altitude, impacted an antenna outside the airport perimeter and fell to ground breaking up.

Rostransnador (Russia's Transport Ministry) pledged priority action to determine the circumstances of the crash. All Yakovlev Yak-42, 57 of them in Russia, remain grounded until then.

On Sep 9th Rostransnador reported, the aircraft had been refueled at Tunoshna Airport uplifting 7 tons of fuel. The aircraft subsequently began its takeoff roll from intersection with taxiway 5 (about 2850 meters of takeoff distance available).

Tunoshna Airport's Air Traffic Controllers reported they saw the crash from their control room. The aircraft had reached a few tens of meters of height, then suddenly rolled left and impacted ground.

A surveillance camera showed that the aircraft took off with flaps in takeoff configuration, however rotated past the end of the runway and became airborne just before the localizer antenna.

Policemen observing the accident reported the aircraft barely got airborne, impacted the localizer antenna, immediately thereafter rolled and turned left and impacted ground.

Aerial images show the first debris off the aircraft began just past the localizer antenna and continued, getting more and more intense, towards the final position.

Russia's MAK reported an investigation has been opened. The MAK initially provided the tail number as RA-42433, which is another Yak-42 belonging to Tatarstan Air, but later changed to RA-42434. Investigators have arrived in Yaroslavl and are surveying the accident area collecting evidence. Late Sep 8th the black boxes were recovered from the wreckage.

On Sep 9th 2011 the MAK reported first data off the flight data recorder confirmed the flaps were set at takeoff configuration of 20 degrees, the stabilizer was set at 8.7 degrees nose up. The engines worked until the moment of collision with obstacles.

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.

Radar data confirm RA-42434 had positioned from Moscow Vnukovo to Yaroslavl as flight AKY-9634 arriving at approximately 14:10L (10:10Z).

According to ATDB Yak Air Service operates two Yak-42s: RA-42434 and RA-42387.

No Metars are available, the local weatherstation reported visibility above 50km (27nm), partly cloudy, winds from the north at 14kph (7.5 knots), temperature 17 degrees C, dew point 7 degrees C, humidity 40%, rapidly dropping QNH (1014 hPa at 10:00L, 1011 hPa at 13:00L and 1008 hPa at 16:00L).

A voi i commenti

Il commento che posso fare è che l'intervento dei freni per errata manovra del pilota ha rallentato l'accelerazione del velivolo e ha contrastato la rotazione del muso.
Quando finalmente le ruote del carrello principale si sono staccate da terra i motori stavano erogando la spinta massima e l'equilibratore era a fondo corsa a cabrare per cui il muso, che nel frattempo era riuscito comunque a ruotare dando all'aereo un assetto a cabrare di diversi gradi, libero dal momento contrastante dato dai freni, ha assunto ancora di più tale assetto, portando l'angolo d'attacco a un valore per il quale è stato inevitabile lo stallo.
Per il resto ci sono state notevoli mancanze dovute a superficialità nei controlli da parte degli enti preposti e dalla compagnia.
