Un avion de tip ATR-72 s-a prabusit luni, in Siberia, cu 43 de persoane la bord. Potrivit celui mai recent bilant anuntat de Ministerul rus pentru Situatii de Urgenta exista cel putin 29 morti si 14 raniti, informeaza AFP.

"Cadavrele a 29 de persoane au fost găsite. Paisprezece răniţi au fost evacuaţi de la locul catastrofei cu elicopterul", a precizat filiala regională a ministerului într-un comunicat.

Un bilant initial informa ca 16 persoane au fost gasite decedate si ca exista 12 supravietuitori.

"Aparatul decolase de pe aeroportul Roscino, de langa Tiumen, si se indrepta spre Surgut (in Siberia). Potrivit datelor preliminare, la bord erau 39 de pasageri si patru membri ai echipajului", a mai precizat responsabilul rus.

Potrivit agentiei de presa ruse, aparatul a disparut de pe radare la putin timp dupa decolare. El s-a prabusit la 40 de kilometri de aeroportul de pe care decolase.

Echipele de salvare au gasit aparatul in flacari.

Avionul apartine companiei locale Utair.

Accidentul a survenit in jurul orei locale 07.50 (01.50 GMT), conform agentiei RIA Novosti, citat de Agerpres.

Degivrarea ? ATR-urile au mai avut astfel de probleme.

Din material rezulta ca anchetatorii se concentreaza pe...2 (sic ) variante : defectiune tehnica a ATR-ului ( la toate accidentele cu aparate straine aceasta a fost principala versiune,infirmata ulterior,n.a. ) si givrarea aripii combinata cu gresala de pilotaj.

"Также источник "Интерфакса" в оперативном штабе по ликвидации последствий авиакатастрофы сообщил, что оба двигателя самолета работали вплоть до гибели машины при столкновении с землей. По крайней мере, к такому выводу пришла техническая комиссия. Этот же источник добавил, что скорее всего, самолет разбился из-за обледенения.

Эту версию, напомним, первыми высказали пользователи авиационного форума Forumavia.ru. Затем, похоже, она обрела сторонников в следственных органах. Руководитель Тюменского следственного отдела на транспорте Сергей Салманов сообщил в эфире телеканала "Россия 24", что может быть несколько причин: "Это ошибка пилотирования, обледенение, погодные условия. Все это будет устанавливаться. Специалисты международного авиационного комитета готовят заключение по техническим характеристикам самого самолета".

Life News цитирует официального представителя Уральского следственного управления на транспорте СК РФ Марину Бубкину: "По предварительной причине, самолет разбился из-за обледенения"

MOSCOW (Reuters) – Failure to de-ice a Russian passenger plane before takeoff was the most likely cause of a crash in Siberia that killed 31 people, federal investigators said on Wednesday.

The UTair ATR 72-200 craft, carrying 43 people, tilted to its right side and then sharply left as it crashed shortly after taking off in near-freezing temperatures in Tyumen, western Siberia, on Monday.

“At the moment, on the basis of the materials received, the investigators consider the failure to conduct a de-icing procedure to be the most probable cause of the air crash,” Russia’s Investigative Committee said on its website.

It said witness statements from those responsible for de-icing the plane and video evidence from the airport’s surveillance systems supported the suspicion.

UTair officials said they would have no comment until the investigation was concluded.

De-icing involves removing snow, ice or frost from a plane’s exterior to prevent a buildup on the wings and tail that could affect its shape or weight, which are crucial during takeoff. The temperature was close to 0 Celsius (32 Fahrenheit) in Tyumen at around the time of takeoff on Monday morning.

The head of Russia’s federal air transport agency Rosaviatsiya, Alexander Neradko, had also said earlier that the plane had not been de-iced properly.

De-icing an ATR 72-200 would cost about 30,000 roubles, Russian media have estimated.

35,000 FLYING HOURS

UTair has suspended flights of ATR 72-200s pending results of a separate investigation by the Interstate Aviation Committee, which looks into air crashes in 12 former Soviet republics.

UTair director Andrei Martirosov said, however, that the decision was made to reassure passengers and that there were no grounds for doubt so far that the plane was in a good technical condition.

UTair said the plane crashed while trying to make an emergency landing.

The federal investigators said the plane had notched up 35,000 flying hours since going into operation in 1992 and had not had a “serious” technical check since 2010.

ATR is an equal partnership between two major European aeronautics players, Alenia Aermacchi, a Finmeccanica (SIFI.MI) company, and EADS (EAD.PA).

The crash was the worst in Russia since a Russian-made Yak-42 slammed into a riverbank near the city of Yaroslavl after takeoff on September 7, 2011, killing 44 people and wiping out the Lokomotiv Yaroslavl ice hockey team.

Russia and the former Soviet republics had one of the world’s worst air-traffic safety records last year, with a total accident rate almost three times the world average, the International Air Transport Association said.

Russia’s transport sector is plagued by deadly accidents blamed on a combination of decrepit infrastructure, human negligence and corruption.
