A Russian passenger plane that caught fire as it fell from the sky on Sunday likely suffered engine failure before it crashed, killing all 88 people on board, investigators said. The right engine of the Boeing 737-500 caught fire as it prepared to land in Perm, Russia they said. The plane came down on the outskirts of the city, hitting the ground just a few hundred yards from small wooden houses and apartment buildings. Officials said no one on the ground was killed. Flight 821, operated by an Aeroflot subsidiary, carried 82 passengers, including six children under 10, and six crew members, Aeroflot said. Aeroflot officials said the plane was circling at about 3,600 feet (1,100 meters) in “difficult weather conditions” - including low cloud cover and rain - when it lost contact with ground dispatchers. Witnesses said the plane was on fire as it fell. “I felt an explosion, it threw me off the bed,” a woman in Perm who was not identified told Vesti-24 television. “My neighbors, other witnesses told me that it was burning in the air, it looked like a comet. It hit the ground opposite the next house, trailing like fireworks in the sky.” It crashed around 3:15 A.M. (23:15 GMT Saturday) on the outskirts of Perm, about 750 miles (1,200 kilometers) east of Moscow. The most likely cause was engine failure, Vladimir Markin, a spokesman for the federal prosecutors' Investigative Committee, said in televised comments. The head of the Investigative Committee said examination of the site showed the crash “apparently was connected to technical failure and a fire in the right engine,” the ITAR-Tass news agency reported. “There is much evidence for this,” Alexander Bastrykin was quoted as saying. The plane's flight recorders have been found, and officials said it will take three to four weeks to analyze them. The passenger jet fell on a railroad embankment, damaging a section of the track. Parts of the plane's fuselage reading “Aeroflot” and “Boeing” lay askew on the rails, along with clothing, life preservers and engine parts. Emergency workers in camouflage uniforms picked up human remains and placed them in blue bags. Relatives of passengers said they were asked to provide DNA samples to help in the identification. Part of the Trans-Siberian railway was shut down temporarily as a result of the rail damage, but traffic was restored later in the day, the national railroad company said. Pavel Shevchenko, a 36-year-old Perm resident who lives just 300 yards from the crash site, said he was awoken by an explosion and ran outside. He said a neighbor who saw the crash told him the plane hit the ground at a 30- or 40-degree angle. Shevchenko said he feared his acquaintances or friends could be among the dead. “It's awful. There's just no words to describe it. Perm is a small town, everybody knows everybody else here,” he said. Perm is an industrial center with a population of about 1 million.
