CLARENCE, New York: A commuter plane dropped out of the sky without warning and nose-dived into a suburban Buffalo house in a fiery crash that killed all 49 people aboard and one person in the home.
The cause of the disaster was under investigation, but other pilots were overheard around the same time complaining of ice building up on their wings — a hazard that has caused major crashes in the past.
The twin turboprop aircraft — Continental Connection Flight 3407 from Newark, New Jersey — was coming in for a landing when it went down in light snow and fog around 10:20 p.m. Thursday about 8 km short of the Buffalo Niagara International Airport.
Witnesses heard the plane sputtering before it plunged squarely through the roof of the house, its tail section visible through flames shooting at least 15 meters high.
“The whole sky was lit up orange,” said Bob Dworak, who lives about a kilometer away. “All of a sudden, there was a big bang, and the house shook.” Two others in the house escaped with minor injuries.
The plane was carrying a four-member crew and an off-duty pilot. Among the 44 passengers killed was a woman whose husband died in the World Trade Center attacks of Sept. 11, 2001.
Federal investigators found the black box recorders in the plane’s tail that could shed light on what went wrong, but they said the smoldering debris was still too hot to remove bodies. The recorders were on their way to Washington for examination.
No Mayday call came from the pilot before the crash, according to a recording of air traffic control’s radio messages captured by the website LiveATC.net. Neither the controller nor the pilot showed concern that anything was out of the ordinary as the airplane was asked to fly at 2,300 feet (700 meters).
A minute later, the controller tried to contact the plane but heard no response. After a pause, he tried to contact the plane again. Eventually he told an unidentified listener to contact authorities on the ground in the Clarence area.
Erie County Emergency Coordinator David Bissonette said it appeared the plane “dove directly on top of the house.” “It was a direct hit,” Bissonette said. “It’s remarkable that it only took one house. As devastating as that is, it could have wiped out the entire neighborhood.”
The 74-seat Q400 Bombardier aircraft was operated by Colgan Air, based in Manassas, Virginia. Colgan’s parent company, Pinnacle Airlines of Memphis, Tennessee, said the plane was new and had a clean safety record.
The nearly vertical drop of the plane suggests a sudden loss of control, said William Voss, a former official of the Federal Aviation Administration and current president of the Flight Safety Foundation, a nonprofit advocacy group.
Voss suggested that icing or a mechanical failure, such as wing flaps deploying asymmetrically or the two engines putting out different thrust, might have caused the crash.
After the crash, at least two pilots were heard on air traffic control messages saying they had been picking up ice on their wings. “We’ve been getting ice from 20 miles south of the airport,” one said.
Ice on the wings of a plane can alter aerodynamics and interfere with lift and handling. The danger is well known among pilots.
In general, smaller planes like the Dash 8, which uses a system of pneumatic de-icing boots, are more susceptible to icing problems than larger commuter planes that use a system to warm the wings. The boots, a rubber membrane stretched over the surface, are filled with compressed air to crack any ice that builds up.
A similar turboprop jet crash 15 years ago in Indiana was caused by icing. The National Transportation Safety Board sent a team of investigators to Buffalo. The Department of Homeland Security said there was no indication of terrorism.
While residents of the neighborhood were used to planes rumbling overhead, witnesses said it sounded louder than usual, sputtered and made odd noises.
David Luce said he and his wife were working on their computers when they heard the plane come in low. “It didn’t sound normal,” he said. “We heard it for a few seconds, then it stopped, then a couple of seconds later was this tremendous explosion.”
The plane was carrying 2,300 kilograms of fuel and apparently exploded on impact, Erie County Executive Chris Collins said.
It was the first fatal crash of a commercial airliner in the United States since Aug. 27, 2006, when 49 people were killed after a Comair jetliner mistakenly took off from a Lexington, Kentucky, runway that was too short.
