Colgan Air Flight 3407, marketed as Continental Connection under a codeshare agreement with Continental Airlines, crashed on February 12, 2009, at 10:17 p.m. EST, into a house in Clarence Center, New York, after experiencing an aerodynamic stall. All 49 people on board were killed, along with one person in the house. It was a Bombardier Dash-8 Q400, registration number N200WQ, on a scheduled regional airline flight from Newark, New Jersey to Buffalo, New York. The accident triggered a wave of inquiries over the operations of regional airlines in the United States; it was the first fatal accident of a commercial airliner in the U.S. since the August 2006 crash of Comair Flight 191. It remains the most recent fatal crash of a U.S.-based commercial airline. The accident was investigated by the National Transportation Safety Board (NTSB), with a final report issued on February 2, 2010. The NTSB determined that the accident was caused by the pilots' inability to respond properly to the stall warnings. Families of the accident's victims lobbied the U.S. Congress to enact more stringent regulations for regional carriers, and apply greater scrutiny to safe operating procedures and the working conditions of pilots. The Airline Safety and Federal Aviation Administrative Extension Act of 2010 required some of these regulation changes.
