Colgan Air Flight 3407 (marketed as Continental Connection Flight 3407 under a codeshare agreement with Continental Connection), was a scheduled passenger flight from Newark, New Jersey, to Buffalo, New York, which crashed on Thursday, February 12, 2009. The aircraft, a Bombardier Q400, entered an aerodynamic stall from which it did not recover, and crashed into a house in Clarence Center, New York, at 10:17 pm EST (03:17 UTC), killing all 49 passengers and crew on board, as well as one person inside the house.The National Transportation Safety Board (NTSB) conducted the accident investigation and published a final report on Tuesday, February 2, 2010, which found the probable cause to be the pilots' inappropriate response to the stall warnings. Flight 3407 is the most recent aviation incident involving a U.S.-based airline that resulted in multiple casualties.Families of the accident victims lobbied the U.S. Congress to enact more stringent regulations for regional carriers, and to improve the scrutiny of safe operating procedures and the working conditions of pilots. The Airline Safety and Federal Aviation Administrative Extension Act of 2010 (Public Law 111–216) required some of these regulation changes.
