The Southwest Airlines plane that touched down hard at New York's LaGuardia Airport on Monday, skidding and sparking on the runway, landed nose down with the front landing gear contacting the ground first and collapsing, the National Transportation Safety Board said.
The agency on Thursday released what it called “factual information” from the accident of the Boeing 737-700, citing video recordings and other sources.
A spokeswoman for Southwest told the Associated Press the landing was not “in accordance” with operating procedures for the airline.
The NTSB update on Flight 345 was consistent with earlier statements that the landing gear "collapsed rearward and upward into the fuselage, damaging the electronics bay that houses avionics."
The NTSB said that the aircraft’s speed was approximately 133 knots when it pitched down approximately 3 degrees at landing and then skidded to a stop within about 19 seconds.
Investigators were poring over more than 27 hours of recorded data from the entire flight from Nashville to New York as well as two hours of voice recordings from the cockpit.
Of the 150 people aboard the flight, three passengers, the two pilots and three flight attendants were treated and released from the hospital with the minor injuries.
The hard landing, which forced an evacuation via the plane's emergency chutes, shut down parts of the airport overnight as crews worked to remove the aircraft.
