NTSB Issues Investigative Update into Southwest Flight 345 Accident
The National Transportation Safety Board today released factual information from the July 22 accident involving a Southwest Airlines Boeing 737-700 landing at New York’s LaGuardia Airport. The airplane’s front landing gear collapsed on landing.
• Evidence from video and other sources is consistent with the nose-gear making contact with the runway before the main landing gear.
• The flight data recorder on the airplane recorded 1,000 parameters and contained approximately 27 hours of recorded data, including the entire flight from Nashville to New York.
• The cockpit voice recorder contains a two-hour recording of excellent quality that captures the entire flight from Nashville to New York and the accident landing sequence.
• Flaps were set from 30 to 40 degrees about 56 seconds prior to touchdown.
• Altitude was about 32 feet, airspeed was about 134 knots, and pitch attitude was about 2 degrees nose-up approximately 4 seconds prior touchdown.
• At touchdown, the airspeed was approximately 133 knots and the aircraft was pitched down approximately 3 degrees.
• After touchdown, the aircraft came to a stop within approximately 19 seconds.
• A cockpit voice recorder group will convene tomorrow at NTSB laboratories in Washington to transcribe the relevant portion of the accident flight.
