NTSB Narrative Summary Released at Completion of Accident
On July 22, 2013 about 1740 edt, N753SW, Boeing 737-700, operated by Southwest Airlines as flight 345, landed hard and sustained a collapsed nose gear on runway 04 at LaGuardia International Airport (LGA), Flushing, New York. Visual meteorological conditions prevailed at the time and an instrument flight plan was filed. Of the 145 passengers and 5 crewmembers, there were 9 minor injuries. The airplane was substantially damaged and there was no fire. The flight was operating under the provisions of 14 Code of Federal Regulations Part 121 as a regularly scheduled passenger flight from Nashville International Airport (BNA), Nashville, Tennessee.
The takeoff, climb, en route and descent phases of flight was normal. The first officer was the pilot flying and the captain was the pilot monitoring. SWA 345 was cleared for the instrument landing system runway 04 approach. According to flight recorder information, the SWA 345 proceeded on the approach until shortly before landing when a transfer of control from the first officer to captain occurred. The airplane touched down on the runway nose first followed by the collapse of the nose gear. The airplane slid about 2,175 feet before it came to rest on the right side of the runway.
The following factual information has been developed:
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. The captain has been with Southwest for almost 13 years and has been a captain for six of those years. The captain has over 12,000 total flight hours, over 7,000 of which are as pilot-in-command. In 737s, the captain has over 7,900 hours, with more than 2,600 as the pilot-in-command. The first officer has been with Southwest for about 18 months. The pilot has about 5,200 total flight hours, with 4,000 of those as pilot-in-command. In 737s, the first officer has about 1,100 hours, none of which are as the pilot-in-command. This was the first trip the flight crew had flown together and it was the second leg of the trip. The first officer had previous operational experience at LGA, including six flights in 2013. The captain reported having flown into LGA twice, including the accident flight, serving as the pilot monitoring for both flights. The en route phase of the flight, which originated in Nashville, was characterized by the flight crew as routine. On approach into LGA, the first officer was the pilot flying and the captain was the pilot monitoring. SWA 345 was cleared for the ILS Runway 4 approach. The weather in the New York area caused the accident flight to enter a holding pattern for about 15 minutes. The crew reported that they saw the airport from about 5-10 miles out and that the airplane was on speed, course and glideslope down to about 200-400 feet. The crew reported that below 1,000 feet, the tailwind was about 11 knots. They also reported that the wind on the runway was a headwind of about 11 knots. SWA 345 proceeded on the approach when at a point below 400 feet, there was an exchange of control of the airplane and the captain became the flying pilot and made the landing. The jetliner touched down on the runway nose first followed by the collapse of the nose gear; the airplane was substantially damaged.
