Departure from LaGuardia was at 2147, November 28 Between LaGuardia and Washington the flight was reported to be uneventful with all of the aircraft's components functioning normally. At Washington, a flight plan was filed with, and approved by, Airway Route Traffic Control It specified Instrument Flight Rules to Dallas, with Wichita Falls, Tex, as the alternate, a cruising altitude of 18,000 feet, and a flight time of 5 hours and 4 minutes The gross height of the aircraft at takeoff was 82,298 pounds, which was 3,577 pounds less than the maximum allowable gross weight of 85,875 pounds, and the disposable load was distributed so that the center of gravity was within prescribed limits. At 0206 the flight requested and received permission to change its flight plan to Visual Flight Rules A posit-,on report was made over Nashville at 16,000 feet at 0254 and a descent was started to 6,000 feet When approaching Nashville, 1 No 1 engine had started backfiring at intervals of about 20 seconds Various corrective measures, including the application of alcohol and carburetor heat, and the richening of fuel mixture, were applied but were not successful and the backfiring continued. The captain and the flight engineer discussed the malfunctioning following which No 1 engine was feathered at a point about 25 miles southwest of Nashville at approximately 0300, however, the feathering was not reported to the company until 0429, where the flight was in the vicinity of Altheimer, Ark, a routine position reporting point about 125 miles beyond Memphis At that time, the crew advised a change of aircraft on arrival at Dallas. When 15 miles northeast of Dallas, at 0536, the flight was given permission to enter the traffic pattern at Love Field, Dallas, with a right-hand turn and instructed to land on Runway 36 The altimeter setting of 29 83 inches and the weather, which included unlimited ceiling, a visibility of 15 miles and a north-northeast wind of 5 mph, were given the flight The captain and the flight engineer conferred regarding returning No 1 engine to service and decided against doing so.

Shortly thereafter the flaps were extended fully, the turn to final placed be aircraft to the left of the runway Accordingly an "S" turn was made to correct the misalignment During this "S" turn the aircraft skidded to Its left, the air speed dropped abruptly and the aircraft settled rapidly. At this point the captain increased power to engines Nos. 2, 3 and 4 in an attempt to maintain control. Control tower operators watching the approach estimated that the aircraft cleared by 75 to 100 feet obstruction lights mounted on 30-foot poles on a power line located 800 feet south of the approach end of the runway. The aircraft continued in a generally northwest direction, across the airport on a heading about 40 degrees to the left of Runway 36, in a tail low attitude. Its air speed continued to fall, its attitude became increasingly nose-high. and a stall developed just prior to striking a hangar and other buildings on the northwest side of the airport. Both pilots and 26 passengers were killed.
