The forecast for Tucumcari, the alternate airport, indicated clear weather until 0500, followed by an overcast, with a ceiling of 800 feet and surface winds from the northeast at 15 miles per hour. The flight was routine and on reaching Acomita, New Mexico, at 0755, reported that it was 500 on top at 12,000 feet and was estimating Albuquerque at 0811. Following this report the flight asked to change its flight plan to Tucumcari with Amarillo, Texas, the alternate, and requested the latest Tucumcari weather which was: 0728, overcast, 1500 feet, visibility 20 miles, wind northeast 20 mph; Amarillo, 0728, broken clouds 1700 feet, overcast at 3500 feet, visibility 8 miles, wind north-northeast, 17 mph. The flight passed over Albuquerque under broken clouds in the clear at 12,000 feet NSL at 0813, whereupon the following clearance was given: “ARTC (Air Route Traffic Control) Clears CAM 5763 to the Tucumcari Airport via Green Airway No. 4, to maintain 500 on top while in the control area.” This clearance was acknowledged. At 0831, the flight reported being over Anton Chico, New Mexico, at 13,000 feet, estimating Tucumcari at 0852. At this time the 0828 Tucumcari weather was given the flight as; coiling estimated 1,000 feet, overcast, visibility 3 miles, snow and fog. At approximately 0845, Tucumcari radio gave 5763 the following clearance: “ARTC clears 5763 to descend to 8,000 feet on the south course of Tucumcari range, maintain 11,000 feet until 2 minutes south, descend outbound, maintain 8,000, report leaving 9,000.” The following clearance was transmitted to the flight by Tucumcari radio at 0851: “ARTC clears 5763 to approach Tucumcari Airport en reaching 8,000 feet.” The flight next reported being over the Tucumcari range station at 0852, at 11,000 feet, descending to 8,000 feet, and at 0901 reported that it was at 9,000 feet outbound on the south leg of the Tucumcari range. At this time the special 0852 Tucumcari weather report was given the flight: “Ceiling 800 feet, overcast, visibility one mile, light snow and fog, wind north 20 miles per hour with strong gusts.” The reported surface visibility in this official weather report was loss than the CAA and company minimums of 11/2 miles for the Tucumcari Airport. At 0907 5763 was given the following clearance: “ARTC clears 5763 to make standard instrument approach.” The Amarillo weather was then given as: coiling estimated 1,000 feet, broken clouds, overcast 2,000 feet; visibility 5 miles, light snow and fog. The flight was asked if it wished to proceed to Amarillo and it replied that it had to land at Tucumcari. The flight continued its descent and at 0909 was advised by Tucumcari radio that the Tucumcari weather was then ceiling 800 feet, overcast, visibility 1/2 miles, light snow and fog, wind north 20 miles per hour. Two minutes later, at 0911, the flight reported it was outbound on the west leg at 8,000 feet, descending to 6,000 feet. Tucumcari radio again gave the flight the weather which had been given it at 0908. One minute after this transmission Tucumcari radio gave the flight the wind direction which was then north-northwest, variable to north-northeast, at 16 miles per hour, and advised that Runway 30 was the runway in use. 5763 immediately requested the bearing of this runway and this was corrected to 03, which was acknowledged by the flight. At 0915 5763 reported that it was at 6,000 feet and inbound on the west leg of the Tucumcari range. Immediately following this report, at 0916, Tucumcari radio asked the flight if it wanted ARTC to recommend an alternate airport closer than Amarillo. The flight acknowledged this and advised it would have to land at Tucumcari but asked where the alternate would be. The pilot was advised to stand by and, according to the communicator on duty, the aircraft was then seen to cross the field in a northwesterly direction at very low altitude. The pilot was quickly advised to pull up and answered that he was doing so. At 0925, the flight advised it was landing downwind. This was the last report received from the flight. After several passes over the airport at altitudes varying from 500 feet to as low as 50 feet, the aircraft crashed near the northeast end of Runway 21 at approximately 0929. A flash fire which occurred immediately after impact quickly subsided. Ten passengers were injured and another one was killed. The aircraft was destroyed.
