Narrative:On February 25, 2008, at 9:16 p.m. MST, United Airlines flight 267, an Airbus A-320, registration N442UA, departed the right side of runway 19 during landing at Jackson Hole Airport, Jackson, Wyoming. The 119 passengers and 6 crew evacuated the aircraft via the emergency slides. There were no serious injuries during the evacuation and the airplane was not substantially damaged. The flight was operating under the provisions of 14 CFR Part 121 and was enroute from Denver International Airport, Denver, Colorado. Visual meteorological conditions prevailed during the nighttime landing.

The airplane came to rest about 116 feet past the end of the runway and 140 feet to the right of the runway centerline. A heavy skid mark was found on the runway associated with the inboard tire of the left main landing gear. This tire was found deflated and showed wear consistent with a skid. Upon exiting the runway, both engines ingested snow and sustained internal damage.
Examination of the left main landing gear brake system revealed that the inboard and outboard wheel speed tachometer wires were cross-connected. Such a configuration would be likely to cause the antiskid system to use the inboard wheel speed to control the outboard braking, and vice versa. In such a situation, it would be likely that when the inboard tire began to skid, the antiskid system would release the pressure on the outboard brake instead of the inboard brake. Examination of maintenance records indicated that both main landing gear units were replaced on the incident airplane in early February 2008.
