At about 11:38 am MT, American Airlines flight 2253, a Boeing 757 inbound from Chicago O'Hare International Airport, ran off the end of runway 19 while landing at Jackson Hole Airport. No injuries were reported among the 181 passengers and crew on board.
The aircraft came to rest in powder snow about 350 feet beyond the runway overrun area. There was no damage to the aircraft.
Instrument Flight Rules (IFR) weather conditions prevailed around the time of the incident with a ceiling of 400 feet,light snow and visibility of 1 mile. Winds were 10 knots from 240 degrees.
The FDR data indicate that the aircraft touched down at approximately 132 knots. At touchdown, the air/ground parameter changes to "ground" for approximately one second and then switches to "air" for approximately ½ second before changing back to "ground" for the remainder of the recording.
The thrust reverser discrete parameters on th FDR indicate that approximately 18 seconds elapsed from the time the reversers began moving until they were fully deployed.
Probable Cause:
The National Transportation Safety Board determines that the probable cause of this incident was a manufacturing defect in a clutch mechanism that prevented the speedbrakes from automatically deploying after touchdown, and the captain's failure to monitor and extend the speedbrakes manually. Also causal was the failure of the thrust reversers to deploy when initially commanded.
Contributing to the incident was the captain's failure to confirm speedbrake extension before announcing their deployment, and his distraction caused by the thrust reversers' failure to initially deploy after landing.
