Event Location
Probable Cause
The flight crew’s loss of directional control during landing on an ice- and water-contaminated runway, which resulted in a runway excursion.
Full Narrative
The operator reported that as the airplane entered the vicinity of the destination airport, the pilots prepared for landing. The runway appeared to have been plowed earlier in the day and was wet with a few patches of snow and ice. After a normal touchdown, the pilots deployed the thrust reversers and applied brakes in an effort to gradually decelerate. The airplane began to veer to the right side of the runway and would not respond to the pilots' control inputs. The airplane continued off the runway surface traveling about 70 knots. The main landing gear collapsed and punctured the wings. The airplane incurred major damage to the right wing. The operator reported there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
