Narrative:
B-2440 veered off the runway abruptly to the left in an asymmetric thrust condition, eventually stopping in the grass about 2,170 m from the runway threshold there were only minor damage to all four engines and minor cuts to tires.

Findings Related to Probable Causes
After touchdown, when the captain was operating the reversers, because the No. 4 forward thrust lever had been moved forward out of the full retarded position while not being recognized by the flight crew, the No.4 reverse thrust lever was unable to be raised, right after that, the No. 4 forward thrust lever was moved again to the maximum position while not being recognized by the flight crew, generating a greater asymmetric thrust, and as the result, the aircraft rapidly ran off the runway to the left.
