The NTSB's narrative final · quoted from the NTSB record

The aircraft's touchdown and rollout were uneventful until the pilot activated/engaged the nosewheel steering system to make a left turn off the runway. At that time, the aircraft suddenly veered to the right and departed the side of the runway. After the aircraft departed the runway, it encountered a four-foot-high snow bank, which resulted in substantial damage to the airframe. After the accident, the nosewheel steering system was examined and tested, and it was determined that the nosewheel was making uncommanded turns when the system was activated. The source of the system malfunction that lead to the uncommanded turns could not be positively identified.
