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.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number SEA07LA145.
