The NTSB's narrative final · quoted from the NTSB record
The airplane veered off the runway and impacted a runway distance sign during the landing. The airplane was on final approach to the destination airport when the pilot extended the flaps and lost control of the airplane. The airplane slowed and drifted to the left. The pilot added power for a go-around; however, the airplane touched down to the left of the runway centerline approximately 1,000 feet from the approach end of the runway. The pilot reduced engine power, but the airplane continued to the left, exiting the runway surface where it impacted a runway distance marker. The airport manager observed a "moderate amount of rime ice" on the wing leading edges, propeller spinners, and airplane radome immediately after the accident. According to the pilot, the ice was approximately 1/8 inch in thickness. The pilot also reported no mechanical anomalies with the airplane. The FAA's advisory circular regarding icing indicates that even a small amount of ice on the leading edge of the wing can reduce the stall angle of attack and increase stall speed.

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 LAX02LA030.
