The NTSB's narrative final · quoted from the NTSB record
The pilot reported that, after climbing to about 800 ft above ground level (agl), the engine suddenly stopped producing power. The pilot reported applying full carburetor heat and partial power was restored. The pilot then removed carburetor heat; again, the engine stopped producing power. The pilot applied full carburetor heat, and the engine regained partial power, but not enough to maintain altitude. The pilot made an emergency landing on a dirt road about three miles north of the airfield. During landing the left wing impacted brush and terrain along the road resulting in substantial damage to the left wing. A postaccident examination of the airframe and engine revealed no preaccident mechanical malfunctions or failures that would have precluded normal operation. Weather conditions at the time of the accident were conducive to carburetor icing at cruise power and serious carburetor icing at glide power. Although the pilot reported that he used the carburetor heat, it is likely that ice had already accumulated to the degree that the carburetor heat was insufficient to melt the ice and restore full engine power.

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 ANC25LA005.
