The NTSB's narrative final · quoted from the NTSB record
The private pilot and passenger were on a local area personal flight in the single-engine airplane. The pilot reported after flying for 20 minutes, he was at 1,500 ft mean sea level when the airplane began to lose engine power and he was unable to maintain altitude. The pilot added full power, full mixture, and carburetor heat, but was still unable to maintain altitude. The pilot subsequently performed a forced landing to a private driveway. A postaccident examination of the wreckage revealed no evidence of preimpact mechanical anomalies that would have prevented normal engine operation. In addition, fuel was plumbed into the engine and the engine ran without anomaly. Although the weather conditions at the time of the accident were conducive to the accumulation of carburetor icing at glide power, the pilot reported that he used carburetor heat, which would have prevented the accumulation of ice.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 ERA21LA304.
