The NTSB's narrative final · quoted from the NTSB record
The pilot stated that he was turning from the downwind to the base leg of the traffic pattern when the airplane’s engine had a total loss of power. The pilot trimmed the airplane for its best glide speed and maneuvered the airplane toward the runway. However, the airplane impacted the airport’s perimeter fence, which resulted in substantial damage to the right wing. A postaccident examination revealed that the engine air inlet cowling ducting had separated from its attaching material, and the ducting tube slid into the engine air flow control box, blocking the carburetor’s air inlet.

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 ERA12CA198.
