The NTSB's narrative final · quoted from the NTSB record
The commercial pilot and two passengers had completed a local flight. After a routine touchdown and landing roll, the pilot applied the brakes to initiate a right turn onto a taxiway. The pilot reported that the right brake "grabbed immediately," causing the airplane to ground loop. A postaccident examination and disassembly of the brake system revealed no mechanical anomalies that would have precluded normal operation. The reason for the reported brake malfunction could not be determined.

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 CEN17LA322.
