Cirrus SR22 accident near Tishomingo, Oklahoma, October 24, 2020
On October 24, 2020 at about 5:00 pm local time, a 2008 Cirrus SR22, registered N183V, was substantially damaged in an accident during enroute (descent) near Tishomingo, Oklahoma. It was a personal flight under general aviation rules (Part 91). 4 people had minor injuries. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The pilot’s improper adjustment of the engine mixture control, which resulted in a total loss of engine power. Contributing to the accident was a disconnected oil temperature connector, which was likely damaged during maintenance before the accident flight and provided erratic indications during the flight.

The NTSB's narrative final · quoted from the NTSB record
The private pilot and three passengers departed on a personal flight in visual conditions. As the airplane approached its destination while at an altitude of about 900 ft above ground level, the pilot received cockpit indications of erratic high engine oil temperature. About 5 seconds after the indications began, the pilot moved the throttle to idle power and likely adjusted the fuel-air mixture. About 3 seconds after moving the throttle to idle power, the pilot advanced the throttle to a cruise power setting, but the fuel flow and engine power did not increase. The pilot made additional throttle movements, but the fuel flow and engine power did not correspond to throttle movements most likely because the pilot had adjusted the fuel-air mixture toward a lean setting. Thus, the pilot’s actions in response to the high engine oil indications led to the loss of engine power. Without engine power, the airplane’s airspeed decreased to about 85 knots, and the pilot successfully deployed the airplane’s parachute system. Postaccident examination revealed no anomalies that would have precluded normal engine power. The oil temperature connector and back shell were damaged, with the back shell disconnected from the oil temperature connector. The accident flight was the first after maintenance work during which a crush gasket adjacent to the damaged oil temperature connector was replaced. The oil temperature connector was most likely damaged during this maintenance and resulted in erratic indications of high engine oil temperature during the accident flight.

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 CEN21LA057.
