Location: Jaroso, CO Accident Number: CEN25LA310
Date & Time: August 7, 2025, 09:35 Local Registration: N412DJ
Aircraft: Cirrus Design Corp SR22 Injuries: 2 Serious, 1 Minor
Flight Conducted Under: Part 91: General aviation - Instructional

On August 7, 2025 at 0935 mountain daylight time, a Cirrus SR22 airplane, N412DJ, was substantially damaged when it was involved in an accident near Jaroso, Colorado. The pilot receiving instruction and a passenger were seriously injured, and the flight instructor was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight.

The pilot reported that the purpose of the flight was to perform engine lean test procedures. During cruise flight at an altitude of 10,500 ft msl, the pilot reported they had already completed one lean test per the instructions and were starting a second test when the engine suddenly lost power. The instructor attempted to restart the engine by performing the emergency loss of engine power checklist but was unsuccessful in restarting the engine. They chose to activate the Cirrus Airframe Parachute System (CAPS) due to the lack of nearby airports. The CAPS deployed the parachute about 1,500 ft agl, and the pilot reported they were under canopy for about 20 seconds before the airplane landed hard which resulted in substantial damage to the fuselage and both wings.

The airplane was retained for further examination.
