On March 1, 2019, about 1345 mountain standard time, a Cessna 172N airplane, N6486J, was substantially damaged during a forced landing following a loss of engine power near Melba, Idaho. The flight instructor and student pilot were not injured. The airplane was registered to an individual and operated by Avcenter Inc., under the provisions of Title 14 Code of Federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed, and no flight plan was filed. The local flight departed Nampa Municipal Airport (MAN), Nampa, Idaho about 1310.

The flight instructor reported that they had performed about 12 power-off and power-on stalls, while maintaining an altitude between 4,500 ft and 2,000 ft msl during the maneuvers. While performing the last power-off stall, with the nose of the airplane pitched up, the engine stopped without warning. During the maneuver the throttle lever was in the closed position, and the carburetor heat was in the 'ON' position. The flight instructor pitched the nose of the airplane down and asked the student pilot to restart the engine. The student pilot was unable to rotate the engine using the starter, and the flight instructor verified that the master switch was in the 'ON' position. The flight instructor tried to start the engine himself and was unsuccessful; the engine would not rotate. While looking for a place to land, the flight instructor tried several times to rotate the engine using the starter and was still unsuccessful. The flight instructor performed a forced landing in a field about 12 miles southwest of MAN.

During the landing roll, the right wing impacted the ground and the right wing spar sustained substantial damage.

The initial examination of the airplane at the accident site was performed by the operator's mechanic. The examination revealed that the idle adjustment screw and spring assembly had separated from the carburetor and was found in the lower cowling area. While on site, the flight instructor told the mechanic about the inability to rotate the engine with the starter after the power loss. The airplane was moved to a nearby road and the mechanic was able to rotate the engine via the starter. The airplane was recovered to MAN for further examination.

The examination of the airplane by a Federal Aviation Administration inspector revealed no other anomalies, and the airplane was released back to its owner.
