On July 22, 2016, about 1200 central standard time, a Stinson 108-2 single engine airplane, N8019K, registered to a private individual, sustained substantial damage during a forced landing after a loss of engine power near the Dodge Center Airport (TOB), Dodge Center, Minnesota. Of the 3 occupants on board, the private pilot and one passenger sustained minor injuries and one passenger was not injured. The personal cross country flight was being under the provisions of Federal Code of Regulations Part 91. No flight plan was filed and visual meteorological conditions prevailed in the vicinity of the accident. The flight originated from Mankato Municipal Airport (MKT), Mankato, Minnesota about 1130 and was enroute to Oshkosh, Wisconsin.

According to the pilot, the airplane had stopped at MKT for fuel and took off with no problems. After about 30 minutes of flight and cruising at 1,000 AGL, the engine was developing power at a steady 2,350 RPMs when the engine started to lose power to about 2,100 RPMs. The pilot pulled the carburetor heat ON for a few seconds and then pushed it back. The pilot started to look for a place to land and diverted to the Dodge Center Airport. The power remained at 2,100 RPMs for about 10 miles while flying to the airport and then began to lose more power. At this point, the pilot initiated maneuvers to land on a road about 1 mile from Dodge Center. The airplane landed in a field and rolled over. All three occupants exited the airplane through the cabin doors.

Examination of the airplane wreckage by an FAA inspector at the accident site did not reveal any anomalies. The reported weather observation METAR at Dodge Center (TOB) about the time of the accident was:
