What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While in cruise flight at approximately 1,200 feet AGL, the engine failed. The pilot executed a forced landing in a corn field 7 miles southwest of the Crivitz, Wisconsin airport (3D1) causing minor damage to the landing gear and propeller. The engine failed due to a plug extracting itself out and lodging between the rocker arm and valve cover of the nr 2 cylinder. This impeded the operation of the push rod and valve. The pilot is the holder of a student pilot certificate and operated the flight with a passenger onboard.
