What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During an instructional flight from kptk, the instructor had demonstrated a few upper air maneuvers to the student pilot. The pilot then descended from 4500 to 2000, to demonstrate a few ground reference maneuvers while enroute back to kptk. When the pilot began to add power to level out, the engine began running rough, vibrating, and the engine was only making 1700 RPM at full power. The instructor took controls, began to trouble shoot, but power continued to decrease below 1600 RPM. The pilot declared an emergency, informed ATC where they were putting the aircraft down, and then began executing an off airfield landing. While on final to the chosen field, the engine stopped completely, and the propeller began windmilling. The aircraft touched down in a field, hit a rock, and came to a stop propped up on its nose. Both pilots exited the aircraft without injuries.
