Incident Summary
During a slow descent from 5,500 feet to 2,500 feet, the airplane experienced a partial loss of engine power. The pilot increased the throttle position, but the aircraft did not respond as expected. The engine gauges indicated no apparent problems, leaving the pilot without clear indications of the malfunction.
Emergency Actions Taken
The pilot performed standard emergency procedures, sequentially checking the fuel selector valve lever, the electric fuel pump switch, and the fuel mixture control lever. These checks did not restore engine performance, and the engine continued to operate at reduced power.
Forced Landing and Damage
With the aircraft at an altitude too low to reach the nearest airport, the pilot executed a forced landing in an open field. The landing was hard, resulting in the separation of the right main landing gear from the aircraft and the collapse of the nose gear. The extent of other damage is not specified.
