Incident Overview
A pilot reported that shortly after takeoff, while climbing southbound at 600 feet above ground level, the airplane's engine power suddenly dropped to idle. Despite moving the throttle control back and forth, the pilot was unable to restore engine power.
Forced Landing
The pilot maneuvered the airplane toward a corn field for an emergency landing. During the approach, the airplane stalled above the ground and impacted the field.
Post-Accident Examination
Examination of the throttle control system revealed that the swag ball on the throttle linkage had come off, leaving the throttle control at a low power setting. This mechanical failure prevented the pilot from increasing engine power.
Findings
The investigation determined that the loss of engine power was due to the separation of the swag ball from the throttle linkage, which rendered the throttle control ineffective.
