Incident Overview
Following takeoff, the pilot attempted to reduce engine power by retarding the throttle. The throttle was stiff, and upon applying additional pressure, it suddenly jerked out, thereafter limiting the engine to 1000 RPM. Further manipulation of the throttle did not alter the RPM.
Forced Landing
The pilot was compelled to land on a taxiway. During the landing roll, the airplane struck two parked vehicles.
Examination Findings
Post-incident examination of the airplane revealed that the throttle cable had frozen due to the presence of moisture. The pilot reported that the engine compartment had been preheated to a warm temperature prior to the flight.
Probable Cause
The throttle cable froze due to moisture.
