THE LIGHT SINGLE-ENGINED AIRPLANE HAD DESCENDED TO A NEW ALTITUDE. THE PILOT ADVANCED THE THROTTLE WITH THE INTENT OF OBTAINING CRUISE POWER. THE ENGINE DID NOT RESPOND TO THE POWER APPLICATION. IT REMAINED AT THE PREVIOUSLY SET IDLE RPM AND BEGAN GRADUALLY LOOSING THE RPM. THE PILOT CHOSE A FLAT AREA ADJACENT TO A POND FOR THE FORCED LANDING. THE PILOT STATED HE DID NOT TOUCH DOWN ON THE FLAT AREA BECAUSE THE AIRPLANE'S AIRSPEED WAS TOO FAST. THE AIRPLANE TOUCHED DOWN ON THE RIDGE THAT WAS AT THE END OF THE FLAT AREA AND WAS SUBSTANTIALLY DAMAGED. AN ON SCENE INVESTIGATION REVEALED THE THROTTLE ROD END BEARING WAS NOT ATTACHED TO THE THROTTLE RACKET. THE ATTACHING BOLT WAS MISSING. BOTH COMPONENTS WERE COMPLETELY SEPARATEED RATHER THAN ATTACHED.
