Analysis

After takeoff while climbing to cruise, the plt pulled the throttle to reduce power, but was unable. He then advised ATC & requested landing on the longest rwy. ATC vectored the acft to the west & when it was 3 miles from the rwy, the eng RPM dropped to idle. The plt landed the acft in a field. An investigation revealed the throttle control arm at the fuel controller failed. Vibration then caused the throttle to vibrate to idle. Reportedly, it was worn & had failed due to poor maintenance.
