THE PLANE WAS LANDED ON A DIRT ROAD; HOWEVER, THERE WAS INSUFFICIENT ROOM TO STOP BEFORE REACHING THE END OF THE ROAD. THE OWNER REPORTED THAT HE SWERVED TO AVOID A DEAD END FENCE. AN INVESTIGATION REVEALED THAT A NUT BACKED OFF OF A THROTTLE LINKAGE BOLT AT THE CARBURETOR ARM. THE BOLT FELL OUT AND THE ENGINE WENT TO IDLE RPM.
