What was found
(UC2R) THE PILOT REPORTED THA THE PROP GOVEERNOR CONTROL WAS UNRESPONSIVE. THE TECH FOUND THE PROP GOVERNOR ROD END OFF OF THE GOVERNOR ATTACH BALL. THE SPRING SAFETY DEVICE HAD ROTATED AND ALLOWED THE ROD END TO POP OFF OF THE ATTACH BALL. THE ROD END WAY REPLACED AND THE ACFT WAS RETURNED TO SERVICE. WE WOULD RECOMMEND REPLACING THE ROD END PERIODICALLY AND POSSIBLY A BETTER DESIGNED ROD END SAFETY DEVICE.
