## Discrepancy

LOSS OF ENG PWR OCCURRED DURING FLIGHT.  NO ACCIDENT, NO INJURIES.  IT WAS DETERMINED THE THROTTLE CABLE HAD DISCONNECTED FROM ROD END AT THE FUEL CONTROLLER.  JAM NUT APPARENTLY LOOSENED AT THE ROD END.  THROTTLE CABLE DOES NOT HAVE A KEYWAY TO PREVENT TURNING.  PILOT MAY HAVE THOUGHT A VERNIER CONTROL WAS INSTALLED, WHEN IN FACT, HE WAS UNSCREWING THE ROD END AT THE FUEL CONTROL UNIT.
