## Discrepancy

DURING TAKEOFF, THE PILOT NOTICED A DROP IN RPM.  FOUND THROTTLE LEVER HAD SLIPPED OUT OF THE FLIGHT GATE GUARD AND THE ACFT WAS NOT CREATING THE NECESSARY RPM TO PRODUCE THE CORRECT POWER.  ON INSPECTION, IT WAS FOUND THAT THE THROTTLE LEVER HAD A GROOVE WORN INTO IT.  THE FLIGHT GATE GUARD WAS ALSO FOUND TO HAVE A DEFECT, IN THAT IT WAS ROUNDED OFF ALLOWING THE THROTTLE LEVER TO SLIP.  A NEW THROTTLE LEVER WILL BE INSTALLED AND THE FLIGHT GATE GUARD WILL BE FILED DOWN TO REMOVE THE ROUNDED EDGE PRIOR TO ANY FURTHER FLIGHT.
