## Discrepancy

AFTER TAKEOFF, THE PILOT SAW A TRANSMISSION CHIP LIGHT ILLUMINATE.  HE IMMEDIATELY RETURNED TO BASE AND CALLED THE MECHANIC ON DUTY.  THE MECHANIC ARRIVED TO TROUBLESHOOT.  HE DRAINED AND FLUSHED THE TRANSMISSION, CHANGED THE FILTER, CHECKED AND CLEANED ALL 3 CHIP DETECTORS WITH NO ANOMALIES FOUND, SERVICING THE TRANSMISSION, AND PERFORMED A 20 MINUTE GROUND RUN WITH ASSISTANCE OF THE PILOT.  NO FURTHER DEFECTS NOTED.  THE ACFT WAS THEN PLACED BACK INTO SERVICE.
