## Discrepancy

FLT 4451 FROM PIT TO CMH. AIRCREW RECEIVED A CHIP DETECTOR LIGHT IN FLIGHT ON THE LT ENGINE. ALL PERIMETERS WERE NORMAL. ON RETURN TO PIT, WITH POWER BROUGHT BACK TO 30 PERCENT,  LIGHT WENT OUT. AIRCREW RETURNED TO PIT SAFELY WITH NO FURTHER INCIDENT. MAINTENANCE LOOKED AT A/C AND FOUND SMALL AMOUNTS OF CARBON, CLEANED CHIP DETECTOR AND SCREEN. GROUND RAN AND OPS CHECKED GOOD
