## Discrepancy

ON DEPARTURE FROM DTW, THE LT ENGINE ANTI ICE WARNING LIGHT ILLUMINATED. THE FLIGHT RETURNED FOR CORRECTIVE ACTION AND LANDED WITHOUT FURTHER INCIDENT. OHMED THERMISTORS AND FOUND THERMISTOR 3 WOULD INTERMITTENTLY OPEN UP WHILE COOLING. UNUSED THERMISTOR 5 BAD AS WELL. SWITCHED THERMISTOR 3 TO SPARE 4. RAN 30 MINUTES. ALL CHECKS GOOD.
