## Discrepancy

UPON ARRIVAL INTO PANAMA CITY, FLORIDA ON FLIGHT 5466, THE LT AND RT AUTO FEATHER SYSTEM FAILED CAUSING THE CONDENSER BLOWER TO POP. THE SYSTEM WAS LOOKED AT BY THE PANAMA CITY MAINTENANCE. THE PROBLEM WAS THAT THE PRINTED CIRCUIT BOARD WAS BAD. THE CORRECTIVE ACTION WAS THAT THEY REMOVED AND REPLACED THE PRINTED CIRCUIT BOARD. THEY DID A GROUND RUN WHICH WAS NORMAL AND THEY RETURNED THE AIRCRAFT TO SERVICE. THE TEARDOWN REPORT REVEALED THAT THERE WAS NO  DEFECTS FOUND. THE VENDOR TESTED, CLEANED AND RECOATED AS NECESSARY.
