What was found
DURING A POST INSPECTION CHECK OF AIRCRAFT SYSTEMS, IT WAS DETERMINED THE LEFT ENGINE INLET DEICER WAS INOPERATIVE. A CLOSE INSPECTION OF THE SURFACE OF THE DEICER REVEALED IRREGULAR BULGING AND INDICATORS OF HIGH HEAT. THE DEICER WAS REPLACED AND THE REST OF THE SYSTEM INSPECTED FOR OTHER PROBLEMS. NO OTHER DISCREPANCY WAS FOUND. AGE WAS MORE THAN LIKELY THE CAUSE OF THE CONDITION. BY EXPERIENCE AND CLOSE INSPECTION OF THE SURFACE OF THE DEICER, THE PROJECTED LIFE IS EASILY DETERMINED.
