## Discrepancy

DURING INSPECTION, THE TUBE ON ENG INLET WHICH CONNECTS TO THE ANTI-ICE TUBE VALVE ASSY WAS FOUND MAKING A 'RATTLING' NOISE WHEN SIDEWAYS LOADS WERE APPLIED.  BORESCOPING REVEALED NO PROBLEM.  DISASSEMBLY OF  INLET FOUND THE 4 BRACKETS WELDED TO THE PICCOLO TUBE ASSY AND RIVETED TO THE INSIDE OF INLET FWD BLKHD CRACKED COMPLETELY THROUGH ON BOTH SIDES OF EACH BRACKET.
