## Discrepancy

EVACUATED BELLOWS THAT IS USED IN THE FUEL CONTROL, BREECHED 1.2 HOURS AFTER O/H. THE BELLOWS IS NOT OVERHAULED, JUST INSPECTED IAW THE O/H MANUAL.  INSP CRITERIA AT O/H IS HEIGHT CHECK TO DETERMINE POSSIBLE BREACH, VACUUM TEST FOR BREECHING, AND A VISUAL INSP. THE FUEL CONTROL WAS TESTED ON A FLOW BENCH AFTER ASSY AND PASSED AT ALL TEST POINTS. THE BELLOWS IS NOT A TIME LIFE ITEM AND IS STRICTLY CONDITIONAL FOR SERVICEABILITY. MFG HAS REQUIRED REPLACEMENT OF THE BELLOWS AT O/H FOR (1) MODEL ONLY PN 3244777, YET THIS PN BELLOWS IS USED ON SEVERAL OTHER FUEL CONTROL MODELS.
