THIS WAS DONE TO MINIMIZE THE GROUND TIME FOR THE ACFT. INSPECTION REVEALED EARLY SIGNS OF MIXER DISTRESS. THEREFORE, IT WAS INDUCTED FOR A QUICK TURN WORK SCOPE ON MAY 21ST. ENG WILL BE RETURNED SERVICEABLE TO US ON JUNE 25TH, 2015. COMBUSTOR MIXER DISTRESS ON THE ENG HAS NO INFLIGHT ENG OPERATION AFFECTS. ANALYZES TREND MONITORING OF ALL AIRLINE ENGS FOR EGT PROBE SHIFT SIGNATURES SPECIFIC TO THIS PHENOMENON, WHICH PROVIDES EARLY INDICATION OF DISTRESS. IF A TREND SHIFT THRESHOLD IS ESTABLISHED, ISSUES A CUSTOMER NOTIFICATION REPORT TO PERFORM A BORESCOPE INSPECTION IAW SB 72-0239.
