## Discrepancy

A/C BELT FOUND MELTED AND BROKEN DUE TO A/C COMPRESSOR LOCK UP. HEAT GENERATED ON PULLEY CAUSED REJECTION OF THE PULLEY DUE TO OVERHEATING RESULTING IN CHANGES TO THE METALLURGY.  REPLACED A/C COMPRESSOR, PULLEY AND RECEIVER/DRYER AS REQUIRED IAW APPLICABLE STC INSTRUCTIONS. DURING MAINTENANCE GROUND RUNS, THE NEW A/C COMPRESSOR LOCKED UP WITH THE SAME RESULTS. CURRENTLY WORKING TO REPLACE THE SAME ITEMS AS PREVIOUSLY STATED.
