## Discrepancy

DURING FLIGHT, SELECTED THE VAPOR CYCLE COOLING SYS (VCCS) ON, HOWEVER IT WAS EXTREMELY NOISY AND SHUT IT OFF.   THE COMPRESSOR/CONDENSOR UNIT WAS FOUND TO BE THE CAUSE OF THE NOISE.  MX FOUND THE COMPRESSOR MOTOR BELT COVER DESTROYED, THE BELT OFF OF BOTH PULLEYS AND PIECES OF THE MOTOR PULLEY SPREAD AROUND THE EQUIPMENT BAY.   IT SEEMS THE EDGE OF THE MOTOR PULLEY FAILED ALLOWING THE BELT TO WALK OFF THE PULLEY, EATING ITS WAY THROUGH THE BELT COVER.
