## Discrepancy

DURING CLIMB OUT OF HILO, I NOTICED THE CABIN FELT WARMER THAN USUAL. I CONFIRMED THE ENVIRONMENTAL SWITCHES WERE IN THE APPROPRIATE POSITION, THEN CHECKED THE LOAD METERS WHICH WERE INDICATING THE A/C COMPRESSOR MOTOR WAS NOT OPERATING. I TOGGLED THE ENVIRONMENTAL CONTROLS, HOWEVER WAS UNABLE TO CORRECT THE FAULT. AFTER CONFIRMING THE A/C WAS INOP I SWITCHED THE ENVIRONMENTAL CONTROL TO THE OFF POSITION AND ONLY UTILIZED THE ENVIRONMENTAL BLOWER. REPLACED AC DRIVE MOTOR (INTERNALLY SHORTED). GROUND OPERATIONAL CHECK SATISFACTORY
