## Discrepancy

THE OUTFLOW VALVE ACTUATOR CLAMP WAS FOUND TO BE LOOSE WHEN YOU PHYSICALLY PUT YOUR HANDS ON THE UNIT. THIS WAS FOUND DURING AN CLOSING OF AFT CABIN WALL PANEL 242AZ NOTICED THAT OUTFLOW VALVE WAS LOOSE.

THE OUTFLOW VALVE WORK CORRECTLY WITH NO INDICATION THAT OUTFLOW VALVE ACTUATOR WAS LOOSE.  NOTE: OUTFLOW VALVE ACTUATOR P/N: 4222363-1002 S/N: 1367 ATTACHED TO OUTFLOW VALVE WITH THE BROKEN CLAMP.
