## Discrepancy

AFTER CLOSING MAIN CABIN DOOR, DOOR WOULD NOT LATCH. TRIED CLOSING AGAIN WITH NO CHANGE. RAN CABIN DOOR OPEN ON GROUND QRH AND DOOR LATCHED BUT UNLATCHED IMMEDIATELY. COMPLETED A POWER CYCLE WITH NO CHANGE. DOOR WILL LATCH WHEN MOVING PUSH BUTTON SLIGHTLY TO THE SIDE AND ALSO UNLATCHES DOOR.   TECHS  WERE ABLE TO DUPLICATE THE DISCREPANCY. TECHS FOUND THE PUSH BUTTON SWITCH SC009 FAULTY. TECHS REMOVED AND REPLACED THE PUSH BUTTON SWITCH WITH AN OPERATOR SUPPLIED NEW UNIT PER SB680A-52-10 AND AMM 52-10-16. ALL OPS CHECKS ARE GOOD, NO FURTHER DEFECTS NOTED
