## Discrepancy

(CAN) AFTER DRAINING ENGINE OIL  DURING A 100 HOUR INSPECTION, THE VALVE WAS CLOSED. UPON CLOSING THE VALVE, IT CAME APART. NO ABNORMAL AMOUNT OF FORCE WAS APPLIED. THE VALVE IS SPRING LOADED CLOSED. IF THIS WERE TO HAPPEN IN FLIGHT ALL OIL COULDBE LOST AT A RAPID RATE. THE VALVE WAS REPLACED WITH A DIFFERENT STYLE OF UNIT. ALL THESE VALVES SHOULD BE REMOVED FROM SERVICE.
