What was found
(CAN) DURING AN ENGINE REMOVAL THE OIL DRAIN TEE FITTING WAS FOUND TO HAVE THE PICK UP TUBE LOOSE IN THE TEE FITTING. THIS PROBLEM WAS PREVIOUSLY REPORTED IN AN SDR. A MANDATORY SB WAS ISSUED FROM THE MANUFACTURER (MSBZ242L/42A) AND THE FITTINGS WERE REPAIRED AND TESTED IAW THE SB. THIS FITTING WILL BE REPAIRED IAW THE SB AND THEN TESTED IAW THE SB. IF THIS FITTING HAD SEPARATED THE RESULT WOULD HAVE BEEN A RESTRICTION IN THE OIL SYSTEM WITH LOW OIL PRESSURE IN THE ENGINE.
