What was found
DURING SCHEDULED LUBRICATION OF THE MAIN ROTOR SWASHPLATE, METAL PARTICLES WERE OBSERVED IN THE GREASE PURGED FROM THE SWASHPLATE. (PLEASE NOTE THAT MFG ALERT SB 430-99-9 REQUIRES THAT GREASE PURGED FROM SWASHPLATE BEARING BE INSPECTED FOR METAL PARTICLES AT EACH LUBRICATION INTERVAL, IF BEARING PN 460-310-450-101 IS INSTALLED. THIS SWASHPLATE HAD BEEN UPDATED, AT MFG, TO THE CONFIGURATION OF TECHNICAL BULLETIN 430-00-25. THIS SWASHPLATE INCORPORATES A PN 430-310-461-101 BEARING, TO WHICH THE RECURRING GREASE INSPECTION REQUIREMENT DOES NOT APPLY.)
