## Discrepancy

DURING A 100 HR INSP ON ACFT, MSB 1121-109/1 WAS BEING CARRIED OUT AS REQUIRED WHEN IT WAS NOTED THAT THE WASHERS WERE MISSING.  THE MFG WAS CONTACTED AND DETERMINED THAT THIS WAS A NON-CONFORMANCE TO THE TYPE CERTIFICATE.  IT WAS DECIDED THAT THE REMAINDER OF THE FLEET, (11 ACFT) BE INSPECTED TO DETERMINE THE STATUS OF THE ASSY.  THE ENTIRE FLEET WAS INSPECTED AND ALL ACFT WERE FOUND TO BE IN NON-COMPLIANCE AND SUBSEQUENTLY GROUNDED UNTIL THE PARTS ARE INSTALLED.
