Remove cups with visible cracks and replace with serviceable parts. An alternative to the inspection is replacement of suspected cups with parts which are not in the suspected part no./date code groups. \n\n\tb)\tRecords must be kept to assure traceability of inspections and rework of all assemblies and brake assemblies which were assembled from inventory containing suspected cups. \n\n\tc)\tBrake assemblies installed on aircraft prior to the effective date of this AD do not require removal or inspection. \n\n\tB.F.
