Maintenance Log pages for Aircraft X (engine 2) fan blades were reviewed by Maintenance Control. During our review; following [the Manual's Operating Procedure] Maintenance Control selected the -8 trackers to be attached to the engine. Aircraft Records Dept are attaching the blades to the individual -9 component not the engine; per the fan map received from the engineering dept. This can be verified using the transaction IES; the next highest assembly displayed is not the engine. If Maintenance Control cannot trust this process; maybe Maintenance Control should be setting up the -8 completely; or eliminating Maintenance Control entirely from determining how to attach the -8 item. Aircraft Records and Maintenance Control are interpreting [the Manual's Operating Procedure] differently. Fan blades should be attached to their respective engine. Maintenance Control does not want to continuously generate [technical inspections] to verify fan blade serial numbers. We need to process the -8 in accordance with [the Manual's Operating Procedure]leaving only one responsible party to determine whether it should be Airframe; engine; gear; or -9 component; this may avoid disassembling the entire fan; to verify a serial number. The fan maps are not reliable for accuracy of the serial number today. [The Manual's Operating Procedure] needs to be clearly followed. Keeping the fan blades attached to their respective engine.
Technician reported disagreement between departments concerning Fan Blade mapping and reporting for tracking purposes.
