Narrative:
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.
