A320 Captain reported a flight cancellation was caused by improper maintenance tracking of a required fan blade inspection.

Narrative

We [were] operating flight Aircraft X ZZZ-ZZZ1. After door closure but before push back we get an ACARS message to contact Maintenance Control.I called on my phone and talked with Name; he informed me that there might be a problem with our aircraft maintenance logbook and an inspection that might be due. My first call was at XA:08 local time. Name informed me to hold the flight at the gate while they [were] researching the timing of the write up on log page XXXXXXX; of Aircraft X; there was supposed to be an inspection of a fan blade made within a certain time frame.We had the jet way pulled back to the aircraft and open the main cabin door. I informed passengers of the situation and that we [were] waiting on further information from our Maintenance Control in ZZZ. We communicated our situation with the Station Operations and Dispatch.At XA:48 local time I called Maintenance Control again; at this time I was informed that the aircraft was grounded because an inspection was due.I informed our passengers of the situation and asked them to deplane. The flight had been canceled.If the aircraft maintenance logbook had a block to where the time of the write up could be logged we as pilots could help track the timing of required instructions. The current logbook is of no use to pilots. If we know when a write up was done we could refer to our MEL/CDL (Configuration Deviation List) and see when an inspection or a resolution would need to be done.
