Do you know if the various monitored parameters are also used to make fleet-wide predictions (vs. trend monitoring of individual aircraft)?
E.g., perhaps fleet-wide (in aggregate) part X seem to be wearing down (or breaking down) faster than expected, and since part X has a long lead time, a purchasing decision is made sooner.
Have you seen anything like that?
The example 100% happens but I'm not sure about the role of FDR systems in this instance. I do know evaluation of failed components is used to source components with long lead times in anticipation or part changes earlier than necessary as preventative maintenance.
This is a role of a reliability department / TC holder and is usually for airlines with cash!
