It is normally considered to be cost effective to monitor and control time/cycle sensitive components and larger operators manage to do this with ease and often with an amount of real-time accuracy. Most operators records lag behind slightly - meaning that the records need a small amount of time for the paperwork to catch up with the component when it is removed.
Some operators just don’t get it!
If the operators cannot supply correct TSN/TSO data the component cannot be partially maintained and can only be reset to ‘Zero’ by a complete overhaul. That is the price of inadequate record keeping by an operator.
