In fact, early RepairLogic research has found that 44% of repair plans contained one-time use parts that would have been missed using traditional OEM research methods. This primarily stems from how subtly one-time use parts are identified in procedures. Even when one-time use parts are clearly marked, they’re still buried deep within procedures and can easily be missed by those skimming.
To make things more complicated, there is no industry standard for how one-time use parts are marked within procedures: every OEM has their own method. This document is not an all-encompassing document for all one-time use parts markers but can serve as a guide for what to look for with various OEMs.
