3.1 Pitfalls
When compiling an overview of minor and major modifications, there are a few points of attention to
consider, especially when this modification file will be transferred between operators. Completeness of
modification files can be argued.
For modifications that involve additional manual supplements and maintenance requirements, follow-up
requirements are often not embodied in the modification file. As such the accompanying repetitive
maintenance inspections are not part of the maintenance program. Also, supplemental IPC and Maintenance
Manuals are lost. It can be difficult for the next operator to obtain this information.
Other issues are modifications performed outside the control of the operator. Vendor SBs performed during
an overhaul or component repair are indicated on the data plate of the component or in the shop visit report.
Since these modifications are not within the operator’s responsibility, these are not recorded in the
modification overview. Appliance SBs are performed by the operator itself and are therefore listed in the
overview.
