P/N Control - Proration ProcessA Prorated Part is a part whose life will be based on a prorated standard because it will be used in different service applications. This part must be set up as a prorated part in the P/N Master. A prorated calculation of the life consumed (i.e. sum of the fractions of accrued life) during the part's previous service applications is used to determine the remaining life in its current service application. A part can be used in multiple service applications throughout its life (i.e. installed on different aircraft types/series, or in different assemblies) and therefore it will have different life limits (i.e. P/N Controls) for each of its service applications. These parts are set-up as prorated parts in the P/N Master. The prorated calculation is used only in the planning module and only for a part that is currently in service on an aircraft. It is not used for parts that are in the inventory. The prorated calculation is done automatically by the Trax System using the following formula:
The P/N Control - Proration Process is designed to allow users to visualize the entire procedure for creating a prorated part and following that part throughout the system. ![]() Each step in the process chart is explained in further detail throughout the following documentation. The procedural sections are broken down into the following categories: |
