Assign Maintenance Level

Explanation

This activity is used to assign, change or reset maintenance levels for an overhaul object (i.e., work order part). Maintenance levels can only be assigned to a sub-assembly and not to a piece part. A piece part refers to a part which does not have components.

The maintenance level to assign, is based on the calculated suggested maintenance level, and modification and LLP (life limited part) maintenance events transferred from IFS/Fleet and Asset Management. For more information on calculating suggested maintenance levels for the work scope, refer the online help file: Calculate Suggested Maintenance Level.

You can view information on the maintenance events and customer approved maintenance baselines which are defined for the selected overhaul object in the Work Scope Mx Events tab, Affected Part Mx Events tab, and the Mx Level Baseline tab.

When you generate a work order part maintenance record, initial maintenance level values are set. These values are derived from the maintenance level baseline defined in Shop Visit Defaults/Maintenance Level Baseline tab. (A work order part maintenance record is generated when clicking on the Calculate Maintenance Levels from Baseline command.) Maintenance levels are assigned in work order part maintenance, and is subsequently used to release a work scope in order to create an interim order structure.

Following can be done as part of this activity:

• Assign a maintenance level or change an assigned maintenance level for a work order part. To do this, select the node in the tree navigator in the Define Work Scope page, click on the Assign Mx Level tab, and click Set Maintenance Level for the required maintenance level. The maintenance level value is assigned to the actual sub-assembly level.
• Remove the assigned maintenance level for a work order part. To do this, click Reset Maintenance Level in the Assign Mx Level tab.
• Remove all assigned maintenance levels for all levels in the structure. To do this, select the top node in the tree navigator and click Reset All (under Calculate Maintenance Levels).

Note: To be able to audit and report to the customer on changes that have been made to maintenance levels applied to a shop visit, it is recommended that the engineering staff enter a comment when a change of a maintenance level is performed. A Part Maintenance Level History record is created to record the fact that a maintenance level change was made against a module. 

The Expose All Affected Parts option is enabled in the Assign Mx Level tab, if all affected parts for a modification or LLP event that is associated to a sub-assembly is included in the maintenance level structure. If you choose a maintenance level record where this option enabled, all affected parts are exposed.

Prerequisites

• A work order must exist for the overhaul object.
• A buildable structure alternative for the work order part needs to be selected.
• Suggested maintenance levels need to be calculated.

System Effects

As a result of this activity, the work scope for the overhaul object is defined and can be released. The assigned maintenance levels can be verified in the Mx Level Summary tab.
