Evaluate and Add LLP Tasks to Work Scope

Explanation

This activity is used to add LLP tasks (i.e., the tasks which are to be performed on Life Limited Parts) to the work scope. This is the work scope which is created for your overhaul object, e.g., aircraft engine.

Prerequisites

• The manufactured date must be defined for the serial in the Serial Structure Information/Consist Of tab.
• Operational logging must be up-to-date. For more information, refer the activity Report Operational Logging.
• Current stress rating must be updated for the serial in the Serial Structure Information/Additional Serial Info/Life and Cost tab.
• The minimum release life must be defined in the Shop Visit/Visit Defaults/Min Release Life Definition tab.
• The Due Calculation for LLP and Interval Maintenance tasks must be run to define pending tasks. For more information, refer the activity Perform Due Calculation for LLP and Interval Maintenance Tasks.  

System Effects

• All the LLPs in the overhaul object structure with their rest-life will be listed, and the Less Than Min Release Life check box will be selected if the LLP is considered for the work scope.
• The VIM tasks are included in the work scope and will be available for work scope planning.

Procedure

1. Open the Task Summary window and query (F3) for your work order.
2. Click the LLPs tab.
3. In the Operational Parameter list, select All Values and then click Evaluate.
   The table in the tab will be populated with information on all LLPs included in the selected structure. This information includes the calculated remaining life, drop dead date, and less than minimum release life for all operational parameters displayed in the current view.
4. Observe the given information.
5. Next, select a specific operational parameter from the values available in the Operational Parameter list. One of the following occurrences may take place. Choose the option that best suits your requirements:

• If a minimum release life exists for the chosen operational parameter (i.e., a baseline value is defined for the operational parameter), this value is displayed automatically in the Min Release Life field. Click Evaluate.
• If the baseline value is not to be used, change the value in the Min Release Life field to reflect the minimum release life you want. Click Evaluate.
• If a minimum release life does not exist for the chosen operational parameter, you can manually enter a value in the Min Release Life field OR in the Minimum Remaining Days field. Click Evaluate.

Note: When you click Evaluate, the system performs an evaluation of all LLPs in the given structure. If you have specified a minimum release life value, the system only evaluates the LLPs that have the selected operational parameter. However, if a value is specified in the Minimum Remaining Days field instead, the system will evaluate the LLPs for all available operational parameters.

6. Observe the given information.
7. Next, select the Include in Work Scope? check box for the LLP tasks you want included in the work scope.
8. Save the information (F12).
9. Repeat steps 5 to 8 for each operational parameter available in the Operational Parameter list.

The following procedure can be used to make sure that all required LLPs have been included in the work scope. Note: It is recommended that you perform these steps.

10. Right-click anywhere in the header of the Task Summary window, and then click Define Shop Visit Work Scope.
11. The Define Work Scope window opens with details on the work scope for your overhaul object's structure.
12. Click the Work Scope Tasks tab and verify if all LLPs have been included.
