Evaluate and Add LLP Events to Work Scope
Explanation
This activity is used to add LLP events (i.e., the maintenance events 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.
To add LLP events to a work scope, click Assign Events to Work Scope in the Manage
Work Scope Events page. In the Life Limited Parts step of the assistant,
select the required operational parameter from the list of valid values. All possible operational parameters for
all LLP parts in the overhaul object's structure will be displayed in the list. If a minimum release life is
specified for the operational parameter in the baseline, it will be retrieved automatically to the Minimum
Release Life field. Adjust the default value if needed or enter the required minimum remaining days and
click Evaluate Events. The list will be populated with all valid LLP events for the overhaul
object's structure. 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.
Following options can be used to include LLP events to the work scope:
- Manually add events to work scope, by enabling the Include in Work Scope option for the
required LLP event and then clicking Assign Selected Events or clicking
Finish.
- Click Select Overdue Events to add overdue LLP events to the work scope. LLP events with the
Overdue option enabled in the list will be selected automatically. Then click Assign
Selected Events or Finish.
- Click Select Events with Less than Minimum Release Life to add LLP events where the
remaining life is less than the minimum life specified for the visit. LLP events with the Less Than Min
Release Life option enabled in the list will be selected automatically. Then click Assign
Selected Events or Finish.
Prerequisites
- The manufactured date must be defined for the serial.
- Operational logging must be up-to-date. For more information, refer to the activity Report Operational Logging.
- Current stress rating must be updated for the serial.
- The minimum release life should be defined in the Shop Visit Defaults/Minimum Release Life Definition
tab. If this value is not defined it can be entered manually when adding events to the work scope.
- The due calculation for LLP events must be run to define pending events. For more information, refer to the
activity Perform Due Calculation for LLP
Events.
System Effects
- All the LLPs in the overhaul object structure with their rest-life will be listed, and the Less Than Min
Release Life option will be enabled if the LLP is considered for the work scope.
- The LLP events are included in the work scope and will be available for work scope planning. This can be
verified in the Define Work Scope/Work Scope Mx Events tab.
