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.
