Check On Exposure Modifications
Explanation
Use this activity to generate a list of valid On
Exposure Modifications that are included in a customer modification baseline.
Ideally, this activity should be performed during the work scope definition
process, in order to evaluate which On Exposure Modification(s) should be
included in the work scope as per the defined maintenance level settings.
Note: Depending on the agreement with the customer, you may need to obtain
customer approval before including an On Exposure Modification to the work
scope.
The following conditions need to be fulfilled before an
On Exposure Modification is determined as valid, and the corresponding record is
displayed on the report:
- The part assigned to this modification must be
exposed (i.e., the maintenance level is set).
- Tasks must have been previously defined in the
Task Summary window.
When you initiate the work scope definition process for
your customer and overhaul object, you need to specify maintenance levels that
expose the affected parts for these pre-defined set of tasks. As a result of
this, you may now need to evaluate if the additional On Exposure Modifications
should be included in the work scope. (An On Exposure
Modification can contain a number of affected parts in which the assigned part is included.)
The list of valid On Exposure Modifications is
generated based on the parts in the expected serial structure that will be
exposed by the current maintenance level settings. Since the actual parts to be
serviced are not known until disassembly, this list will include On Exposure
Modifications that are defined for both the prime exposed part and all valid
alternates. It is recommended that you analyze this report, and perform
necessary adjustments on the work scope, before the work scope execution phase
is to begin.
The following actions need to be performed when On
Exposure Modifications are to be included in the work scope:
- The relevant modification records must be defined
for the work scope in the
Task Summary window.
- You may need to adjust current maintenance level
settings for the work scope, so that the parts affected by these On Exposure
Modifications will be exposed.
- When the maintenance level settings are adjusted,
it could expose different parts for which On Exposure Modifications have
been defined. Therefore, the Check On Exposure Modifications activity should
be performed once more.
It is necessary to perform several such cycles till no new On Exposure
Modifications are revealed, after which you can re-release the work scope
and initiate the work scope execution phase.
Prerequisites
- The modification baseline for the customer and
overhaul object, must contain On Exposure Modifications. An On Exposure
Modification is defined by selecting the On Exposure check box for
the relevant baseline modifications in the
Shop Visit/Visit
Defaults/Modification Baseline tab.
- The work scope must have been previously released.
The release of a work scope is required, as it validates that the
maintenance levels you define will expose the affected parts for the initial
set of work scope tasks.

Procedure
Use one of the following options to print the On
Exposure Modification - Report:
Option 01:
- Open the
Task Summary window.
- In the Work Order field, query (F3) for the
work order created for your customer and overhaul object.
- Right-click anywhere in the header, and then click
On Exposure Modification - Report. The
Print Report
dialog box opens.
- Click Preview to verify the information
shown on the On Exposure Modification - Report before you continue.
- Print the required report.
Option 02:
- Open the Define Work Scope
window.
- In the Work Order No field, query (F3) for
the work order associated with the required work scope.
- Right-click anywhere in the header, and then click
On Exposure Modification - Report. The
Print Report dialog
box opens.
- Click Preview to verify the information
shown on the On Exposure Modification - Report before you continue.
- Print the required report.
Use the following procedure to add new On Exposure
Modification tasks to the work scope:
- Open the
Task Summary window.
- In the Work Order field, query (F3) for the
work order created for your customer and overhaul object.
- Click the
Modification tab, and
select the All Not Complied option in the Baseline Modifications
area. All baseline modifications that have not been complied with thus far
will be displayed on the available table.
- Select the Include In Work Scope? check box
for the On Exposure Modification(s) you want to add to the work scope.
- Save your changes (F12).
- Right-click anywhere in the header, and then click
Define Shop Visit Work Scope. The
Define Work Scope
window opens with details of the work scope associated with your work order.
- In order to proceed with the activity, you need to
approve the tasks you have added to the work scope. To do this, right-click
anywhere in the header, and then click Approve All Tasks. An
information message appears requesting approval of the task, click OK.
- Click the
Define Work Scope tab. The
graphical object structure shown on this tab can be expanded to show all
components for your overhaul object structure. Select the top part in the
structure, right-click, and then click, Expand Descendants.
- Next, right-click on the revision node for this
top part, and then click Calculate Suggested Maintenance Level and Apply
Baseline. An information message appears requesting approval of the
task, click OK. As a result, the part records in the
Assign
Maintenance Level sub tab is updated with the calculated assigned
maintenance level.
- Starting from the bottom lowest sub-assembly in
the product structure and working up, specify the maintenance level for each
part.
Note: You can make use of the
information displayed in the tables of this tab to guide your selection:
In the upper table, the maintenance levels
defined for the selected sub-assembly is displayed. If the
Expose All Affected Parts check box is selected, the defined
maintenance level will expose all components that are considered parts
affected by a
modification or LLP (life limited part).
In the lower table, the component parts for the selected sub-assembly is
displayed. If the Task Connected check box is selected, the
corresponding component part is a modification affected part.
The parts in the lowest levels of the product
structure (also called leaf parts) will not be displayed, as these parts
do not require maintenance level settings.
|
In the upper table, select the row that contains
the required maintenance level, right-click, and then click Set
Maintenance Level. You are not required to set maintenance levels for
sub-assemblies, if these sub-assemblies do not contain any component parts
which are considered modification affected parts.
- Right-click anywhere in the header of the
Define Work Scope window, and then click Release Work
Scope. An information message appears requesting approval of the task,
click OK.
If an error message is displayed, stating that the work scope could not be
released and errors were created, click the Define Work
Scope/Define Work Scope/Log Details sub tab to view the generated
records. If such an occurrence arises, you need to set maintenance levels
for the product structure once more. Note that this process may need to be
performed a number of times until you are able to release the work scope.
- To ensure that you have not missed including any
On Exposure Modification to the work scope, repeat
Option 01 or Option 02.
