Check On Condition Modifications
Explanation
Use this activity after the disposition phase of the work scope execution process
has been concluded to generate a list of all applicable On Condition modifications which the user may wish to
address during execution.
On Condition modifications are of three types: On Exposure, On Repair and On
Scrap. On Condition modifications are applicable only when condition is true for
the assigned part for the modification. In other words, if the assigned part is detached/dismounted, or repaired
or scrapped during overhaul, the On Exposure, On Repair or On Scrap modification
respectively is applicable.
On Condition modifications
can have one or more affected parts, which can include the assigned part. On Condition modifications are never mandatory, so
the customer can decide whether or not they should be included in the work
scope. The modification affected serials are defined in the
Modification Details/Assign
Serials tab. Depending on the customer agreement governing the visit, it may be
necessary to secure customer approval before adding the On Condition events to the
work scope.
The user must evaluate On Condition modifications at two main points in the
MRO process. On Exposure modifications need to be considered when setting
maintenance levels during work scope definition. The other types of On Condition
modifications are not relevant at that point. The Check
On Exposure Modifications activity discusses this scenario in more
detail.
During the disassembly and disposition phases of work scope execution the actual parts to be serviced are
identified and then flagged for reuse, repair or scrap.
It is at this point in the work scope execution
process that the Check On Condition Modifications activity is performed.
Having run the report, the user should evaluate the impact of On Exposure
modifications on work scope whenever:
- We encounter a Different Part Found during disassembly for which On
Exposure modifications might be defined.
- We find discrepancies on a part during dispositioning. These discrepancies
could in turn trigger On Repair modifications which affect components of the
part being dispositioned. In this case, the maintenance levels for the work
scope need to be adjusted, and new disassembly, disposition and assembly orders created.
On Exposure modifications may come into play as a result of the additional
disassembly.
- In both of these cases, relevant On Exposure modifications must be added to
the work scope and approved in order for the user to sign off on the modification.
As we mentioned above, On Repair modifications are triggered by the reporting
of discrepancies against the modification assigned part during disposition. A repair
shop order is created for the assigned part to perform the work associated with
fixing the reported discrepancy. This work order can be used to address any
relevant On Repair modifications. The user should evaluate the impact of On
Repair modifications whenever:
- We find discrepancies on a part during dispositioning. These discrepancies
could in turn trigger On Repair modifications which affect components of the
part being dispositioned. In this case, the maintenance levels for the work
scope need to be adjusted, and new disassembly, disposition and assembly orders created.
On Exposure modifications may come into play as a result of the additional
disassembly.
- Relevant On Repair and On Exposure modifications must be added to the work scope and approved in order
for the user to sign off on the modification.
Similarly, On Scrap modifications are triggered when the modification
assigned part is scrapped during disposition.
This will require:
- Reservation of a new serial for which this on-scrap modification has already complied with. This is a manually controlled process.
- If the user cannot reserve of such a serial, the extra operations to perform this modification have to be manually added to the assembly
shop order.
- The On Scrap modification cannot be included in work scope because this new serial number does not exist in the work scope at the time. The
user must manually update VIM that the On Scrap modification
for this serial has been complied with, since the normal sign off process cannot be used in this case.
Prerequisites
- On Condition modifications have been included in the Customer
Maintenance Baseline in the Shop Visit/Visit Defaults/Modification Baseline
tab. If On Condition modifications have not been defined, the report will
still run but will not return any On Condition modifications to be evaluated.
- All disposition shop order lines associated with the work scope have been
approved. The report relies on information that is generated by the approval
process.

Procedure
To print the report from the Maintenance Event Summary window the procedure is:
- Open the Maintenance Event Summary window.
- Query the event summary record for your MRO Shop Visit work order.
- Right-click in the header, then click On Condition Modification -
Report.
- In the Report Print dialog, select the desired options and click OK
to print or Preview to view the report.
To print the report from the
Define Work Scope window the procedure is:
- Open the Define Work Scope window.
- Query your MRO Shop Visit work order.
- Right-click in the header, then click On Condition Modification -
Report.
- In the Report Print dialog, select the desired options and click OK
to print or Preview to view the report.
To print the report from the
Disposition
Shop Order - Complex Assembly Repair window the procedure is:
- Open the
Disposition
Shop Order - Complex Assembly repair window.
- Query the disposition order associated with your MRO Shop work order.
- Right-click in the header, then click On Condition Modification -
Report.
- In the Report Print dialog, select the desired options and click OK
to print or Preview to view the report.
Note that the context of the report is identical regardless of from which
window it is executed - the entire work scope associated with the visit. Running
the report from the
Disposition
Shop Order - Complex Assembly Repair window still
shows relevant On Condition modifications for the entire structure, not just the
component or piece part being dispositioned.
To add events to Reconfigure Work Scope based on the output of the report, the procedure is:
- To add new events to the work scope for the On Condition modifications shown
in the report, navigate to the Maintenance Event Summary/Off
Log tab.
This tab shows the actual parts received during disassembly.
- Select the record for the part for which you wish to add
events tied to an On Condition modification.
- Right-click, then click Reconfigure Work Scope to
launch the Reconfigure Work Scope window.
- Navigate to the Modification tab and in the Baseline Modifications
group select the All Not Complied
option.
- Select the Include In Work Scope check box for those events records
that correspond to the On Condition modification you wish to add to work
scope.
- Save the record.
There are two procedures by which a user can execute new events added to
work scope to address On Condition modifications: modifying an existing repair order or driving changes to maintenance
levels through the interim order and supply order structure. The former scenario
results from a disposition involving discrepancies where we either need or
choose to address On Repair or On Exposure modifications at the level of of the
modification assigned part. The latter results from a disposition involving
discrepancies when we need or choose to address On Repair or On Exposure
modifications on components of the modification assigned part. We will consider
each of these in turn below.
To execute added events by modifying an existing repair order, for an assembly
or a piece part, the procedure is:
- Open the
CAMRO Interim Order Structure window and query the
interim header ID associated with your MRO Shop Visit.
- Navigate to the
Tree Structure/Assembly tab. In the
tree
navigator on the left, select the repair interim order
for the part for which you added On Condition modification events.
- Navigate to the Supply Order tab on the
right. Right-click on the Shop Order supply type record, then click Shop
Order.
- Navigate to the
MRO Shop Order/Material tab and add any
consumable material required to perform your On Condition modification
events.
- Navigate to the
MRO Shop Order/Operation tab and add any
operations required to perform your On Condition modification events. You can
specify operations used to disassemble and assemble into components, repair
one or more components and then re-assemble.
- Navigate to the
MRO Shop Order/Operation Tools tab and add
any tools required to perform your On Condition modification events.
- Proceed with the execution of the of the repair shop order.
To execute events by driving changes to an assembly's maintenance levels
through the interim order and supply order structure, the procedure is:
- Open the Define Work Scope window and navigate to the
Work Scope
Mx Events tab.
- Verify that the new
events you added to work scope for the On Condition modifications are shown.
- Select these new event records, right-click, then click Approve
Maintenance Events.
- Navigate to the
Define Work Scope/Define Work Scope
tab, right-click on the top level part displayed in the tree on the left, then click Expand Descendants.
- To adjust the maintenance level settings for your work scope, right-click on the
Revision node for the top level part, then click Calculate
Suggested Maintenance Level and Apply Baseline. This will wipe out your
current maintenance level settings, reapply the Customer Maintenance Level
baseline and calculate which maintenance levels will expose the affected
parts for your events.
Note that you will be able to see the previous maintenance level settings in
the Define Work Scope/Define Work Scope/Maintenance Level
Summary tab.
- Repeat step 4.
- Make sure the
Assign Maintenance Level tab to the right of the
Define Work Scope tab is active.
- Navigate to the Define Work Scope/Define Work
Scope/Assign Maintenance Level tab. Starting from the bottom lowest
sub-assembly in the product structure and working up, specify the
maintenance level for each part. Use the information displayed in the two
table windows to guide your selection.
Note that you will be able to see your previous maintenance level settings
in the Define Work Scope/Define Work Scope/ Maintenance
Level Summary tab.
The upper table window shows the maintenance levels defined for the selected
sub-assembly. Maintenance levels that expose all component which are
modification affected parts have the Will Expose all Affected Parts
check box selected. The lower
table window displays the component parts of the
selected sub-assembly. Those components which are modification affected
parts have their Mx Event Connected
check box selected.
In the upper table window, right-click on the maintenance level you wish to
select, then click Set Maintenance Level. Note that the lowest level
parts (or leaf parts) in the product structure are not displayed because
these parts do not require a maintenance level to be set. Note also that it is
not necessary to set a maintenance level for a sub-assembly that does not
contain any component parts which have events associated with them.
- Right-click in the header of the Define Shop Visit Work Scope
window, then click Release Work Scope. If you receive a message that
the work scope was not released and errors were created, navigate to the
Define
Work Scope/Define Work Scope/Log Details tab and review
the error messages.
- Repeat steps 6-9 until the the work scope is released without errors.
- Your new maintenance level settings may have exposed previously unexposed
parts which have On Exposure modifications defined. Re-run the On
Condition Modification - Report using the steps specified above.
- Add any On Exposure modifications to the work scope using the steps
specified above.
- Repeat steps 1-12 until no additional On Exposure modifications that you
wish to include in the work scope are called out by the report.
- Right-click in the header of the Define Shop Visit Work Scope
window, then click Interim Order Structure. This will launch the
CAMRO Interim Order Structure window with the record corresponding to your work
scope queried. Verify that any new disassembly, disposition and assembly
orders related to the maintenance level changes for On Condition
modifications you added to the work scope are present.
- Right-click in the header of the
CAMRO
Interim Order Structure window, then click
Release. This will generate the new disassembly, disposition and
assembly supply shop orders corresponding to the new interim orders. Any
disassembly and disposition shop orders that had been previously processed
will be unchanged.
- Proceed with the disassembly and disposition of the newly created
disassembly and disposition shop orders.
- After all the newly created disposition shop order lines have been
approved, navigate to either the Maintenance Event Summary or
Define Work Scope window and follow the instructions specified
above to run the On Condition Modification -
Report.
- Repeat steps 1-17 until there are no additional events from On Condition
modifications to add to your work scope.
