Remove Part or Serial
Explanation
This activity is used to remove a part or serial from the serial structure.
The removal of a part or serial from the structure is done by removing the reference
to the parent record in the structure. The structural record for the removed
part or serial will still exist in the system, but as a not installed one. When
a part or serial is removed from a serial structure, the structure position
of the removed part or serial will become an empty structure position. Empty
structure positions are used to indicate where expected serials or parts are
missing from the serial structure. Whether a structure position is installed
or not can be identified by the value in the Item Installed field. If
this option is enabled, a serial exists in the structure position and this position
is considered an installed structure position. If the option is not disabled,
a serial does not exist in the structure position and it is considered an
empty structure position.
After removing, the overlying serial in the structure will be set to Out
of Operation and Non Operational if the removed structure record
is part of the minimum configuration. An entry in the replacement history is
generated (one record for the removed part or serial).
If access control is established, you can remove only the parts or serials
to which you have access. Establishing access control is done by assigning a
user to an access group defined in basic data. The access groups will be used
to extend access to all or selected parts and serials in a structure. When a
part or serial is to be removed from a structure, you can specify the access
rights you want to keep for it. You can select to either keep the current access
rights for the part or serial, update the part/serial with the default access
rights, or you can select the access groups you want to keep for the removed
part/serial.
Depending on your workflow, you can perform this activity by clicking the
option Perform Structure Change from one of the following pages.
- Manage Serial Structure
- Serial Initialization
- Perform Structure Change
- Execute Work Task
- Flight Log/Fault
Following is a description of the information that can be entered in each
assistant step.
Step 1 - Structure Change Selection
- Select the remove component option from the structure change section.
Note: If you are using the Perform Structure Change
assistant page, Execute Work Task page or the
Flight Log/Fault tab to perform this activity,
first you have to select the serial for which you want to perform a structure
change. If the structure change is to be performed further down in the structure
of the selected serial, enable the Perform Structure Change for
Sub Serial option and enter the required sub serial details.
Step 2 - Structure Change Details
- The part/serial information for the structure from which the part or
serial is to be removed appears automatically in the Remove or Swap from
section. The structure position from which the part or serial is to be removed
is displayed. If needed, this value can be changed.
- You can enter the location in which the removed (or disconnected) part
or serial is to be placed. If needed, select a new operational condition
for the part or serial that is to be removed from the structure.
- In the Install or Swap into section, enter the part number of
the serial that you want to replace. When you enter a value in this field,
the serial number and installation date appears automatically.
- Enable the Print Serviceability Tag option to order and print
the serviceability tag report for the component being removed. Note:
If the value of the PRNT_SERVICE_TAG_ACS object property in
System Definition/Object Properties is set to
TRUE, this option will be enabled by default. The value of this option
can be changed, if needed.
- Enter the workshop responsible for removing the part or serial. If you
want to connect removal of the part or serial to a maintenance event, enter
a value for the Mx Event Number field.
- Enter the date and time the structure change is to be performed. Enable
the Unscheduled Removal option if this structure change is to be
an unscheduled removal.
- Enable the Keep Current Access option, if the part or serial
to be removed should keep its current access rights. This option is enabled
by default and must be disabled if the part or serial should not retain
its current access rights once the removal is performed. Once this option
is disabled the Default Access Group option is made available.
- Enable the Default Access Group option if the part or serial
to be removed is to be updated with its part access. Once this option is
made available, it will be enabled by default. You need to disable this
option if you want only a selected number of access groups to have access
to the part or serial, once removed.
- Enable the Run in Batch option if you want access rights for
the part or serial being removed to be updated through a batch job.
Prerequisites
- An installed part or serial must exist in a serial structure.
- If you want a location code to be displayed automatically when performing
a structure change on a work order, the location code must be connected
to the workshop the work order is distributed to. This should be done in
the Workshops page.
System Effects
- You will disconnect an item part from its serial structure position
and create a historical record for the disposition (only for serialized
parts).
- If the structure change is performed from a work order, a mismatch record
will be created if the removed serial is not installed in the parent serial.
- The disconnected serial will receive the current access rights by default,
or the specified access groups defined for the serial.
- If the part or serial you remove is part of the minimum configuration
of the structure it is installed in, the operational condition of the parent
serial will be set to Non Operational since the structure becomes
incomplete.
- If the part or serial removed on a work task, a removal transaction
will be created in the structure change log for the work task.
- If a Mandatory type dependency rule is violated when removing
the part or serial, the operational condition of the parent serial will
be set to Non Operational.
- If the part or serial you remove is part of the minimum configuration
of the structure it is installed in, serials that are in direct line between
the top serial and the removed part/serial will be set to Out Of Operation.
- When the part or serial is removed (disconnected) from the structure,
an empty structure position will be created automatically for the affected
position in the serial structure.
- If the structure position is no longer valid, i.e., due to modification
structure impacts, the empty position will be removed from the serial structure.
This cleanup is done through a background job named Update structure
with dummy positions for modification introduced positions.
- If the Print Serviceability Tag option is
enabled, the serviceability tag is printed for the part or serial being
removed. The tag can be included with the part or serial when it is kept
in a facility. Serviceability tag refers to the tag used in the Aviation
industry to clearly identify an uninstalled component or assembly and its
current status. For non-serial parts, the tag will be
printed in the serviceability status you entered, whereas for serial parts
the serviceability status is automatically determined by the system
based the operational status and operational condition of the serial. Therefore,
- If the operational status of the serial is Scrapped, the
serviceability tag is printed with the Scrapped serviceability
status.
- If the operational condition of the serial is Operational,
the serviceability tag is printed with the Serviceable serviceability
status.
- If the operational condition for the serial is Non Operational,
the serviceability tag is printed with the Unserviceable serviceability
status.
