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.
