Replace Serial
Explanation
This activity is used to replace a serial in a serial structure. Before a
serial can be replaced in a serial structure, observe the following guidelines
for more accurate replacement of the serial.
- A serial with an operational status of Planned For Operation
can be replaced with a serial that has any of the following operational
statuses: Planned For Operation, In Operation, Out Of Operation.
- A serial with an operational status of In Operation or Out
Of Operation can be replaced with a serial that has any of the following
operational statuses: In Operation, Out Of Operation.
- A serial with the operational status Scrapped cannot be used
to replace another serial.
- The serial to connect cannot be locked.
- A serial can only be replaced with the same prime part or with one of
its alternates (position or template alternate). If an alternate is to be
replaced, it can be replaced with the same part number or another alternate,
i.e., an alternate to the part being replaced. Note that when you are performing
a replace, the rules of interchangeability will not apply to serials
that are Planned For Operation, i.e., the serials can be replaced
with any prime parts or any valid alternates defined for the structure position
to be replaced. For more information, refer the activities
Define
Alternate Parts per Position and
Define
Alternate Parts in Template.
If access control is established, you can only replace the 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 serial
is removed from a serial 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 serial, update the serial with the default part access, or select the access
groups you want to keep for the replaced 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 replace serial 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
- Serial information for the structure in which the serial is to be replaced
appears automatically in the Remove or Swap from section. The structure
position in which the serial is to be replaced is displayed. If needed,
this value can be changed.
- You can enter the location in which the disconnected serial (as
a result of the Replace) is to be placed. If needed, select a new operational
condition for the serial that is to be replaced in 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 serial being replaced. 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 replacing the serial. If you want
to connect replacing of a 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 you want the serial
that is to be replaced to keep its current access rights. This option will
be enabled by default. Disable this option if you do not want the replaced
serial to keep its current access. When this option is disabled the Default
Access Groups option will be made available.
- Enable the Default Access Groups option, if you want the replaced
serial to keep its part access. This option will be enabled by default.
Disable this option if you want only a selected number of access groups
to keep the part access when the serial is replaced.
- Enable the Run in Batch option if you want access rights for
the replaced serial to be updated through a batch job.
Prerequisites
- A disconnected serial with the correct status and configuration must
exist. A serial can only be installed in a serial structure whose configuration
(serial structure template) allows it to be installed. This means that a
part number or revision combination not existing (as prime part or alternate)
in a level in the serial structure template cannot be installed in this
level in the serial structure, and vice versa. For more information, refer
to the activity
Define Template Part.
- 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 to which the work order is distributed. This should be done
in the Location Codes per Workshop page.
System Effects
- The disconnected serial is installed in a serial structure, while the
replaced serial is no longer in a serial structure. A replacement historical
record will be created.
- If the serial installed is defined as an alternate with interchangeability
rule Qualified Interchangeable, the alternate must be approved before
the operational condition for the structure can be set to Operational.
For more information, refer to the activity
Approve or Reject Structure
Change.
- If the installed serial is part of the minimum configuration and has
the Non Operational operational condition, the parent serial of the
structure in which it is installed will also receive the Non Operational
operational condition.
- 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.
- If the structure change is performed from a work order, a mismatch record
will be created if the installed serial is installed in another serial.
- The disconnected serial will receive the current access rights by
default, or the specified access groups defined for the serial.
- If the Print Serviceability Tag option is enabled, the serviceability
tag is printed for the serial being replaced. The tag can be included with
the 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. 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.
