Swap Serials
Explanation
This activity is used to swap serials within a serial structure or between two different serial structures.
If access control is established, you can only swap the serials to which you have access. Establishing access
control is done by assigning a user to an access group which has been defined in basic data. The access groups are
used to extend access to all or selected parts and serials in a structure. When the serials are swapped, the access
groups belonging to the selected serials will be changed. Therefore, swapped serials will receive access from its
new topmost serial's access.
This activity is actually a combination of two removals and two installations. However, it will be carried out
as one integrated activity. All the rules regarding the operational status and configuration that apply to an
installation of a serial pertain to this activity. The following example illustrates the meaning of swapping two
serials within a serial structure. Note: It is possible to swap serials between two different serial
structures as well.
Assume that we have two engines, Engine 01 and Engine 02, that is installed in the same aircraft (they can also
be installed in two different aircrafts). Each engine structure has a pump installed in it and an access group
assigned to it. See the table below:
| Before the serials were swapped |
| Serial structure |
Serial installed in the structure |
Access received from its parent |
| Engine 01 |
PUMP - 03 |
Access Group A |
| Engine 02 |
PUMP - 04 |
Access Group B |
| After the serials were swapped between two
structures |
| Serial structure |
Serial installed in the structure |
Access received from its parent |
| Engine 01 |
PUMP - 04 |
Access Group A |
| Engine 02 |
PUMP - 03 |
Access Group B |
The process of swapping the pumps between the serials is as follows:
-
Pump 03 is removed from Engine 01
-
Pump 04 is removed from Engine 02
-
Pump 03 is installed in Engine 02
-
Pump 04 is installed in Engine 01
When Pump 03 is swapped and installed in Engine 02, the access groups for the pump will be changed. After the
serials are swapped, Pump 03 will receive Access Group B, and Pump 04 will receive Access Group A.
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 swap components 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 values in the Remove or Swap from area appear automatically. These values show the
part/serial information of the serial structure for which the serial will be swapped.
- In the Install or Swap into area, enter the part/serial information of the serial structure the serial
will be swapped into. Enter the ID of the vehicle part you want to swap a serial with. The entered vehicle ID
must be the same as the vehicle ID in the Remove or Swap from area, since you are swapping
components within one structure. When a value in this field is entered, the top part number and the top serial
number appears automatically. Alternatively, you can enter a top part number or the top part serial
directly.
- Enter the structure change position in which the swapped serial is to be installed. Part number, part
revision and the serial number appears automatically.
- Enter the workshop responsible for the swapping of the selected serials. If you want to connect swapping of
the selected serials 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 Run in Batch option if you want
access rights for the swapped serials to be updated through a batch job.
Note: You can also swap serials between two different structures. In this case the values in the
Vehicle ID, Top Part Number, and Top Serial Number fields in the Remove or Swap from
area and Install or Swap into area will differ.
Prerequisites
- Installed serials must exist in both parent structures, and the serials must have the same part number and
revision, or any possible combination of alternates.
System Effects
- The installed serials are both moved from the current structure, and into another.
- 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 Changes.
- 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 a Mandatory type dependency rule is violated when swapping the serials, the operational condition
of the parent serial will be set to Non Operational.
- 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.
- When the serial is installed in a structure, the serial will receive access rights from the parent serial of
the selected structure.
