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.
