Rob Serial
Explanation
This activity is used to rob a serial from one serial structure and install
it in another.
If access control is established, you can remove only 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
robbed and installed in a serial structure, the new serial, as a result of the
rob, will receive the access groups belonging to the parent serial in the structure.
All the serials below in the structure, will also be updated with these access
groups.
This activity is actually a combination of one removal and one installation.
However, it will be carried out as one integrated activity. All rules regarding
the operational status and configuration that apply to an installation of a
serial, pertain to this activity. If the serial that is to be robbed is of the
minimum configuration type, the operational condition for the parent serial
of the structure will change to Non Operational.
The following
example illustrates the meaning of robbing a serial from a serial structure.
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). Engine 01 has a pump installed in it. Pump 03 is needed to get
Engine 02 functioning as soon as possible. We will now rob the pump from
Engine 01 and install it in Engine 02, the process is as follows;
When a serial is robbed from a structure, the position from which the serial
is removed (robbed) becomes an empty structure position while the position into
which the serial is installed (robbing) becomes an installed structure position.
In the above example assume that Pump 03 is installed in Structure Position
100 of Engine 1. This Pump will be removed and installed in Structure Position
10 of Engine 2. When a rob is performed, Structure Position 100 will become
an empty structure position while Structure Position 10 becomes an installed
structure position. Empty structure positions are used to indicate where expected
serials or part 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.
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 rob 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 vehicle ID, top part number and top serial number appear automatically
in the Install or Swap into section. Enter the structure position
in which the robbed serial is to be installed.
- Enter information for the serial that you want to rob from a structure,
in the Remove or Swap from section. You can enter the ID of the vehicle
part. 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 number directly. Enter the part number
of the serial that is to be removed in the Remove or
Swap from section. When a value in this field is entered,
serial number appears automatically.
- You can enter the workshop responsible for removing and installing
the serial. If you
want to connect robbing of the 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 Run in Batch option if you
want access rights for the robbed serial to be updated through a batch
job
Prerequisites
- An installed serial must exist in the robbed structure, and a free
position must exist in the robbing structure.
System Effects
- The serial is moved from one structure to another.
- If the serial installed is defined as an alternate with the 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 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.
- If the serial you rob 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 robbed serial will be set to Out Of Operation.
- If a Mandatory type dependency rule is violated when this structure
change is performed, the operational condition of the parent serial will
be set to Non Operational.
- An empty structure position is created for the robbed position while
the robbing position becomes an installed structure position.
