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.
