Defining Serial Structures—Extended Exercise

Main Exercise 

Purpose: The purpose of the following exercises is to perform structure changes on your serial structure. You can also update the access rights of the serials which are removed or replaced from a structure. Before commencing with these exercises it would be helpful to read the note given in the following table.  

Important: The serials on which you carry out the structure changes must have received at the least, your access group nMAINTPROVIDER on its template level. This is important as you can only update those serials for which you have been given access. In the following exercises you will see how to handle the access for serials moved in and out of a serial structure.

Perform Structure Change 1 - Installation

Purpose: The purpose of this exercise is to install a serial in your serial structure. You will install a serial part for your Hydraulic Pressure Indicator. Since there is a dependency between the two positions for the hydraulic pressure indicator you will get a warning message. You will then be forced to also install the other position of the hydraulic pressure indicator.

  8. Select the Run In Batch? check box to execute the access rights for serial number nX30900 by a batch job. 
  9. Click Finish.
  10. The serial number nX30900 will automatically receive the access groups defined on its parent serial nX30000. The access group(s) will then be extended to all serials belonging to nX30900.
  11. Repeat for position 106, Part No/Rev/serial No - X32HYD7020, *, nX30901.

Perform Structure Change 2 - Removal 

Purpose: The purpose of this exercise is to remove a serial from the structure. If the airline has decided to stop serving food on the flight, you would need to remove the galley to be able to replace it with some more seats. The serial to be removed should retain its part access. The serviceability tag can be printed for the serial that was removed and accompany it into the facility.

  10. The new serial in the structure (as a result of the swap) will receive the access groups from the serial which it replaced. Likewise, the serial that was replaced will receive the access groups of this new serial. 

Perform Structure Change 4 - Replacement

Purpose: The purpose of this exercise is to replace a serial in your serial structure. Since there is a problem with your turbine in one of the engines you have to replace this with an approved alternate. The access group nMAINTPROVIDER needs to be retained for the serial that is going to be replaced. This structure change will need an approval before you can set the parent template part to operational. The serviceability tag can be printed for the serial that was replaced and accompany it into the facility.

Windows:

  3. In the graphical serial structure navigator, locate the serial X32LEG7004, nX30999 which is to be renamed. Select the row, right-click and then click Serial Structure Information.
  4. Disconnect part X32LNK7008 from the structure. The reason for disconnecting the part is that when the part number of the serial is renamed, part X32LNK7008 will not be a valid part number in the template of the new serial.
  5. Click the General tab and then click the Serial sub tab.
  6. Right-click and then click Rename Serial. The Rename Serial assistant opens.
  7. Enter the new part number X32LEG7005 by modifying the existing value in the field.
  8. Enter valid values for the following: New Part Revision, Manufacturer No, and Manufacturer's Part No fields.
  9. Click Next.
  10. Enter the new maintenance program and the maintenance group in Maintenance Program and Maintenance Group fields respectively. Note: If a valid maintenance program does not exist for the new part revision, it will not be possible to enter values in the Maintenance Program ID and Maintenance Program Revision fields.
  11. In the Template Structure area, observe that the template structure information has changed due to the change of the serial's part number.
  12. Click Next.
  13. Enter the new template part number, template part revision and the structure position for the serials that are connected to the structure.
  14. Click Next.
  15. Use the Rename Serial (Step 4 of 6) - Cancellation of Tasks step to view all running tasks which are connected to the serial that is to be renamed. Note: If running tasks do not exist for the serial, this step of the assistant will not be displayed.
  16. If a task is to be canceled, enter a valid Cancel Task Cause and select the Cancel Task check box.
  17. Click Next.
  18. Click Finish.

To verify the serial rename and install a part in the structure;

  1. Open the Serial Structure Information window and query (F3) for Part Number X747-900 and Serial Number nX30000.
  2. Click the Consist Of tab.
  3. Select the row that holds the serial X32NLG7001, nX30999, right-click, and then click Next Level.
  4. Verify that the serial X32LEG7004, nX30999 has been renamed to X32LEG7005, nX30999.
  5. Next, select the row containing the serial being renamed, right-click and then click Next Level to move down one level in the structure.
  6. Install part X32LNK7009. The reason we install this part is because it belongs to the configuration of the new serial (i.e., the serial after the rename) instead of the part which was disconnected prior to the rename.

Approve Structure Changes

Purpose: The purpose of this exercise is to approve structure changes. In the previous lesson you replaced a turbine with an alternate. Since this part was registered as a qualified interchangeable the replacement will require an approval before the installed alternate is considered usable.
