Defining Serial Structures—Exercises

Main Exercise

Purpose: The purpose of these exercises is to create your own serial structures using different methods.

Create Serial Structure - 1

Purpose: The purpose of this lesson is to learn how to serialize a template structure for the Landing Gear. 

Windows:
Serial Structures

Steps: To complete this exercise, perform the following steps.

  1. Open the Serial Structures window.
  2. Create a new record (F5) and specify the part number nX32NLG7001 and part revision *.
  3. Enter Serial Number nX31000.
  4. Enter Maintenance Group nAC.
  5. Enter your Workshop Code nLAX-C.

  9. Save the information (F12).
  10. You are now ready to copy the structure. Right-click and click Import Template Structure (do not select the Generate Serial Numbers check box).
  11. You get a message of how many parts that were copied.
  12. Right-click, and then click Serial Structure Information. Click the Consist Of tab.
  13. Enter required information on each serial:
        Serial Number nX31999 ("9" means any digit)
        Maintenance Group nAC (eventually *)
        Workshop Code nLAX-C
        Manufacturer Number and Manufacturer Part Number
        Manufactured Date (this value is required when the part is a life-limited part)
        Ownership Company Owned
  14. Right-click and click Next Level and Previous Level functions to get to the other serials. Enter information described in step 13 for the serials.
  15. Save the record (F12).
  16. Click the Multilevel tab and check that all data are registered correctly.

Create Serial Structure - 2

Purpose: The purpose of this lesson is to make another Landing Gear serial structure. This lesson introduces you to an alternative way of generating serials by copying an existing serial structure. This will include additional information about Alternates etc. In this exercises you will also apply automatic serial number generation (temporary S/N) before entering the actual serial numbers.

  13. In the Serial Structure Information window click the Consists Of tab and verify that (temporary) serial numbers with a format of NO-9999 have been generated.

Rename Serials

Purpose: The purpose of this exercise is to modify serial numbers in a newly copied structure for the nX32000 Nose Landing gear, you will enter serial number on sub-structure parts to be in the nX32999 series.

Prerequisite: The previous lessons must be completed.

Windows:
Serial Structure Information

Steps:  To complete this exercise, perform the following steps.

  1. Open the Serial Structure Information window.
  2. Query (F3) for your parts of interest: Part Number nX32% and Serial Number NO%. Important: Verify that you have the correct serial records.
  3. Select one of your serial records.
  4. Right-click on the lower section of the General tab, and then click Rename Serial. 
  5. Use the Rename Serial wizard to modify the serial number of the Nose Landing Gear to be in the nX32999 series ("9" means any digit).
  6. Reset the operational status to be In Operation. (You may have to change the operational condition to Non Operational first, and then change the operational condition to Operational again so you can select the Set serial to be In Operation status check box within the Set Serial to be Operational dialog box.) 
  7. Repeat steps 3 through 7 for each serial number.
  8. When finished, select the Nose Landing Gear (nX32000), go to Serial Structure Information and examine the serial numbers in the Multilevel tab.

Create Serial Structure - 3

Purpose: The purpose of this lesson is to make a serial structure of your aircraft (vehicle level). You will do everything in the Serial Structure Information window.

Windows:
Serial Structure Information

Steps: To complete this exercise, perform the following steps.

  1. Open the Serial Structure Information window.
  2. Create a new record, specifying the nX747-900 part number, and the * part revision.
  3. Specify Serial Number nX30000 and Vehicle ID nN.
  4. The Template Part No and Structure Position fields are automatically populated with the template part number, revision and structure position of the serial. 
  5. Specify Owner Org HQn (create it if it does not exist).
  6. Specify the following:
        MaintGroup - *
        Workshop Code - nLAX-C
        Manufacturer ID - V81205
        Manu Part - B747-900
        Location - LAX
        Ownership - Company Owned.
  7. Save the record (F12).
  8. Right-click and then click Import Template Structure do not select the Generate Serial Numbers check box.
  9. Click the Consist Of tab.
  10. Specify Serial Number nX30999 for all the serials of your aircraft except the serials for the hydraulic pressure indicator ("9" means any digit). Also specify;
        Maint Group - nAC
        Workshop Code - nLAX-C
        Manufacturer No and Manufacturer Part No
        Manufactured Date (this value is required when the part is a life limited part)
        Ownership - Company Owned
  11. For each serial part. Right-click and click Next Level and Previous Level to navigate in the structure.
  12. Save the record (F12). 
  13. For this serial structure it is not needed to define the two positions for the hydraulic pressure indicator (not part of the minimum configuration).
  14. Delete the rows by selecting the row (one by one) right-click, point to Structure Changes, and then click Remove Part or Serial.
  15. Enter your location code.
  16. Enter your workshop code.
  17. Click Finish.
  18. Open the Multilevel tab to verify that the structure is correct and all serials have a serial number. 
  19. If a printer is available, make a Serial Structure-Multilevel printout of this serial structure. 

Define Average Utilization for a Serial

Purpose: The purpose of this exercise is to define an average utilization for the serial. For fleets with regular utilization, defining an average utilization value on part level will in most cases work fine. However, for fleets where utilization is more irregular, i.e., an aircraft is used heavily in a period but is then not used at all in other periods, the average utilization needs to be defined per serial.

Prerequisite: The previous lessons must be completed.

Windows:
Serial Structure Information

Steps: To complete this exercise, perform the following steps.

  1. Open the Serial Structure Information window.
  2. Query (F3) for your serial number nX31000.
  3. Click the Additional Serial Info tab and then click the Average Utilization sub tab.
  4. Create a new record (F5).
  5. In the Operational Parameter field, enter FHR.
  6. In the Average Value field, enter value 200.
  7. Save the record (F12).
  8. If an operational budget or historical operational loggings exist for your serial, you can right-click on the record and then click Calculate Average Value. The Calculate Average Value dialog box opens.
  9. Select Planned Average to retrieve the operational budget value defined for the serial or select Historical Average to calculate the average value based on the 12 months of operational loggings.
  10. Click OK. The average value is calculated and displayed in the Average Value field.
  11. Repeat steps 4 through 7 to enter several operational parameters for the serial number.

Set a Structure In Operation

Purpose: The purpose of this exercise is to set the serial structure in operation. The In Operation status is not necessary to do maintenance planning, but it is necessary to register operational values on the serial.

Prerequisite: The previous lessons must be completed.

Windows:
Serial Structure Information

Steps: To complete this exercise, perform the following steps.

  1. Open the Serial Structure Information window.
  2. Query (F3) for your A/C, Serial Number nX30000.
  3. Right-click in the window header and click Set Structure In Operation.
  4. Click either the Consist Of tab or the Multilevel tab and verify that all serials in the structure have an operational status of In Operation. (If any serial had an operational condition of Non Operational, the operational condition was also changed to Operational.) 

Maintain Access Rights on a Serial Structure 

Purpose: The purpose of this exercise is to learn how to grant and revoke an access group on a selected top serial, and to extend (spread) the selected access group to all serials at all levels. In this lesson we will grant the access group SYSOWN for your part number nX32NLG7001, revision * and serial number nX31000. For the purpose of revoking access we will use the access group you have created as basic data on the same part, revision and serial number.

Prerequisites: The serial(s) for which you want to grant or revoke access must have received access groups from the template level.
