Analyze Historical Data

Explanation

This activity is used to view historical records, analyze them statistically and make references and/or decisions for a particular vehicle or serial part. Here, you can analyze the entries in order to assist you for the registration of new records or as an improvement for existing data.

Historical data will be recorded when the related prerequisites are fulfilled.

The purpose of collecting historic data is to be able to document the maintenance that has been performed on a serial part, and use this in order to improve the live data in IFS Applications. For example, the Serial Order History window contains the actual performed task cards, with reported time and consumed material for all performed maintenance. This data can be used in order to improve the contents of the Task Card window so that the task cards, resources or material that are no longer used can be removed and new task cards, resources or material can be added. Another way of using the historical data might be to analyze faults that have been repaired on a serial and by means of this be able to know how to repair similar faults. 

For a description of each history element in Fleet and Asset Management, refer to the online help file Historical Data.

Prerequisites

• Changes must have been performed on an active serial structure template before historical data (journal) can be viewed.
• To view replacement history, a component must first be connected, disconnected or replaced in a serial structure. 
• A serial number must be changed for a serial part before identification history can be viewed.
• A serial transportation route must have been completed to view information on serial route history.
• To view vehicle condition history the vehicle condition of a vehicle must have been changed.
• Condition monitoring must have been performed on a serial part before condition limit history can be viewed.
• A modification must have been performed on a serial part to view modification history.
• An interval based maintenance must have been performed on a serial part before interval maintenance history can be viewed.
• A fault on a serial part must have been repaired to view fault history.
• To view entries in the Additional Fault Information window, additional fault information must have been registered on non-serialized parts.
• To view non routine history, there must exist non routine faults that were reported on the work order/work order operation that is included in a work package for a maintenance visit. These non routine faults must have been repaired.
• A maintenance event must have been performed on a serial part. The information here will be recorded as generic history and has specific entries for each event type.
• To view maintenance event cancellation history a running event or the corresponding work order must have been canceled.
• Operational log entries must have been performed on a serial part before operational logging history can be viewed.
• An operational event must have been removed from a vehicle to view the operational planning history.
• To view historical maintenance order information, a maintenance order with connected events must have been completed.
• To view information on performed maintenance, time must have been reported for the personnel, material must have been issued, and sign off completed.
• To view historical flight log information, the closed or voided flight log must have been moved to history.
• To view historical post maintenance check information, the post maintenance check event must have been completed.

Procedure

Follow this procedure to analyze historical data for a serial part.

1. Open the History per Serial window and query (F3) for the necessary serial.
2. Select the appropriate tab that corresponds to the history you want to analyze for a specific purpose.

Follow this procedure to view and analyze details on completed maintenance events:

1. Open the Serial Order History window and query (F3) for the necessary serial.
2. Select the tab(s) containing the data you want to analyze for a specific purpose. Observe the following examples:

• The Order Info tab can be used to view the total cost for the work carried out on the maintenance event. The aggregated cost of all resources and material utilized for the work will be shown.
• The Task Cards/Resources tab can be used to view resources for which time was reported when reporting in work. This information can be used to analyze whether a certain resource group spends more time to do the work than originally plan or whether a planned tool is used as often as expected. As a result, the data in the task library can be adjusted to better reflect actual maintenance requirements.
• The Task Cards/Material tab can be used when you want to view information on the material utilized for the work. This information can be used to analyze any additional material that have been used for the work, and whether the material should be part of the planning data. Adding material to the task library means that it will be possible to reserve or peg material as early as the planning stage of the maintenance order.

Follow this procedure to change the operational parameter values for a completed maintenance event/work order.

1. Open one of the following windows and query (F3) for the information you want to change operational parameters on.

• Serial Modification History List - Right-click and click Details, to view a window with more details. Click the Oper Param tab.
• Serial Order History/Operational Parameter tab.

3. Right-click on the table of the tab and click Change Operational Values. The Change Operational Values dialog box appears.
4. Enter the new values you want in the Value After Overhaul and Value Total fields. Note: The new values entered here are required to be greater than or equal to the previous log value for the serials and smaller than or equal to the next log value of the serial.
5. Click OK.

Follow this procedure to remove obsolete history entries:

1. Open the History per Serial window or the Operational Planning History List window, query (F3) for the required part number.
2. If you have selected the History per Serial window, click the Operational Plan tab.
3. Right-click and click Remove History. A message will appear warning you that all history records up to the given date will be removed. Click YES.
4. The Remove Old History Entries dialog box will open.
5. If necessary, update the date given in the Remove Entries Up Until Date field.
6. Click OK.

Follow this procedure to view and/or analyze historical maintenance orders:

1. Open the Maintenance Order History List window.
2. Populate (F2) or query (F3) for the necessary maintenance order.
3. Right-click on the row, and then click Details. The Maintenance Order History window opens with data on the selected maintenance order.
4. Navigate to the different tabs to view additional information on the historical maintenance order.

Follow this procedure to view the snapshots of a maintenance order:

1. Open the Maintenance Order Snapshot window and query (F3) for the necessary maintenance order.
2. Observe the data in the window and connected tabs.
3. You can right-click on a record in the Task Cards tab, and then click Task Cards to view additional information in the task card.

Follow this procedure to view and/or analyze historical flight logs:

1. Open the Flight Log History List window and populate (F2) or query (F3) for the relevant flight log number and/or serial.
2. Right-click on the record and then click Details. The Flight Log History window opens with information on the selected flight log.
3. Navigate to the different tabs to view additional information on the historical flight log.
