Define Task Card

Explanation

This activity is used to define a task card that can be used on maintenance event types, i.e., interval maintenance, modifications, condition limits, faults, life limits, and post maintenance checks.

There can be one or more revisions of a certain task card. Each task card revision will contain information on the work that is to be performed when serials with the defined part revision are to be maintained. What, where, and the workload of the task card is defined here. Resources, material, zones, sign off requirements, task card criticality, condition measurements, event codes the task card is to be included on, and subtasks can be specified. At creation, the task card revision will automatically receive the Preliminary status. When the task card revision is in this status (or in the Active status) it will be possible to connect the task card to event codes, such as, maintenance codes, condition limits, modification codes, fault functions, life limits, and post maintenance check IDs.

When the workshop receives a maintenance assignment with a distribution type of Work Order or Execution Logic Structure, the task cards for the part revision will be transferred to the work order. Only task cards in the Active status will be transferred to work orders. The status of the task card revision can be changed to Active or Obsolete depending on your requirements. This information is shown in point form in the following table:

Each task card is defined for the specific part revision, e.g., aircraft engine or locomotive bogie, on which the task card is applied. The affected part revision in the structure on which work is to be performed, for instance a pump in the aircraft engine or a wheel on the locomotive, must be indicated. You must also indicate where in the function structure the work is to be performed. If the work is to be performed directly on the part revision (aircraft engine/train), the affected part revision must be the same as the part revision.

The number of required levels in the function breakdown is managed by object property settings. For serial parts, the valid object property is FUNCTION_LEVEL_INSTR. For vehicle parts it is FUNC_LEVEL_INSTR_VEH. Legal values for these settings will be 0, 1, 2 and 3. Object properties can be found in Configuration Basic Data/Object Property tab.

The planned duration of the task card and a description of the work to be performed must be registered.

For each task card, you must specify where the work is to be performed by registering one of the following field combinations:

• Template Part No, Template Part Rev, and Structure Position indicates that the task card is performed on the specific structure position regardless of what is installed in the position. The List of Values displays the possible combinations that exist in the structure of the part number and revision that are entered on the task card.
• Affected Part No and Affected Part Rev indicates that the task card is performed on that part number/revision combination in all places in the structure where the combination exists. The List of Values displays the possible combinations that exist in the structure of the part number and revision that are entered on the task card.
• Template Part No, Template Part Rev, Structure Position, Affected Part No, and Affected Part Rev indicates that the task card is performed on that specific structure position if the specific part number and revision is installed in the structure position. The List of Values for the Template Part No, Template Part Rev, and Structure Position fields display the possible combinations that exist in the structure of the part number and revision that are entered on the task card. The List of Values for the Affected Part No and Affected Part Rev fields display the possible combinations that can be installed in the given structure position (including prime part, template alternates and position alternates).

When registering a new revision of a part that requires new task cards, it is possible to copy the task card information from a previous part revision and then make changes to the task card for the new part revision. It is also possible to copy between revisions of different part numbers to reuse the task cards on parts with the same maintenance needs.

Prerequisites

• A valid part revision must exist.

The following prerequisites depend on the values you will enter on the task card revision:

• When defining task cards, the template structure together with its product, model and function structure must exist.
• Task card types, locations, strategies, and execution phases must exist.

System Effects

• The task card revision is defined.
• Resources, material, zones, sign off requirements, criticality, and condition measurements can be entered on the task card.
• The task card can be connected to maintenance event codes.
• Subtasks can be connected to the task card revision.

Procedure

The following steps describe entering values that are required for creating a task card. Note that the requirement for values in the Function Breakdown area is dependent on defined object property settings. A list of the optional values that can be defined on the task card is described below these steps.

1. Open the Task Card window and create a new record (F5). This procedure can also be run from the Task Cards window and the Serial Part Revision/Task Cards tab.
2. In the Part Number field, enter the part number of the desired part. Use the List of Values to select a valid value.
3. In the Part Rev field, enter the revision of the part by selecting a value from the List of Values.
4. In the Task Card ID field, enter an identity for the task card.
5. In the Revision field, enter the revision of the task card.
6. In the Description field, enter the description of the task card.
7. If the part revision for which the task card is being created is connected to a product model, values for the Product Number and Model Number appear automatically. If not, use the List of Values to select a valid value.
8. The fields Function Number, Sub Function, and Bottom Function describe where in the function structure the work should be performed. The function structure is defined for the product model.
9. In the Duration field, enter the planned duration of the task card, in hours.
10. In the Work Description field, enter a description of the work to be done on the task card.

Optional fields:

1. In the Type field, enter the type of task card. Use the List of Values to select a valid value.
2. In the Location field, enter the location on the serial where the work should be performed. Use the List of Values to select a valid value.
3. In the Exec Phase field, enter the maintenance phase during which the task card will be performed. Use the List of Values to select a valid value.
4. In the Strategy field, enter the strategy to which this task card belongs. Use the List of Values to select a valid value.
5. If the task card is issued by a manufacturer (or similar), enter the manufacturer's task card ID in the Ref Number field.
6. In the Template Part field, enter the template part number and revision (in the adjoining field) of the template to which the affected structure position belongs. Use the List of Values to select a value.
7. If the task card applies to one specific structure position in the template structure, enter the ID of the position in the Structure Pos field. If a value is entered in this field, values for the Affected Part and Affected Part Revision must be entered.
8. In the Affected Part field, enter the part number and revision (in the adjoining field) of the affected part in the structure of the selected part. Use the List of Values to select a value.

Note: Creating task cards for modifications, condition limits, maintenance codes, faults, life limits, and post maintenance checks uses a similar procedure but the Task Cards tab is accessed from different windows (Modification Details/Execution Type Info for modifications, Serial Part Revision/Life Limit for life limits, Task Cards for Maintenance Code for maintenance codes etc).
