Define where Instructions should be used

Explanation

This activity is used to define where instructions (operations) are to be used.

Instructions are common definitions of operations with details, that can be used on task types such as interval maintenance, modifications, condition limits, faults, life limits and post maintenance checks. You can define an instruction (operation) to use with one task type exclusively (for instance, one specific type of interval maintenance) or for multiple task types at the same time (for instance, on three different types of interval maintenance, two types of modifications and five types of condition limits). Further, instructions are commonly broken down into more detailed activities often referred to as subtasks. These subtasks can be defined and used on the same task types as listed above. For more information on connecting subtasks to instructions, refer the activity Define Subtasks for Instructions.

Note: The connection between a task type and operation is created automatically when registering an operation in the Instructions/Operations sub tab found in the relevant detail window (e.g., Modification Details). Registering in these tabs is exactly the same as in the Instruction window except that you're working in an overview window instead of a detail window.

Prerequisites

• An operation must be defined for the part revision.  
• To register interval maintenance data for an operation, maintenance codes must be defined as basic data in Maintenance Program Basic Data.
• To register condition limits for an operation, the condition limits must be pre-defined on the part revision.
• In order to connect modifications to an operation, a modification must be defined. Furthermore, parts and part revisions including the part revision for which the operation is created must be assigned to the modification.   
• To connect fault functions to an operation, fault codes must have been connected to the functions of the relevant product model.
• To register instructions for an LLP (life limited part), the part must be defined as an LLP and have stress ratings connected to it.
• To connect post maintenance checks to an operation, the post maintenance check must be defined. Further, the part revision for which the operation is created must be assigned to the post maintenance check.

System Effects

• An instruction (operation) is defined and connected to the task type that is to perform the operation.
• The instruction will be used to remove the expired LLP from its parent structure.
• When pending tasks are distributed (per task type) to a work order, the operation will be copied and connected to the work order.
• If subtasks are connected to the instruction, these can be viewed in the Subtasks tab per task code.

Procedure

Use the following procedure to connect an instruction (operation) to an interval maintenance:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Maintenance Code sub tab.
3. Create a new record (F5).
4. In the Maint Code field, enter the required interval maintenance code. Use the List of Values to select a value.
5. Save the record (F12).

Use the following procedure to connect an instruction (operation) to a condition limit:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Condition Limit sub tab.
3. Create a new record (F5).
4. In the Condition Category field, enter the required condition category. Use the List of Values to select a value.
5. When a condition category is entered, the Condition Code field is populated with the pre-defined value and the condition limit where the instruction (operation) is to be executed is defined.
6. Save the record (F12).

Use the following procedure to connect an instruction (operation) to a modification:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Modification sub tab.
3. Create a new record (F5).
4. In the Mod Code field, enter the modification code for the modification where the operation is to be executed. Use the List of Values to select a value.
5. In the Mod Execution Type field, enter the modification execution type. Use the List of Values to select a value.
6. Save the record (F12).

Use the following procedure to connect an instruction (operation) to a fault function:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Fault Function sub tab.
3. Create a new record (F5).
4. In the Function Number field, enter the required fault function number. Use the List of Values to select a value.
5. In the Fault Code field, enter the fault code. Use the List of Values to select a value.
6. Save the record (F12).

Use the following procedure to connect an instruction (operation) to a life limit:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Life Limit sub tab.
3. Create a new record (F5).
4. In the Stress Rating ID field, enter the required stress rating ID. Use the List of Values to select a value.
5. In the LLP Part Number field, enter the required LLP part number. Use the List of Values to select a value.
6. In the LLP Part Revision field, enter the required LLP part revision. Use the List of Values to select a value.
7. Save the record (F12).

Use the following procedure to connect an instruction (operation) to a post maintenance check:

1. Open the Instruction window and query (F3) for your part revision or for a specific operation.
2. Click the Connect Task Codes tab and then click the Post Maintenance Check sub tab.
3. Create a new record (F5).
4. In the Post Maint Check ID field, enter the required post maintenance check ID. Use the List of Values to select a value.
5. Save the record (F12).
