Task definition revisions

When changes are required on requirement, job card, block, or master panel card task definitions that are in use to create actual tasks for aircraft undergoing maintenance, you create a revision of the affected task definitions. When you create a revision of a task definition, its status changes to Revision. Any actual tasks created are based on the active revision of the task definition, not on the one that is in revision. When you revise a task definition, you can change a lot of information, such as part requirements, labor requirements, task applicability, scheduling information, work type, instructions, and more. However, you cannot the change the following information:

• The assembly, configuration slot and, when applicable, the Replace configuration slot.
• The task class assigned to the definition.
• Previous task links: To change this, you must revise the definition of the previous task.
• Linked from tasks: To change this, you must revise the definition of the linked task.
• The warranty summary: This is associated with the warranty contract, and cannot be changed in a task definition.
• Whether a requirement definition is an executable requirement or not.
• The blocks to which requirement definitions are assigned.

When revising non-executable requirement definitions, the following restrictions apply:

• You cannot remove the associated job card definitions while these job card definitions are active (they must also be in revision).
• The information shown on the Execution tab is for reference and information purposes only, and it is not included in actual tasks created from the requirement definition; you must revise the job card definitions to change the execution information.
