Create Work Order – A summary of the activity

The “Hangar Work Order” business component helps you to plan maintenance activities. Major maintenance of the aircraft, commonly referred as “Hangar” maintenance, comprises a large number of maintenance activities. This involves extended execution phase in various work centers, interdependencies between work centers and planning of material and resources. Work planning is critical to exercise control over effort and schedule overruns. The “Hangar Work Order” business component facilitates work planning of both routine and non-routine maintenance activities during the hangar maintenance of aircraft.

Work Order

Hangar work order acts as a communication between the planner / supervisor and the execution personnel. The work orders are generated on release of the visit package by the Visit planner to the work center. Work order contains all information pertaining to the maintenance activity(s) to be executed.

A hangar work order contains the following information:

• Maintenance object details: The details of the object on which the activities need to be executed.

• Maintenance activity: The activity(s) that must be executed. Besides describing the various steps involved, the tasks typically carry the point of execution such as ATA, Zone etc. The system sequences the opening and closing access panel tasks and establishes the dependencies. Depending upon the level of urgency, you can assign priority to both work order and tasks.

• Resource requirements: The resources (men, material and facilities) to be expended for accomplishment of the stated activities. Material requirements are communicated thruough “Maintenance Material Request”.

• Schedule details: The expected start and completion dates for the maintenance activity(s).

Types of work orders

Based on the maintenance object and the nature of the maintenance activity, work orders can be classified as:

• Aircraft Work Orders: Work orders created for executing different maintenance activities on the aircraft.

• On-Wing Component Work Order: Work orders created for performing the maintenance activities on the components that are attached to the aircraft.

• Component Replacement Work Orders: Work orders that are created for performing the component replacements.

Sub-work order

During the execution of maintenance activities, more discrepancies (also called as non-routines) might be detected. If the work content of these discrepancies or non-routines is relatively high, they can be executed through ’sub-work orders’. Sub-work orders are created on the main work order and they maintain the reference of the parent work order. You can also split an existing work order into multiple sub-work orders and move a set of tasks from the main work order to a sub-work order.

Work order status

A work order (or work order – task) will have three types of statuses, namely job, authorization and transient status.

The following are the job statuses, which a work order can attain:

• Fresh: All work orders will take this status on creation. This status indicates that all details have not been specified for the work order.

• Cancelled: You can cancel a work order in the ‘Fresh’ status, if not required. However, you cannot cancel a work order generated from a “planned” visit package containing mandatory tasks.

• Scheduled: All work orders will take this status after scheduling. This status indicates that the work order is ready for execution.

• In-Progress: The status of the work order becomes ‘In-Progress’ after, atleast one actual reporting is done or when the status is set to ‘In-Progress’ manually. Once the status is changed to "In-progress", it cannot be reverted back to “Scheduled”.

• Completed: The status of the work order becomes ‘Complete’ after all the assigned tasks are signed off or when it is set to it manually.

• Preclosed: You can preclose a workorder or task without completing it. Preclosing of the workorder or task will stop further usage information being recorded against it.

• Closed: The status of the work order becomes ‘Closed’ after all the reporting is completed and the excess material is transferred to the warehouse or when it is set manually.

• Reversed: If certain controlled set of modifications is made in the “Closed” work order ,then it becomes “Reversed”.

A work order can have the following authorization statuses:

• Not required: Work orders, which do not require authorization, will acquire this status on creation.

• Pending: Work orders which require authorization will acquire this status on creation.

• Authorized: Work orders that are authorized will acquire this status.

• Returned: Work orders which are returned back to the initiator (for modifications) by the authorizer, will be assigned the “Returned” status.

• Deferred: If all the tasks within a work order are deferred, the work order will attain this status.

A work order can have one of the following transient statuses. The transient status indicates a disruption in work progress and is temporary in nature:

• Hold: If the planner wants to hold further processing of some work order, the work order is assinged the “Hold” status.

• Pending Deferral: The status of the work order, when the deferment request is raised and is waiting for approval from the visit planner.

Schedule work order

Raise an engineering service request

Specify parts required for the work order or task

You can modify the quantity of parts required to execute a work order or task.

• Use the “Edit Task Part Requirements” page, to modify the quantity of parts required to execute the individual tasks in a work order.

• Use the “Edit Work Order Part Requirements” page, to modify the quantity of parts required to execute the work order.

Specify resources required for the work order or task

You can modify the resources that are estimated for the execution of the work order or task.

• Use the “Edit Task Resource Requirements” page, to modify the resources required for the individual tasks in a work order.

• Use the “Edit Work Order Resource Requirements” page, to modify the resources required for the work order.

Record reference information for the work order

You can modify the reference information for the work order. Reference information includes a list of documents or manuals, which are referred for the maintenance activities.

• Use the “Edit Reference Information” page, to record the reference information for the work order.

Schedule work order

The work order or the individual tasks of the work order can be scheduled.

• Use the “Schedule / Re-schedule Work Orders” page, to schedule or reschedule the work order.

Raise an engineering service request

You can create an engineering service request (ESR), to communicate the request for clarifications to the respective engineering cell on a maintenance object. The details of the aircraft, components, reference documents and work center are provided in the ESR.

• Use the “Create ES Request” page, to create an ESR.
