Turn checks and service checks

Line maintenance includes creating and scheduling work packages for turn and service checks. The work to be done in a turn or service check is usually specific to aircraft of a specific type.

A turn check consists of the tasks that must be performed between two flights. A service check includes routine maintenance activities that must be performed regularly, usually every 24 to 48 hours. It can be executed during a multi-hour layover at an airport, or during an overnight stop.

Turn and service checks include standard scheduled maintenance and work deferred from previous maintenance visits. As new deferrals occur, or if the destination of the aircraft changes, the scope and/or location of the work package can also change.

You can model turn and service checks like any other type of maintenance visit by creating task definitions and packaging the tasks created from these definitions into work packages that will be scheduled to line locations. This is a repetitive process because turn and service checks are so frequent.

To facilitate the process, you can model turn and service checks as explained in this section; when that is done, maintenance planners or supervisors can quickly create the work packages for turn and service checks manually, or have Maintenix create them automatically by using the Line Planning Automation (LPA) tool.

To use LPA to create turn and service checks automatically, your administrator must configure Maintenix to run LPA.
