Creating maintenance program An overview

You can enter a number for the maintenance program and provide a description for it. You can specify the category to which the maintenance program belongs. You can also provide a reference to the maintenance program that is already defined and copy the maintenance program details.

You can also specify whether the work units for the maintenance program are of type major or minor. The task, standard procedure and work package are the basic work unit types. You can associate multiple work units to the maintenance program in the Maintenance Program multiline and specify the sequence in which they must be carried out. The following details can be specified for the work units in the maintenance program:

The work center where the work unit must be performed.
Whether the execution of the work unit is a major maintenance or a minor maintenance activity.
Whether the maintenance job must be performed on the aircraft or on the components fitted to the aircraft.
The type of the maintenance job, whether Repair, Inspection or Overhaul, that must be performed.
The position code and the level code in the aircraft where the work unit must be executed.
The status of the work unit, which can be Fresh, Active, Inactive or Terminated
Whether the work unit is dependent on the execution of another work unit.
Whether the execution of the work unit can be deferred. If so, the deferment policy must be specified.
When there are multiple schedules defined for the work unit, you can specify whether the earliest schedule or the latest schedule must be considered for executing the work unit.
The type of the expense incurred on the work unit, which can be Revenue or Capital.

The system assigns the Fresh status as soon as the maintenance program is created and sets the creation date and time to the server date and time.

Example: Assume that the following work units, in the form of checks, are defined for the maintenance program:

Work Units - A, 2A, B, C, B, A, 2B.

The system assigns schedule IDs for the checks as given below:

Work Units	Sch #
A	1
2A	1
B	1
C	1
B	2
A	2
2B	1

This enables easy identification of the work unit in the maintenance cycle.
