Modifying maintenance program – An overview

This page allows you to edit the details of the selected aircraft maintenance program. Maintenance programs that are in a “Fresh” or “Return” status can be modified in this activity.

This page can also be launched from the “Revise Aircraft Maint. Program” activity for revising programs that are in an “Active” or “Inactive” status. In such cases a new revision of the maintenance program is created in this activity.

You can modify the following details of the maintenance program:

The description of the maintenance program
The category to which the program belongs
The configuration class to which the program is attached

You can also re-define the work units that must be executed as a part of the maintenance program.

Cancel the program

You can cancel the maintenance program in this page. On cancellation, the system cancels the maintenance program and sets the status of the maintenance program to “Cancel”.

Edit the program

If the maintenance program that is modified is in the “Fresh” status, the system modifies the details of the program and retains the same revision of the program in the “Fresh” status. If the status of the program that is modified is “Return”, the system modifies the details of the program, retains the same revision and sets the status of the program to “Fresh”.

Confirm the program

You can also confirm the maintenance program. Once the program is confirmed it cannot be modified further. The status of the program is set to “Confirm”. A confirmed program can be activated or returned for further modification in the “Approve Aircraft Maint. Program” activity.

Revise the program

You can also create a new revision of a program when you launch this page from the “Revise Aircraft Maint. Program” activity. The system creates a new revision of the program with the modified details and sets the status of the program to “Fresh”.

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,

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.
