Change Work Unit Status To

Use the drop-down list box to specify the status for the work unit included in the maintenance program. The system provides the options: “Active” and “Inactive”. The system leaves the field blank by default. This inactivates the work unit within the component maintenance program and it will not be taken up for forecasts.

The system displays the following in the “Record Statistics” group box:

Created by

The name of the user who created the component maintenance program.

Created Date

The date on which the component maintenance program was created.

Last Modified by

The name of the user who last modified the component maintenance program.

Last Modified Date

The date on which the component maintenance program was last modified.

Authorized by

Authorized Date

The date on which the component maintenance program was authorized.

Note: 1) The system ensures that there is at least one work unit with maintenance type “Retire”, if the “Lifed?” field is set as “Yes” for the part number, in the “Maintain Maintenance Info. for Part” page of the “Aircraft” business component. 2) You can add or modify a task in the maintenance program only if the maintenance operator associated with the task is also mapped to the login user, if the process parameter "Allow addition/modification of tasks from other Maint. Operator codes in Part Program? under the 'Tech. Records Process Ctrl' entity type and 'Part Prog' entity is set as '0' for No in the Define Process Entities activity of Common Master.

On creation of component maintenance program, the system copies “Revenue” as the expense type for the work units in the component maintenance program, irrespective of the expense type identified for the work units in the part program, if the ownership is identified as “Customer” for the component number. Else, the system copies the expense type identified for the work units in the part program.

If the component maintenance program is in the “Fresh” status, the system updates the details with the current revision number.

The system automatically changes the status of the “Authorized” maintenance program to “Fresh” and increments the existing revision number.

The revision number is also incremented under the following circumstances:

If there is a schedule compliance update request for a work unit from “Component Work Order”, “Hangar Work Order”, “Technical Log” or “Repair Order” business component, the system verifies whether any other work unit of the component is set as precluded work unit in the part program defined for its part of that component, and updates the compliance details of the precluded work units with the compliance details of the precluding work unit.

The system also updates the compliance history for both precluding and precluded work units.

Note: If a new component is inducted into the system and if part program exists in “Authorized” status for the part that belongs to that component, CMP will get initialized with the details of the part program.

If a part program with an EO-based work unit is copied for the same part number but different serial number during automatic creation of CMP, the system updates the part and serial effectivity details defined in the EO and its revision number, for the new serial number in the “Engineering Order” business component.

If the Eng. doc reference # exists for the task, the system allows you to modify the following details of the Eng. Doc. task in the Maintenance Program, only if the process parameter “Allow modification of Eng. Doc. task in Maintenance Program” is set as “Allowed” in the “Define Process Entities” activity of the “Common Master” business component.

On addition of task, schedules are copied from 'Task Master'. Based on the Schedule Type and the schedules copied, the system updates the computation basis controls ‘Next Due Calc. On’, ‘Calc. Ref. Value / Date’ and ‘Last Schedule  Date / Value’ in “Edit Date Based Schedule Information” and  “Edit usage Based Schedule Information” page of the current business component. This is show in the below table:

Scenario

Next Due Calc. On

Calc. Ref. Date

Last Schedule  Date

If NSD is computed based on ‘Manufactured Date’

Mfr. Date

Corresponding Date

Not Applicable

If NSV is computed based  on 'Threshold / Interval Value'

Initial Interval

Not Applicable

If no schedules are copied and for tasks with 'Prog. item Type' "To be Decided"

Blank

Blank

Blank

On addition of ‘One time’ / ‘Recurring’ task, if the task exists in “Maintenance Task” business component, the system computes Next Schedule Date (NSD) and Next Schedule Value (NSV) as follows, based on the value of ‘Reset on Attachment?’:

Reset On Attachment

NSD

NSV

Not Required

NSD = Threshold value + Mfr. Date / Induction date

NSV = Threshold Value

First Attachment

NSD = Threshold value + Component Attachment date and time.

If the component is not attached in an Aircraft, NSD is updated as Blank.

NSV = Threshold Value

Every Attachment

NSD = Threshold value + Component Attachment date and time.

If the component is not attached in an Aircraft, NSD is updated as Blank.

NSV = Threshold Value + Parameter value on Component Attachment date and time

If the component is not attached in an Aircraft, NSV is updated as Blank.

Process Parameter dependency: If the process parameter “Auto Activation/Inactivation of schedule status of  tasks in CMP based on Maint. Operator change?” is set as 1 for Yes under the entity type “Tech. Records Process Ctr” and the entity “Part Prog in the “Define Process Entities” activity of Common Master, the system automatically activates Schedule Status of the tasks mapped to the maintenance operator associated with the component in the maintenance program. Further, Schedule Status of the tasks not related to the maintenance operator will be set as Inactive in the component maintenance program. However, if “Auto Activation/Inactivation of schedule status of  tasks in CMP based on Maint. Operator change?” is set as 0 for No, Schedule Status of the tasks will not be dependent on the maintenance operator.

Note: You can cancel component maintenance program only if it is in the ‘Fresh’ status.
