This page allows you to create a DMR for deferring a work unit. On creating the request. Tell me more.

Select the “Defer Discrepancies” link in the “Process Discrepancies” page.

The “Discrepancy Deferral Report” page appears.

The system displays the following field in the “Maint Report Details” group box:

Maint Report #

The maintenance report selected in the previous page.

Enter the following field:

Numbering Type

Use the drop-down list box to select the numbering type to be used by the system for generating the deferred maintenance report (DMR) number. The system lists all the numbering types created in the “Create Numbering Class” activity of the “Document Numbering Class” business component that are valid on the current date. By default, the system sets the field to the numbering type specified as default for the “Maint_Report” transaction.

The system displays the following fields:

Help facility available.

The system displays the following field:

Fault Description

The textual description of the fault.

Zoom facility available.

Enter the following field:

Cause #

The code that identifies the cause for the fault (Alphanumeric, 25). Ensure that this number is defined in “Create Fault Codes” activity of “Fault Isolation Manual” business component and is in the “Active” status.

Entry in this field is mandatory, if the “Fault # “ field is entered

Note: If the cause is entered, then the fault code must be entered. The combination of fault and cause must be defined in the “Fault Isolation Manual” business component.

The system displays the following field:

Cause Description

The textual description of the cause.

Zoom facility available.

Click the “Get Details” pushbutton, to retrieve all the work units for the fault code and cause code.
Enter the following fields in the “Work Unit Details” multiline:

Seq #

The sequence in which the tasks should be performed while executing the work order (Integer). Ensure that the sequence number is a positive integer and is unique in the multiline.

	If you leave the sequence number blank, the system automatically assigns a sequence number to each row, in the order in which they are entered in the multiline, on clicking the “Create Report” or “Confirm Report” pushbutton. Ensure that you do not leave it blank for any of the tasks occurring in between.
Work Unit #	The number identifying the work unit (Alphanumeric, 30). Ensure this number is already defined in the “Create Task” or “Create Standard Procedure” activity of the “Maintenance Task” business component and is in the “active” status.

Note: Work units must be in “Active” status. Ensure that atleast one work unit is entered for the maintenance report.

Work Unit Type	Use the drop-down list box to specify the type of the work unit. The system provides the following options:
	Task - Select this option to indicate that a task must be performed to rectify the discrepancy.
	Std. Procedure – Select this option to indicate that a standard procedure must be performed to rectify the discrepancy.
	The system sets the field to “Task” by default.

Note: Ensure that the work unit type selected above is already defined for the work unit in the “Fault Isolation Manual” or “Maintenance Task” business component.

The system displays the following fields:

Task Category	The category to which the task belongs.
Work Unit Desc	The textual description of the work unit.

Click the “Re–Number” pushbutton to renumber the work units in the multiline.
If you wish to insert work units in the multiline and assign sequence number for them, click the “Re-Number” pushbutton to rearrange the existing rows in the ascending order of the sequence number. The system regenerates the sequence number in multiples of five, thereby enabling you to specify the sequence number for the newly added work units.
Check the box in the “Select” column of the multiline to select the work units.
Enter the following fields in the “Deferment Reason Details” group box:

Deferral Type	Use the drop-down list box to select the type of carry forward. The system provides the options “CDL”, “MEL” and “Pax Cabin”. The system leaves the field blank by default.
	Select “CDL”, if the carried forward part belongs to the Configuration Deviation List (CDL). CDL refers to the list of secondary parts, of the airframe and engine that do not affect the flying of the aircraft.
	Select “MEL”, if the carried forward part belongs to the Minimum Equipment List.. MEL refers to Minimum Equipment List approved by the local airworthiness authority, which may remain in an unserviceable state for a certain period, but still provide an acceptable level of safety in the operation of the aircraft.
	Select “Pax Cabin”, if the carried forward part belongs to pax cabin.
Reason for Deferral	Use the drop-down list box to select the reason for deferment. The system lists all the “active” quick codes of type “Reason for carry forward” as defined in the “Add Quick Codes” activity of the “Discrepancy Processing” business component. The system leaves the field blank by default.
Deferral Item #	The number identifying the item being deferred (Alphanumeric, 150).
Item Description	The textual description of the item being deferred (Alphanumeric,255). Zoom facility available.

The system displays the following:

Maintenance Implications

The implication of the deferral, on the maintenance of the aircraft.

Zoom facility available.

Operational Implications

The implication of the deferral, on the operation of the aircraft.

Zoom facility available.

Conditions

The condition of the aircraft

Zoom facility available.

Enter the following:

Comments

Any additional remarks pertaining to the reason for carrying forward the work units (Alphanumeric, 255).

Zoom facility available.

Click the “Create Report” pushbutton to create deferral report for the selected work units.

The system generates the DMR number and sets the status of the DMR as “Fresh”.

Click the “Confirm Report” pushbutton to confirm the deferral report for the selected work units.

The system sets the status as “Confirmed”. If the “Authorization of Deferrals” in the “Set Options” activity is set as “Not Required”, the system updates the “Processed (Y / N)” flag as “No” and the “Deferred (Y / N)” flag as “Yes”. Otherwise, the system updates the “Processed (Y / N)” flag as “Yes” and the “Deferred (Y / N)” flag as “No”.

To proceed, carry out the following

Select the “View Associated Discrepancies” link to view the associated discrepancies.
Select the “Edit Deferral Limits” link to modify the deferral limits for the selected work units.

Creating or confirming deferral report for discrepancies – An overview

In the Aviation industry, rectification may not be carried out as and when faults are identified. The mechanic may defer the maintenance work on faulty parts or components due to reasons such as non-availability of spares, ill-equipped maintenance station or to prevent disruption of the flight schedule. In such cases, the maintenance report is called “Deferred Maintenance Report” (DMR)and the discrepancy is termed as “Carried forward”.

This page allows you to create a DMR for deferring a work unit. On creating the request, the system generates a DMR number. You can specify the numbering type for the DMR. You can specify the carried forward type, reason category and the reason for carrying forward the maintenance activity.

Note: You can defer a discrepancy only when the option “Deferments of Discrepancies” is set as “Allowed” in the “Set Options” activity.

On creating the DMR, the system sets the status of the deferment request to “Fresh”. You can also confirm the DMR, in this page. Before confirming the deferment, you must specify the deferral limits for the maintenance report.

What you can do in this activity

Specify the work unit type

Specify the carry forward type

Specify the work unit type

You can specify the type of the work unit that is executed, to rectify the discrepancy.

In the “Work Unit Details” multiline,

Set the “Work Unit Type” as “Task”, if a task is performed to rectify the discrepancy.
Set the “Work Unit Type” as “Std. Procedure”, if a standard procedure is performed to rectify the discrepancy.

Specify the carry forward type

A mechanic may defer the rectification of discrepancy due to various reasons. Such discrepancies are termed as “Deferrals”. You can specify the type of carry forward while creating or confirming the deferral report.

Set the “Deferral Type” as “CDL”, if the deferred part belongs to CDL.
Set the “Deferral Type” as “MEL”,if the deferred part belongs to MEL.
Set the “Deferral Type” as “Pax Cabin”, if the deferred part belongs to Pax Cabin.
