MCR #	The MCR number for which the weight and balance details must be defined.
Revision #	The revision number of the MCR, if any.
Subject	The textual description of the MCR.
Source Doc Type	The type of the source document to which the MCR belongs.
Part Identifier	The identifier of the part as defined in the “Create Maintenance Change Request” page, which could be one of the following:
	Internal - indicates that the MCR must be executed on the part which is already available with the operator. This internal part is already defined in the "Create Parts Main Information" activity of the "Part Administration" business component.
	Supplier - indicates that the MCR must be executed on the part supplied by the supplier. This part can be a new part or an alternate part that is defined in the "Maintain Alternate Part Nos" activity of the "Part Administration" business component.

Enter the following field in the “Group Details” group box:

Applicability Group #

Use the drop-down list box to select the group of aircraft, component or engine for which the MCR is applicable. The system lists the group numbers created in the “Aircraft Effectivity” page if the MCR is applicable for “Aircraft” or the group numbers defined in the “Component Effectivity” page if the MCR is applicable for “Component” or “Engine”.

Leave this field blank, if you wish to enter the weight and balance details with respect to the MCR and revision number combination.

Click the “Get Details” pushbutton to retrieve the weight and balance details that have already been defined for the applicability group.
Click the “Get Parts” pushbutton to retrieve the part details.

The system displays the multiline fields if the weight and balance details have already been defined for the applicability group.

Enter the following fields in the “Weight & Balance Details” multiline to record parts modified and changes in weight and balance of the aircraft:

Part #

The modified part number that led to the change in the aircraft weight and moment (Alphanumeric, 40). Mandatory. Ensure that the part number is unique in the multiline.

Help facility available.

Note: If you have already defined the weight and balance details for a particular applicability group, then ensure that the part number is not defined across the applicability groups.

The system displays the following field on clicking the “Edit Weight & Balance Details” pushbutton:

UOM

The unit of measurement for the aircraft weight.

Enter the following field:

Change In Weight

The change in weight of the aircraft after the execution of the MCR (Decimal). Mandatory.
