Base Line?

Check this box to indicate that the engineering change should update the baselined configuration.

Note: The system displays the configuration change details that are already defined for the engineering document and revision number combination.

Enter the following fields in the “Configuration Change Details” multiline:

Existing Part #	The part that must be replaced (Alphanumeric, 40). Mandatory. The part number should have already been identified in the "Create Parts Main Information" of the “Part Administration” business component and the part number must be of the type ”Component” or “Expendable”. Ensure that the part number is unique in the multiline.
Recommended Use	Use the drop-down list box to recommend an action on the part that is replaced. The system provides the following options:
	Discard – Select this option to indicate that the part can be discarded.
	Rework – Select this option to indicate that the part can be reworked upon.
	Others – Select this option to indicate that the part can be kept for other uses.

The system displays the following fields:

Part Description	The textual description of the part.
MCR Part #	The part number identified in the “Edit Configuration Change Information” page of the “Create MCR” activity.
UOM	The unit of measurement for the part.

Enter the following field:

Quantity

The number of parts that must be replaced (Integer). Mandatory. Ensure that the value entered in this field is positive. For parts of type “Component”, the replacement quantity should be the same as the existing quantity.

The system displays the following field:

Part Type

The type of the part, as defined in the “Part Administration” business component.

Enter the following:

New Part #	The part number that will replace the existing part (Alphanumeric, 40). Mandatory. Ensure that this part number is not the same as the part number entered in the “Existing Part #” field. Help facility available.
New Part Description	The textual description of the new part (Alphanumeric, 150). Mandatory.
Quantity	The number of parts that will replace the existing part (Integer). Mandatory. Ensure that the value entered in this field is positive. For parts of type “Component”, the replacement quantity should be the same as the existing quantity.
Interchangeability	Use the drop-down list box to define the part interchangeability. The system provides the following options: One Way – Select this option to indicate that the part numbers are not interchangeable in the same position code. For example, if the part number “P2” has replaced the part “P1” in the position code “PC1”, then “P1” cannot replace the part “P2” subsequently in the same position code. Two Way – Select this option to indicate that the part numbers are interchangeable in the same position code. For example, the part numbers “P1” and “P2” can replace each other in the same position code subsequently. None – Select this option to indicate that the interchangeability of the parts is not allowed. By default, this field is set to “None”.

Note: Ensure that atleast one part is entered in the multiline, and the existing part number is unique in the multiline.

Check the box in the “Select” column of the multiline to mark the part for deletion.
Click the Delete icon provided in the tool bar above the multiline, to delete the parts selected in the multiline.
Click the “Edit Config. Details” pushbutton to update the configuration change details.

The system performs the following, on clicking the “Edit Config. Details” pushbutton:

Depending upon the applicability of the engineering document,

The system checks the availability of the existing part in the aircraft or component configuration for the aircraft and component identified in the “Edit Aircraft Effectivity” and “Edit Serial Number effectivity” pages. If exists, the system copies the respective level code, position code, corresponding part serial number, NHA and the corresponding new part against each aircraft or component.

If the engineering document is applicable for an “Aircraft”, and you have chosen to update model and part configuration after engineering document release or after engineering document execution,

The system checks the availability of the existing part in the model configuration of the aircraft. If exists, the system copies the respective level code, position code, corresponding part serial number, NHA and the corresponding new part against each aircraft or component.

Note: For Expendable parts in the attached components piece part configuration, the system copies the corresponding ‘Position code’, ‘Position Description’, ‘Qty’, and ‘Position Status’.

If the existing part is of type “Piece Part”, the position code details are not copied.

If the engineering document is applicable for a “Component”, and you have chosen to update model and part configuration after engineering document release or after engineering document execution,

The system checks the availability of the existing part in the part configuration. If exists, the system copies the respective level code, position code, corresponding part serial number, NHA and the corresponding new part against each aircraft or component.
If the existing part is of type "Piece Part”, the position code details are not copied.

The system updates the following details in the “Plan Material Requirements” page, if a new part number is entered in the multiline:

If you have chosen to generate PR automatically in the “Create Engineering Document” page, the system copies the part number into the “Plan Material Requirements” page.
The system copies the maintenance bases identified in the “Aircraft” business component, for all the maintenance objects (aircraft or part), into the “Plan Material Requirements” page. The applicability of the engineering document is also considered while copying the maintenance base details.
The unit of measurement of the part entered is copied.
On updating the configuration change details with the New Part #, the system creates new part requirement in “Confirmed” status in the “Confirm New Part Requirements” page. This happens only if the process parameter ‘Auto confirmation of New Part Requirements?’ is set as “Yes” in the “Set Process Parameters” page of the “Common Master” business component.
The required quantity of the part is updated in the “Plan Material Requirements” page as follows:

Reqd. Quantity =

No. Of parts estimated *

No. of maintenance objects maintained in the individual maintenance bases

For example, let us consider a situation where an engineering document requires two numbers each, of Parts P1 and P2, and the engineering document is applicable for 5 aircrafts, where 3 aircrafts are maintained by the “Chicago” maintenance base, and 2 aircrafts are maintained by the “Boston” maintenance base.

In such a case, the Required Quantity for Part P1 in the “Chicago” maintenance base, is calculated as:

Required Quantity = No. of parts * No. of aircraft = 2 * 3 = 6

Similarly, the required quantity is calculated for other parts.

To proceed, carry out the following:

Select the "Edit Model Config. Change Details" link at the bottom of the page to enter the model configuration change details.
Select the "Edit Aircraft Config. Change Details" link at the bottom of the page to enter the aircraft configuration change details.
Select the "Edit Part Config. Change Details" link at the bottom of the page to enter the part configuration change details.
Select the "Edit Component Config. Change Details" link at the bottom of the page to enter the component configuration change details.

Entering configuration changes due to engineering document execution – An overview

The engineering document execution might affect the configuration of the aircraft or the component. This change in configuration might result in the change of the part number itself resulting in a new part number, change in the interchangeability rules for a particular position in the aircraft or component, addition of a new position code, etc. These details are recorded as configuration change information in this page.

You can specify whether the engineering change is applicable or not, for model and part configuration. If applicable, you can indicate whether the configuration must be updated after the release, or execution of the engineering document. You can also indicate whether baselined configurations must be updated. The aircraft and part configuration will be updated only when the engineering document is executed.

You can specify the part number that is to be changed, the recommended action for the changed part number and the number of parts changed. Also, you can enter the new part number, its description, number of parts that replaces the previous parts and the part interchangeability.

The level numbers at which the existing part must be changed, can be specified for the model, aircraft, part or component configurations in the “Edit Model Configuration Change Information”, “Edit Aircraft Configuration Change Information”, “Edit Part Configuration Change Information” and “Edit Component Configuration Change Information” pages.
