If a component is removed from an aircraft or component assembly by CR transaction, and if the “Removal Date” and “Removal Time” is modified to a later date and time, the system ensures that the same component is not currently attached to any other aircraft or component assembly.

The system performs the following on clicking the “Amend” pushbutton:

Ensures that the condition of the installed component is "Serviceable", “New” or “Overhauled” in the “Aircraft “ business component, when the “Source of Installed Comp” is set to “Inventory” or “Cannibalisation”.
If the “Check whether assembly status is completed” option is set to “Yes” in the “Set Options” activity, then the system verifies whether the assembly status of the installed part number and serial number is “Complete” in the “Configuration” business component.
If a value is entered in the “Component #” or “Part #” and “Serial #” fields, then the system ensures that the stock quantity of the “Part #” and “Serial #” or “Component #” is "NIL" in the “Stock Maintenance” business component.
If “Removal Date”, “Removal Time” or “Installation Date & Time” is changed for a component replacement transaction, the system accordingly updates the parameter values for the component in the “Aircraft” business component.
If the “Reason #”, “Removal Type” and “Basic Removal?” details are entered, then the system updates the CR document with the defined values.
If the “Reason #” is entered by the user and the “Removal Type” and / or “Basic Removal?” details are not entered, then, on confirmation of CR, the system updates the “Removal Type” and “Basic Removal?” values with the values defined for the corresponding ‘Reason #’ in the “Maintain Reasons for Removal” activity of the “Common Masters” business component.
Updates the configuration history with the component removal details. The system also updates the replacement history with the component removal details, installation details and replacement details.
If there is a change in the parameter value of the removed and/or installed component or any of its lower level children as on the current date and transaction date, the system updates the schedule details accordingly in the “Component Maintenance Program” business component.
Before the amendment, if the status of the component replacement is “Removed”, the system updates the replacement history with the removal details. If the status of the component replacement before amending is “Replaced”, the system updates the replacement history with the replacement details.
Updates the component condition based on the SOS disposition of the component. When the SOS disposition of the component is changed to “No Fault Found”, the condition becomes “Serviceable”. However, the condition remains unchanged if the SOS disposition is “Suspected Failure” or “Confirmed Failure”.

Amending component replacement details – An overview

In this page you can alter the component removal details for the component replacement transactions that are in the “Replaced” status. The system displays the details of the selected component replacement transaction such as the component replacement transaction number, its status, type and number of the source document and the station at which the replacement was done.

You can record the SOS disposition for a component during amendment of component replacement. This refers to the revised condition of the component that could be Suspected Failure, Confirmed Failure or No Fault Found. Based on the SOS disposition, the system automatically resets the condition of the component in the following way,

If the SOS disposition is No Fault Found, the condition of the component becomes Serviceable. Subsequently, the component is attached to the aircraft.
If the SOS Disposition is Confirmed Failure or Suspected Failure, the condition of the component is reset to Unserviceable. Subsequently, you can perform required action such as creation of CWO/Repair Order.

Note: The details can be amended only if no component work order has been raised on the removed part and the serial number.

The parent of the replaced component, and the component removal and installation details can also be viewed in this page.
