You can use this tab to modify the component removal and installation details.

Note: On page launch, the following fields are enabled only if the status of the Component Replacement # is other than “Removed” or “Replaced”.

Removed Part #

The part to be removed. (Alphanumeric, 40). Ensure that the part number entered here is a valid part defined in the “Part Administration” business component.

Help facility available.

Removed Serial #

The serial number of the part to be removed. (Alphanumeric, 40).

Help facility available.

Removed  Component #

The component ID of the removed part number and the serial number. (Alphanumeric, 40). Ensure that the component number entered here is a valid component defined in the “Aircraft” business component.

The component number specified must be attached to a Next Higher Assembly as defined in the “Configuration” business component.

Help facility available.

Note: The Removed Part #, Removed Serial # and Removed Component # must be entered only for removal and replacement transactions.

Note: If the Removed Part # and Removed Serial # are specified, the Part # - Serial # combination must be defined in the “Stock Maintenance” business component.

Note: Ensure that the Part # - Serial # combination is same as the Part # - Serial # combination identified for the Removed Component # in the “Aircraft” business component.

Note: If the Removed Component # is not specified, ensure that the Removed Part # - Removed Serial # combination is attached to a Next Higher Assembly (either Aircraft or any NHA Component) as defined in the “Configuration” business component.

The system displays the following fields in the “Removal Details” group box:

Part Description

The textual description of the removed part.

ATA #

The ATA chapter of the position code to which the removed part is associated. This indicates the system in which the part replacement is being done.

To perform a component removal transaction

Tag #

The tag number to be attached to the component after its removal from the aircraft (Alphanumeric, 18).

Component Condition

Use the drop-down list box to specify the condition of the removed component, which could be “Serviceable” or “Unserviceable”. The system sets the field to “Unserviceable” by default.

 

The system displays the following fields:

Attachment Status

The attachment status of the position code, which could be one of the following:

  • Attached – Indicates that the component is attached to the position code.

  • Removed – Indicates that no component is attached to the position code.

  • New – Indicates that the position code is newly created.

  • Unknown – Indicates that the serial number of the component attached to the position code, is unknown.

  • Error – Indicates that the component attached to the position code is different from the intended component.

 

  • Modify the following fields only when the component replacement transaction is in “Fresh”, “Error-Removed” or “Error-Replaced” status:

Removal Date

The date on which the component is removed from the position code (Date Format). Ensure that the date entered in this field is in the format displayed in the “Date & Time Format” field and is earlier than or equal to the current server date.

Removal Time

The time at which the component is removed from the position code (Time Format).  Ensure that the time entered in this field is in the format displayed in the “Date & Time Format” field and is earlier than or equal to the current server date.

Note: The system ensures the following:

  1. If the attachment status of the position code is other than “Unknown”, the removal date and time must be later than the previous installation date and time of the removed component as available in the configuration history.

  2. The removal date and time must be later than the induction date and time of the removed component, as available in the “Aircraft” business component.

  3. The removal date and time must be earlier than the installation date and time of the installed component.

  4. The removal date and time must be later than the initialization date and time of the removed component parameter value as available in the parameter value history, in the “Aircraft” business component.

If any of the above conditions is not satisfied, the system generates an error log, which can be viewed by clicking the “Error Log” tab.

Removed By

The code identifying the employee who has removed the component (Alphanumeric, 15). Ensure that the employee number has already been defined in the “Employee Information” business component and is in “Active” status.

Help facility available.

Removal Type

Use the drop-down list box to modify the type of removal. The following options are available:

  • Scheduled - Indicates that the component is removed to carry out preventive maintenance operations such as lubrication, or the component removal is a scheduled removal. The schedules can be based on intervals, consumption or predictive triggers.

  • Unscheduled - Indicates that the component is removed to carry out maintenance activity based on the outcome of equipment parameter inspections or on the breakdown of the equipment.

  • Others - Cases of robbery can be categorized as “Others”.

The system defaults this field with the previously saved value.

Basic Removal

Use the drop-down list box to classify the removal as ‘Basic’ or ‘Non basic’. The following options are available:

  • Yes - when the component is removed due to a problem in the same component.

  • No - when the component is removed for accessibility reasons, that is, for removal of another component.

The system defaults this field with the previously saved value.

Reason #

The reason for removing the part from the position code.. The reason for removal must have already been defined in the “Create Reasons for Removal” activity under the “Common Masters” business component.

Help facility available.

Remarks

Any descriptive reasons or remarks for the removal of the component (Alphanumeric, 255).

Note: If any discrepancies have been reported against the removed part number and, serial number or component number in the “Discrepancy Processing” business component, the system retrieves these details and stores it against the component replacement transaction number.

The system performs the following:

  1. Updates the CR status to “Fresh”.

  2. Updates the attachment status of the position code to “Removed”, if the position code is empty.

  3. Updates the attachment status of the position code to “Attached”, if the position code is filled.

Note: The attachment status of the position code will not be updated if the same position code exists with attachment status “Error” in any other component replacement transaction.

For more information, see “View Error Log Details” page.

Restrictions on part/serial replacement

You cannot attach part #/serial # to a NHA/aircraft during the effective period, if the process parameter “Allow Component Attachment?” for the restriction code of the part #/serial # is ‘No’.

Similarly, you cannot remove part #/serial # from a NHA/aircraft during the effective period, if the process parameter “Allow Component Removal?” for the restriction code of the part #/serial # is ‘No’.

On the contrary, if the restriction code of the part#/serial # allows component attachment/removal, the system proceeds with replacement.

 (You can place restrictions on attachment/removal of part#/serial# in the “Manage Part Restrictions” activity of Aircraft by associating a restriction code that does not allow attachment/removal during the period between Effective From and To dates. Restrictions placed on part # via the restriction code apply to all serial #s of the part. Restrictions can also be placed on a specific serial # or on a range of serial #s of a part. Process parameters of restriction codes determine whether they facilitate component replacement. And these are defined in the “Set Process Parameters” page of “Define Process Entities” activity of Common Master.)

Note: For an empty position code, you can confirm the component removal only if the attachment status of the position code is “Unknown”.

Note: The system will not allow two or more users to simultaneously update the same component replacement details, for the same part number. Also, the system does not allow removal transaction if the position identified by the specified position code in the aircraft configuration, is empty.

The system performs the following on confirming the removal transaction:

  1. If the “Reason of Removal” is “Cannibalisation”, the system modifies the condition of the aircraft to “Under Maintenance”.

  2. Sets the CR status to “Removed” and sets the “Rem Confirmed By” and “Confirmed Date” fields to the name of the currently logged in user and the current server date.

  3. Updates the “Configuration” business component with the removed part and the serial number for the position code.

  4. If the attachment status of the position code is “Unknown”, then on confirmation of removal, the system updates the attachment status of the position code to “Removed” in the “Configuration” business component. This updation will not happen if any other “Error-Removed” or “Error-Replaced” CR exists for the same position code.

  5. Updates the “Replacement history” in the “Configuration” business component with the transaction number and the removed part number and serial number.

  6. Updates the condition of the removed component in the “Aircraft” business component.

  7. Generates the warranty claim for the removed part and serial number or removed compoent,  if you have set the “Automatic Generation of Warranty Claim” field to “Yes” in the “Set Options” activity, and if the part number and serial number or component has a warranty reference number in the “Confirmed” status on the date of removal in the “Component Warranty” business component, and the component  is within the warranty period.

  8. Generates the warranty claim when  the status of the document is changed from “Fresh”  to “confimed”.

  9. If discrepancies have been reported against the removed part number and serial number or component number in the “Discrepancy Processing” business component, the system retrieves these details and stores it against the component replacement transaction number.

  10. If the aircraft assembly is mapped to supplier as “PBH” and the part number that is removed from the assembly is identified as “PBH”, then the system updates the “Ownership” of the component as “Supplier” and “Possession Status” as “PBH”. For the part that is not attached to the aircraft, the system updates the ownership as “Supplier” if the part that is being removed is a child of a component which is identified as “PBH” and if the serial number for that part is available in the PBH supplier list.

  1. If the Status of the Component Replacement # is changed to “Removed”.

  2. 'Source Document Type' js "A/C Maint. Exe. Ref #'.

  3. Status of the 'Source Document # ' is other than “Closed”.

  4. Status of the Task # or the Discrepancy # against which the Component Replacement is carried out is other than “Closed” and “Preclosed”.

For more information, see “View Error Log Details” page.

Source of Installed Comp

Use the drop-down list box to specify the source of the installed component. The following options are available:

  • Inventory - The installed component is taken from the inventory.

  • Cannibalization - The installed component is taken from some other aircraft.

  • Swap – The installed component is swapped between the current aircraft and some other aircraft.

  • Others – The installed component is taken from anywhere else.

The system leaves the field blank by default.

If the source document type is “Technical Log”, then by default, the system sets the field to the source of the CR transaction created for the technical log in the “Replace Components” page of the “Flight Log” business component.

The system displays the following field:

Attachment Status

The attachment status of the position code, which could be one of the following:

  • Attached – Indicates that the component is attached to the position code.

  • Removed – Indicates that no component is attached to the position code.

  • New – Indicates that the position code is newly created.

  • Unknown – Indicates that the serial number of the component attached to the position code, is unknown.

  • Error – Indicates that the component attached to the position code is different from the intended component.

 

  • Enter the following fields:

Installed Part #

The part number to be installed in place of the part specified in the “Removed Part #” field (Alphanumeric, 40). The part should be in “Active” status.

The part number must have already been defined as the alternate part number, for the remoevd part and position code, in one of the following:

  • “Part Administration” business component

  • The “Position Based Parts Interchangeability Rule Definition” page of the “Maintain Model Configuration” or “Maintain Aircraft Configuration” activity under the “Configuration” business component

  • The “Intermixing Rule Definition“ page of the “Maintain Model Configuration” or “Maintain Aircraft Configuration” activity under the “Configuration” business component.

If the source document has a reference to an engineering order (EO) suggesting configuration changes, then the system ensures that the isntalled part is as suggested by the EO or is an alternate part for the part suggested by the EO.

If the Removed Part # and Removed Serial # has Component Ownership as “Customer”, ensure that the Installed Part has “Alternate Type” defined as “Customer Specific” for that customer, in the “Part Administration” business component.

The above statements are true only if the “Config. Control Basis” drop-down is set as “Config. Rules” in the “Build Aircraft Configuration” activity of the “Configuration” business component.

Ensure that the Installed Part # is effective or conditionally effective to the aircraft or the higher assembly maintenance object.

The system ensures that the part configuration is in “Active” status as on the installation date and time entered.

If any of the above conditions are not satisfied, then the system will generate an error log, which can be viewed by clicking the “Error Log” tab in this page.

Help facility available.

Installed Serial #

The serial number of the installed part (Alphanumeric, 40). The serial number must be a valid number for the part as identified in the “Aircraft” business component.

If the “Restriction Type” is set as “Permitted” in the “Edit Permitted Serial # List” page of the “Configuration” business component, the serial number entered here must lie within the “From MSN #” – “To MSN #” range specified for the part number in the “Edit Permitted Serial # List” page. If this condition is not satisfied, the system generates an error log.

Help facility available.

Note: If the component replacement has resulted from a technical log or a hangar work order and if the installed part is taken from “Inventory”, ensure that an issue transaction is raised for the part on the source document, before the date of installation.

Installed Component #

The component ID for the part number and the serial number combination (Alphanumeric, 90). Ensure that the component ID is already defined in the “Aircraft” business component and is in “Active” status. The component ID must be a valid component ID for the part and serial number entered in the “Part #” and “Serial #” fields.

If this field is left blank, the part number entered in the “Part #” field should exist in "Reference Part" of the "Part Administration" business component, if the “Source of Installed Comp” field is set to an option other than “Loans”.

Help facility available.

The system fills in the following field on clicking the “Edit CR” pushbutton:

Part Desc

The textual description of the part to be installed.

Installation Date & Time

The date and time on which the component is installed (Date & Time Format). Ensure that the date and time entered are in the format displayed in the “Date & Time Format” field and is equal to or later than the date entered in the “Removal Date” field, and earlier than or equal to the current server date.

If the “Default Removal Date and Time based on source document” option is set to “Yes” in the “Set Options” activity, the system displays the date specified in the source document. Else, the system displays the current server date and time by default.

Note: The system ensures the following:

  1. The installation date and time must be later than the induction date of the installed component, as available in the “Aircraft” business component.

  2. The installation date and time must be later than the initialization date and time of installed component parameter value available in the parameter value history, in the “Aircraft” business component.

 If any of the above conditions is not satisfied, the system generates an error log.

Installed By

The number identifying the employee who has carried out the installation (Alphanumeric, 15). Ensure that the employee number has already been defined in the “Employee Information” business component and is in “Active” status.

Help facility available.

Acceptance Ref.

The acceptance reference may be a document or a text, entered while attaching a part to aircraft. (Alphanumeric, 255).

While attaching a part to an aircraft or a Component, the system ensures that the Part # of the installed Component is effective to the Aircraft / Component #. Some parts are identified as Effective to Aircraft or Component based on specific conditions. If the “Effectivity Status” of the installed part or the part # of the child component attached to installed part # / installed serial #, is set as “Conditional Effective” for any of the higher assembly maintenance object, then as authentication for verification of the conditions before attachment, system will mandate an Acceptance Reference.

The Effectivity Status of the part is defined in the “Manage Part Effectivity” activity of the “Aircraft” business component.

The system displays the following field:

Effectivity Notes

Any additional information on the effectivity or suitability of the part to aircraft or component. The system displays the Effectivity Notes which are identified during confirmation of Component Replacement.

The field displays the string “View Effectivity Notes” which is hyperlinked to launch the “View Maintenance Info. for Part” page which displays the maintenance information of the part.

Comments

Any additional remarks pertaining to the installation of the component (Alphanumeric, 255).

Note: The system will not allow two or more users to simultaneously update the same component replacement details, for the same part number.

  1. Updates the CR status to “Fresh”, if removal details are not entered.

  2. Updates the CR status to “Removed”, if removal details are entered.

  3. Updates the attachment status of the position code to “Removed”, if the position code is empty.

  4. Updates the attachment status of the position code to “Attached”, if the position code is filled.

Note: The attachment status of the position code will not be updated if the same position code exists with attachment status “Error” in any other component replacement transaction.

Note: The system will not allow two or more users to simultaneously update the same component replacement details, for the same part number.

Ensure that the component replacement transaction is not in “Cancelled”, “Error-Removed” or “Replaced” status.

The system performs the following on confirming the component replacement transaction:

  1. Sets the status to “Replaced” and sets the “Repl Confirmed By” and “Rem Confirmed By” fields to the name of the currently logged-in user. Also, the “Rem Confirmed Date” and “Confirmed Date” fields are set to the current server date.

  2. Updates the “Configuration” business component with the installed part and the serial number for the position code. The system also updates the attachment status of the position code as “Attached”. The configuration details will not be updated if the record mode is set as “Error” or if the same position code exists with attachment status “Error” in any other component replacement transaction.

  3. Updates the “Replacement history” in the “Configuration” business component with the transaction number and the installed part number and serial number.

  4. If the status of the component replacement transaction is “Removed”, the system updates the removal details  in the “Configuration” business component and in the replacement history.

  5. The system generates the warranty claim for the removed part and serial number or component number if you have set the “Automatic Generation of Warranty Claim” field to “Yes” in the “Set Options” activity, and if the part number and serial number or component number has a warranty reference number in the “Confirmed” status on the date of removal in the “Component Warranty” business component, and the component is within the warranty period.

  6. The system generates the warranty claim when  the status of the document is changed from “Fresh” to “Confirmed”.

  7. If a component is attached to the aircraft, the system udpates the ownership of the component as “Owned” and possession status as blank, in the “Aircraft” business component.

  8. If the aircraft assembly is mapped to supplier as “PBH” and the part number that is removed from the assembly is identified as “PBH”, then the system updates the “Ownership” of the component as “Supplier” and “Possession Status” as “PBH”. For the part that is not attached to the aircraft the system updates the ownership as “Supplier”, if the part is a child of a component which is identified as “PBH” and if the serial number for that part is available in the PBH supplier list.

  9. Updates the schedule details for the component in the “Component Maintenance Program” as follows:

  1. For the components (or any one of the child components) having calendar-based schedule and “Updation Basis” as “Date of Attachment”, the system adds the schedule interval to the current replacement date and updates the resulting value as “Next Schedule Date”, if the “Next Schedule Date” is left blank. The system also updates the attachment date if the “Attachment Date” field is left blank.

  2. If the component is attached to an aircraft and if the installed component or any of its child components has position-based schedules  the system adds the position-based interval to the last schedule date/value of the work unit for the respective component in the position.

  3. For usage-based schedule, the system adds the schedule interval to the last performed value and considers the resulting value as “Next Schedule Value”.

Note: The system performs this updation only for those parameters that are common between usage-based schedules for position code and usage-based schedules identified for the component.

For date-based schedule, the system checks the updation basis. If the “Updation Basis” is selected as “Attached Date”, then the system adds the schedule interval to the attached date to obtain the “Next Schedule Date”. If the “Updation Basis” is selected as “Last Performed Date”, then the system adds the schedule interval to the last performed date.

  1. Updates the “Warranty Start Date” in the “Component Warranty” business component with the “Installation Date”, if the “Warranty Begins On” field for the attached component or child component is set as “Installation Date” in the “Create Component Warranty Agreement” activity of the “Component Warranty” business component.

Note: This update happens only if the “Warranty End Date” is blank.

  1. Generates serial number for the “Manufacturer Serial #” and accordingly updates the “Stock Maintenance” business component, if the “Part #” is identified to be serial-controlled.

  2. Updates the position formula (if it exists for the attached position) for the component, if the parameter source of the component is set as “Calculated”.

  1. If the Status of the Component Replacement # is changed to “Removed”.

  2. 'Source Document Type' js "A/C Maint. Exe. Ref #'.

  3. Status of the 'Source Document # ' is other than “Closed”.

  4. Status of the Task # or the Discrepancy # against which the Component Replacement is carried out is other than “Closed” and “Preclosed”.

For more information, see “View Error Log Details” page.

Impact on inheritance of position based schedules by attached components

1

NSD / NSV, if manually specified by users in the maintenance program of the attached components are retained in the absence of LPD and LPV

0

The position based schedules overwrite the maintenance program schedules of attached components

Restrictions on part/serial replacement

The system does not allow removal/attachment, if the part/component is a restricted part with a restriction code that has the process parameter “Allow Component Attachment” under the entity type Stock Restriction Code in the Define Process Entities activity set as 0/No during the restriction effective period.

 (You can place restrictions on attachment/removal of part#/serial# in the “Manage Part Restrictions” activity of Aircraft by associating a restriction code that does not allow attachment/removal during the period between Effective From and To dates. Restrictions placed on part # via the restriction code apply to all serial #s of the part. Restrictions can also be placed on a specific serial # or on a range of serial #s of a part. Process parameters of restriction codes determine whether they facilitate component replacement. And these are defined in the “Set Process Parameters” page of “Define Process Entities” activity of Common Master.)

To cancel a component replacement transaction

Note: The system will not allow two or more users to simultaneously update the same component replacement details, for the same part number.

The system ensures that the component replacement transaction is in “Fresh” status and sets the status of the transaction to “Cancelled”.

When you click the “Cancel CR” pushbutton, the system performs the following if the status of the CR being cancelled is “Error-Removed” or “Error-Replaced”:

 Note: If any error CR is available for the same position code, the system will retain the Attachment Status as “Error”.

    1. If there are no CR #s available for the same Removed Part # and Removed Serial # with “SOS Disposition” set as “Suspected Failure” or “Confirmed Failure” in the current business component.

    2. If the option “Receipt Inspection for SOS based Serviceable Parts” is set as “Not Required” in the “Set Options” activity of the “Stock Maintenance” business component.

To proceed carry out the following:
