Issuing certificate of maintenance

In this page, you can create, authorize or cancel a Certificate of Maintenance for the component work order.

You can issue the certificate of maintenance only

If all the tasks for which the sign–off is required are signed–off
When the component work order is in “Completed” status.

The system automatically generates a CoM number, each time a CoM is issued after the completion of work. This page also enables you to modify an already existing CoM. The system updates the CoM details with the name of the employee who created, authorized or modified the CoM, along with the date.

Select the “Issue CoM” link in the “Component Work Order Selection” page. Alternatively, select the hyperlinked component work order number in the multiline of the same page.

The “Issue Certificate of Maintenance” page appears.

The system displays the following:

Date & Time Format

The format in which the date and time fields are displayed in this page. This format is displayed from the "User Preferences" business component based on the login user ID. In case the format is not defined, the system displays the date and time format from the "Enterprise Modeling" business component by default.

Enter the following in the “COM Details” group box:

COM#

The number identifying the certificate of maintenance.(Alphanumeric,410)

This field must be entered when the “CoM Numbering” field in the “Set Options” activity is set to “Manual”.When the “CoM Numbering” field in the “Set Options” activity is set to “Auto”, the system automatically generates the COM number.

Note: If a CoM number already exists for the selected component, the number is displayed in the “CoM #” field in the “Last Issued CoM Details” group box along with the Component Work Order and CWO Type on which the last CoM was issued. The system saves the details with the last generated CoM number. The system also updates the “Modified by” field with the name of the employee, “Last Modified Date” field with the current server date and changes the CoM status to “Fresh”.

Issuing CoM using Electronic Signature

Insert the smart card into the smart card reader and enter your Personal Identification Number (PIN) in the "User PIN” field.

Follow the instructions listed under the topic "Signing-off using Electronic Signature".

On successful issue of CoM

The system performs the following:

Updates the details with the current server date as the “Created Date” and the CoM status as “Fresh”.
Restricts the issue of CoM for component work orders having job type as “Component”, if the component condition is “Serviceable”. The system also verifies whether any other component work order exists in “Fresh”, “Scheduled” or “In Progress” status for the main component or associated child components of the selected work order.
The system checks whether the main component or associated child components of the selected work order has any overdue date-based and/or usage-based schedules in their component maintenance programs, on the date of issue of CoM.
If the job type of the CWO is “Piece Part” and if the part control type of the piece part is serial-controlled and/or lot-controlled, the system changes the condition of the piece part from "Unserviceable" to “Serviceable”.

Note: The system does not update the condition of those piece parts that are in phased-out condition.

Updates the pending return quantity for the piece parts and make parts for component work orders of job type “Piece Part” or “Make”.

To authorize the CoM

Click the “Authorize” pushbutton, to authorize the CoM for the selected component work order.
Insert your smart card and enter your Personal Identification Number. Follow the steps mentioned under the topic “Signing-off using Electronic Signature”, for authorizing the certificate of maintenance using electronic signature.

The system performs the following:

Updates the status of the CoM from “Fresh” to “Authorized”.
Updates the details with the current server date as the “Authorized Date” and the CoM status as “Authorized”.The system also updates the schedule details of the component work order.

For date-based schedule

Updates the “Last Performed Date” with the date on which the task was completed. Also, if updation basis is "Last Performed Date" with schedule type as ”Recurring” and a floating interval is given, then the system calculates the next scheduled date (floating) by adding the floating interval (converted to the "Day" time unit) to the last performed date. If the Updation basis is ”Installation Date", then the system does not compute the next schedule date.

For usage-based schedule

Updates the “Last Performed Value” for the parameters of the component mapped to the maintenance program number, with the current values for each parameter. If a floating interval is given, then the system calculates the next scheduled value (floating) by adding the floating interval to the last performed value.
Updates both “Last Performed Date” and “Last Performed Value”, if the “Schedule Type” is both date-based and usage-based.
If the source of the CWO is “EO” and if the executed task, of repetitive/recurring type, is newly added to the maintenance program, then the system updates the maintenance program with the last performed date and/or last performed value with the respective details for the component parameters mapped to the maintenance program.
If the maintenance type of the CWO is “Overhaul”, the system updates the condition of the component as “Overhaul”. Otherwise, the condition of the component is updated as “Serviceable”.

Note: If component condition is specified in the “Update Component Condition” page, then the system updates the condition with the specified condition. If the condition of the incoming component is “Phased Out”, then the system does not change the component condition.

If the job type of the CWO is “Piece Part” and if the part control type of the piece part is serial-controlled and/or lot-controlled, the system changes the condition of the piece part "Unserviceable" to “Serviceable”.

Note: The system does not update the condition of those piece parts that are in phased-out condition.

In the “Aircraft” business component, the system resets the following parameters to zero, as follows:

“Since Overhaul”, “Since Repair”, “Since Inspection” and “Since Shop Visit”, if the maintenance type is “Overhaul”.
“Since Repair”, “Since Inspection” and “Since Shop Visit”, if the maintenance type is “Repair”.
“Since Inspection” and “Since Shop Visit”, if the maintenance type is “Inspection”.

Updates the condition of a component on completion of a CWO, on the basis of CoM requirement. If the CoM is not required for a component work order, the new condition of component is updated to “Overhauled” or “Serviceable” following the completion of the CWO. Conversely, if the requirement of a CoM is set to mandatory, the new condition of the component is updated only after the issue of the CoM based in the following scenario,

The “SOS Program Applicability” in the Common Masters component is set to "Applicable", the “SOS Applicability” in the Component Maintenance component is "All Removals"/"Assessed on Removals", and the “SOS Quarantine Flag” is ”Yes”in the Stock Maintenance component and “SOS Disposition” in Component Replacement is “Suspected Failure” for the part #-serial #,
The system resets the SOS Quarantine Flag as “No” and SOS Disposition as “No Fault Found”. However, the SOS Quarantine Flag becomes “Yes” and SOS Disposition “Unserviceable” for the part #-serial #, if the “SOS Disposition” is “Confirmed Failure” when all the other above-said conditions remain unchanged.

To cancel the CoM

Click the “Cancel” pushbutton, to cancel the CoM for the selected component work order.

Note: The system cancels the CoM for the selected component work order and sets the status of the CoM as ”Cancelled”.
