Process Engg Service Request – A summary of the activity
|
|
|
|
This activity allows you to process an Engineering Service Request (ESR). The ESR can be processed by associating it to an existing Engineering Advice Note (EAN). In case the required EAN is not available, you can create a new EAN.
Maintenance programs of the aircraft and its sub-systems are carried out as per approved procedures available in the “Aircraft Maintenance Manual” (AMM), “Component Maintenance Manual”(CMM) or the “Service Bulletins” (SB). The Original Equipment Manufacturer (OEM) or the Local Aviation Authority releases these manuals and bulletins. Deviations from the established norms must have the approval of the concerned engineering cell and in some cases of the regulatory authorities also. The recommendations for these problems or deviations are usually prescribed in the AMM or the CMM or any of the SBs. An ESR is raised to communicate the clarifications required for solving the problems encountered during the maintenance process, to the respective engineering cell. Based on the ESR, an EAN is raised, which provides the recommendations for the clarifications sought.
On receipt of the ESR, the engineering department first checks the existing EANs for similar problems encountered in the past. If an existing EAN can solve the problem stated in the ESR, the request is processed and associated to the EAN. In case the existing EANs are unable to suit the requirement of the ESR, a new EAN is raised. All the EANs contain the ATA references and the aircraft / component effectivity details. Details of the approvals received from regulatory authorities are also available. In case the EAN is rejected due to insufficient recommendations, the EAN is returned to the relevant engineering cell for revision. The system keeps track of the revisions made on the EAN with unique revision numbers.
Pre-closing the ESR
An ESR can be pre-closed after entering appropriate comments. A pre-closed ESR can be processed again if the response has been declined in the “Engineering Service Request” business component. The following could be two such comments for which an ESR can be pre-closed:
When the engineering cell is unable to clarify the request
When a “Technical Circular”, containing the solution to the problem raised in the ESR, has already been published by the engineering department.

What you can do in this activity
The ESR can be pre-closed when the engineering cell is unable to clarify the request, or when a “Technical Circular”, containing the solution to the problem raised in the ESR, has already been published by the engineering department. On pre-closure, the status of the ESR is updated to an interim “Pre-Closed” status.
Go to “Select Engg. Service Request” page.
Click the “Pre-Close Service Request” pushbutton to pre- close the ESR.
You can associate an existing “Released” status engineering advice note to the engineering service request.
Use the “Associate Existing Advice Notes” to associate ESR to EAN.
The “Released” status engineering advice note details can also be viewed.
Use the “View Engg. Advice Note” page to view the details the EAN.
This page allows you to view the reference document details of the EAN. Details such as the type of the reference document, the identification number of the document and remarks pertaining to it are displayed along with the engineering note number, its revision number and its subject.
Use the “View References” page to view the reference document details.
Use the “View Aircraft Effectivity” page to view the aircraft details, if the EAN has been raised for an aircraft.
Use the “View Part Effectivity” page to view the part details, if the EAN has been raised for a component or an engine.
Use the “View Serial # Effectivity” page to view the serial number details of the component or engine
You can view the various engineering service requests (ESR) associated to the engineering advice note.
Use the “View Associated Service Request” page to view the engineering service requests associated to the selected EAN.
You can create a new Engineering Advice Note (EAN) for the ESR.
Use the “Create Advice Note” page to create a new EAN.
You can record the various documents that were referred by the engineering department to clarify the problem. Details of the reference documents such as the AMM, CMM and SBs are entered.
Use the “Reference Details” page to specify the document reference details of the EAN.
You can specify the aircraft effectivity details of the selected EAN. You can also add details of other aircraft models, which can also use the selected EAN.
Use the “Edit Aircraft Effectivity” page to add or modify aircraft effectivity details of the EAN.
You can specify the part effectivity details of the selected EAN, if the EAN has been raised for a component or an engine. You can add details of other part numbers, which can also use the selected EAN.
Use the “Edit Part Effectivity” page to add or modify the part effectivity details of the EAN.
Use the “Edit Serial # Effectivity” page to add or modify the part serial number details for the EAN.
The user who has raised the ESR, can reject the associated EAN, if the recommendations are insufficient to solve the problem. When an EAN is rejected, the engineering cell revises the EAN when a single ESR has been associated to the EAN. The status of the revised EAN is updated to “Fresh”. The revised EAN is released and the status of the original EAN is updated to “Revised” status. An EAN cannot be revised if multiple engineering service requests are associated to it. A unique revision number is generated for every revision.
Use the “Revise Engg Advice Note” page allows you to revise an EAN that has been declined.
