The system assigns “Fresh” status to engineering document.
Note: The system assigns “Fresh” status to engineering document. Note: This action is workflow-enabled. Notification messages can be sent as per the settings you have defined in the "Workflow Management" business component.
The system performs the following:
The system updates the periodicity details to the engineering document as defined in the “Maintenance Change Request” business component.
The system calculates and updates the compliance date as the earliest date among the schedule dates computed for the date based and usage based work units. How the system calculates the scheduled date.
The system calculates the schedule date based on the parameter values in the usage information and in the date based information. The system considers the earliest of all the schedule dates calculated as the schedule date for the aircraft, and the parameter through which this earliest schedule date is arrived is stored as the Triggering Parameter.
For the newly added entities like Aircraft/Component/Engine, the Schedule Date is to be calculated as mentioned below:
For date-based schedule, the system calculates the Earliest Schedule Date as: Schedule Date = Issue Date of the MCR + Threshold Interval, if threshold Interval is available. Otherwise, the system calculates the schedule date as: Schedule Date = Engineering Document Created Date + Threshold Interval.
For usage-based schedule, the system calculates the Earliest Schedule Date as: Earliest Schedule Date = Current Server Date + ((Threshold Value - Current Value)/ Utilization Value), or Earliest Schedule Date = ((Date + (Threshold Interval / Average Value)).
The system compares the earliest schedule dates calculated for both the Date-Based Schedule and Usage-Based Schedule. The earliest date among both is considered to be the Compliance Date.
The system ignores the Schedule Date calculations described above if the Aircraft Model # alone is effective for the Engineering Document
Updates the schedule date and triggering parameter for the work units, based on the date and/or time based schedules defined for the work units. If the schedule date is calculated based on the usage based schedules, then the system considers the threshold value / threshold interval.
The system updates the calculated schedule date and the triggering parameter in the central planning / component pending tray, if the engineering document is marked for “Direct Execution”.
If you have chosen automatic generation of the engineering document number, the system generates the number with the prefix and suffix of the numbering type selected. The number is incremented from the last number available in the "Engineering Document" business component.
For the change request, revision number and applicability group number combination, the system copies the general details, effectivity details, concurrent requirement, references, publication affected, task, configuration change, resource, kit, kits composition, periodicity details. The system also copies the details defined at the document level (change request and revision number combination).
If the change doc type is “MCR”, the details are copied from the “Maintenance Change Request” business component. If the change doc type is “FCD”, the details are copied from the MCR from which the FCD is created. The task details, resource and tooling details and kit details of the aircraft models for which the engineering document is applicable is also copied.
If the part identifier is “Internal”, the part number details are copied, if they exist in the “Part Administration” business component. If the part identifier is “Supplier”, the system copies all the part numbers whose ‘Other Part Numbers’ are identified as ‘existing part nos’ in MCR configuration change details. For a given other part number, if more than one internal part number exists, the system copies the first part number.

Creating change request based engineering document – An overview
This page enables you to create an engineering document based on a change request. A unique number identifies the engineering document. Based on the option settings, the system either generates the engineering document number automatically, or enables you to enter it manually. To generate the number automatically, you must specify the numbering type in this page.
You can specify the category to which the engineering document belongs, user status, description and the ATA chapter to indicate the system on which the engineering change has to be performed.
You can specify whether the engineering document is applicable for the aircraft, component or engine, and the priority and the type of the engineering document. You can indicate whether the engineering document should be performed on one-time or recurring basis.
The execution details of the engineering document, such as the work center in which the engineering document has to be performed, estimated time and man-hours required for the execution of the engineering document, must be defined.
You can also indicate whether,
the engineering change has to be performed in the original place of the part
follow-up action is required after executing the engineering document
work order must be created directly from engineering document
purchase request must be generated for the parts required for executing the engineering document.
You can record the change in weight, moment and the electrical load after executing the engineering document. The system displays the details of the MCM and FCD, as reference information.
The system assigns the “Fresh” status as soon as the engineering document is created, and sets the creation date and time to the server date and time. The system also copies the task details, effectivity, concurrent requirement, reference details, publications affected, configuration changes, and periodicity details from the change request.
Note: If approval requirements are specified in the “Set Authorization Rules” activity, for the combination of the change document type and the source document type of the engineering document, the system sets the “Authorization Status” of the engineering document as “Pending in the "Edit engineering document" activity. Otherwise, the “Authorization Status” is set as “Authorization Not Required”.
