The “Record Parameter Reading / Conditional Evaluation Form” page appears.

The system displays the following field:

Date & Time Format

The format in which the date and time fields must be entered. 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.

The system displays the following details in the “Execution Details” group box:

Exe. Doc. Type / Ref #

The execution document type / execution document reference number. The system displays the following:

Package Type / document number, if the Execution Document Type is Aircraft Maintenance Execution Document (AME) or Shop Work Order (SWO).
“Hangar Work Order” / document number, if the Execution Document Type is Hangar Work Order (HWO).

Work Center #

The work center associated to the package or work order. The Work Center is defined at package level for AME / SWO and at Task level for HWO.

Tree Interface

The system displays a tree structure in the left pane. The tree will have the ‘Execution Doc. #’ as the parent node (level). All the nodes of the tree are displayed in an exploded form. The various nodes displayed in the tree are as follows:

First (Parent) node: Execution Doc. #: The package, shop work order or the hangar work order against which the tasks are performed on an aircraft / engine.

Second node: Task # which have parameter requirements defined at task and / or at sub-task levels..

Third node:

Parameter(s) mapped for the task (Parameters are listed in the same order as defined for the task in the “Edit Parameter Reading / Eval. Form' page of the “Maintenance Task'” business component).
Sub Task Description which has parameter requirements. This is displayed in an order as per the Sub Task Seq #.

Fourth Node: Parameter mapped at each of the sub task level (Parameters are listed in the same order as defined for the task in the “Edit Parameter Reading / Eval. Form” page of the “Maintenance Task” business component).

For the parameter with and without conditional evaluation requirements, the nodes are represented with different symbols as shown below:

- Indicates that the parameter has evaluation details defined for the task or sub tasks in the “Maintenance Task” business component.

- Indicates that the parameter does not have evaluation details defined for the task or sub tasks in the “Maintenance Task” business component.

Parameter Node with and without Value / Eval. Response:

When the parameter information is displayed in the tree interface, if the 'Value/ Eval. Response' is already defined for that parameter, the saved 'Value / Eval. Response' value is displayed along with the parameter, concatenated by "::", in ‘Bold Blue’ font. If the 'Value/ Eval. Response' is not defined for the parameter, the parameter node is displayed in ‘Bold Red’ font.

Example:

If the ‘Exec. Doc #’ is HVY-003482-2010, ‘Task #’ is 53A0051-HFEC, ‘Sub Task Desc.’ is “Inspection of Crack Length” and ‘Parameter’ is “Length”. The tree structure is displayed as follows:

Without Value / Eval. Response:

HVY-003482-2010

53A0051-HFEC

Inspection of Crack Length

Length

With Value / Eval. Response:

HVY-003482-2010

53A0051-HFEC

Inspection of Crack Length

Length :: 5mm

Parameter reading / conditional evaluation details:

Recording parameter details and conditional evaluation details for the task - An overview

Engineering Change Management is a very critical and essential part of Aircraft Maintenance. Most of the engineering changes are very complex in nature and often needs lot of evaluation and follow-up. Consequentially, it is vital that the information systems employed, guide other related functions viz., Maintenance Planning & Production control, through various steps they need to take for effective completion of engineering change initiated, thus ensuring seamless information flow for effective decision making.

A task can have multiple types of relationships established with other tasks, to address maintenance planning, maintenance execution and compliance management requirements. This interface would guide the planner or mechanic through various next steps that they need to take, based on pre-configured follow-up actions.

While reporting work actual; mechanic will be able to review the parameter conditions identified by accessing the link ‘Record Parameter Reading / Conditional Eval. Form’. Also mechanic will be able enter the actual reading. On completion of primary task, the system will execute as per ‘Follow-Up action’ set if the parameter updated value matches with the standard value provided while authoring the task. Moreover while authoring task, if the parameter recording option is as mandatory, the system will enforce the mechanic to visit this page and update the value.

Prerequisite

Parameters must be defined for the tasks and the sub tasks in the “Edit Parameter Reading / Eval. Form” page of the “Maintenance Task” business component.
