Entering aircraft effectivity for engineering document

This page allows you to specify the aircrafts, for which the engineering change is applicable. Tell me more.

Select the “Edit Aircraft Effectivity” link at the bottom of the “Create Engineering Document” or “Edit Engineering Document” page.

The “Edit Aircraft Effectivity” page appears.

The system displays the following field in the "Eng Doc Details" group box:

Eng. Doc #	The engineering document for which the aircraft effectivity must be defined.
Revision #	The revision number of the engineering document.
Subject	The textual description of the engineering document.

Note: The system displays the details of aircrafts that are already associated to the engineering document number and the revision number combination

Enter the following fields in the “Aircraft Effectivity” multiline, to add or modify the details:

Aircraft Reg #

The aircraft registration number for which the engineering change is applicable (Alphanumeric, 30). Mandatory. The aircraft registration number should have already been defined in the “Create Aircraft Record” activity in the “Aircraft” business component and the status of the aircraft registration number should be “Active”. Ensure that the aircraft registration number is unique in the multiline.

Help facility available.

Variable Tab #	The tab number of the aircraft (Integer). The number entered here must be a valid tab number for the aircraft registration number, defined in the “Create Aircraft Record” activity of the “Aircraft” business component. Help facility available.
Manufacturer Serial #	The serial number of the aircraft manufacturer (Alphanumeric, 40). The number entered here must be a valid serial number for the aircraft registration number, defined in the “Create Aircraft Record” activity of the “Aircraft” business component. Help facility available.
Nose #	The nose number of the aircraft (Alphanumeric, 30). The number entered here must be a valid nose number for the aircraft registration number, defined in the “Create Aircraft Record” activity of the “Aircraft” business component. Help facility available.
Aircraft Model #	The model to which the aircraft belongs (Alphanumeric 20). Ensure that the aircraft model number entered here is defined for the specified aircraft registration number, in the “Aircraft” business component. Help facility available.
Applicability Group #	The number identifying the applicability group based on which the engineering task will be executed. This field cannot be left blank if more than one Applicability Group # exists for the engineering document. Ensure that it is a valid positive integer.

Note: Ensure that at least one aircraft registration number or aircraft model number is entered in the multiline.

Data entry in all the columns of the multiline is mandatory if a value is specified in any of the multiline columns other than aircraft model number.

Values fetched in the multiline cannot be modified.

Check the box in the “Select” column of the multiline to mark the aircraft for deletion.
Click the Delete icon in the tool bar above the multiline, to delete the aircraft selected in the multiline.
The system deletes the aircraft and the configuration details of the aircraft identified in the “Edit Aircraft Configuration Change Information” page. If the aircraft model of the deleted aircraft is not associated to any other aircraft identified in the multiline, the model configuration details identified in the “Edit Model Configuration Change Information” page, are also deleted. In case of a model getting deleted, the system deletes all the task details associated to the model.
If the aircraft record is deleted from the “Aircraft Effectivity” multiline, the system deletes the corresponding details of the aircraft from the “Edit / Terminate Related Work Unit Schedules” page.
Click the “Edit Aircraft Effectivity” pushbutton to update the aircraft effectivity details.

If a new aircraft is added in the multiline, and if you have chosen to update model and part configuration in the “Edit Configuration Change Information” page,

the system checks whether the part specified in the “Existing Part #” field of the “Edit Configuration Change Information” page, exists in the aircraft or model configuration. If exists, the system copies the respective level code, position code, part serial number, NHA and the corresponding new part number against each aircraft or model configuration. If the existing part type is “Piece Part”, the position code details are not copied.

The system updates the following details in the “Plan Material Requirements” page, if a new aircraft is added in the multiline:

If you choose to generate PR automatically for the engineering document, the system copies the maintenance bases of all the newly added aircraft into the “Plan Material Requirements” page.
The required quantity of the part is updated in the “Plan Material Requirements” page as follows:

Reqd. Quantity =

No. Of parts estimated *

No. of maintenance objects maintained in the individual maintenance bases

For example, let us consider a situation where an engineering document requires two numbers each, of Parts P1 and P2, and the engineering document is applicable for 5 aircrafts, where 3 aircrafts are maintained by the “Chicago” maintenance base, and 2 aircrafts are maintained by the “Boston” maintenance base.

In such a case, the Required Quantity for Part P1 in the “Chicago” maintenance base, is calculated as:

Required Quantity = No. of parts * No. of aircraft = 2 * 3 = 6

Similarly, the required quantity is calculated for other parts.

Note: If a new aircraft is added in a new maintenance base, the system copies the parts P1 and P2 into the material plan, with the required quantity as 2 numbers for each part. If the newly added aircraft belongs to an existing maintenance base, the count of aircraft is incremented, for calculating the required quantity.

The system calculates and updates the compliance date for the newly-added entity as the earliest date among the schedule dates computed for the date-based and usage-based work units.

Note: The system ignores the schedule date calculations, if the aircraft model number is specified as Effective for the engineering document.

To proceed, carry out the following:

Select the “View Terminated Engineering Document” link at the bottom of the page to view the terminated engineering document details.
Select the “Edit Task Details” link at the bottom of the page to enter the details of the tasks to be performed during Engineering Document execution.
Select the “Release Eng. Doc.” link at the bottom of the page to release the engineering document.

Entering aircraft effectivity for Engineering Document – An overview

In this page, you can specify the aircrafts, for which the engineering change is applicable. The system displays the details of the aircraft that are already associated to the engineering document and revision number combination. You can add aircraft registration numbers or delete existing details in this page. You can specify the registration number, tab number, serial number of the manufacturer and the tail number of the aircraft:

If existing aircraft details are deleted, the corresponding configuration change details entered in the “Edit Aircraft Configuration Change Information” page are also deleted.

The system updates the aircraft effectivity details and stores the name of the currently logged in user and the server date.
