MANUALS > Engineering > Engineering Module - E/C > Engineering E/C, Update Menu > Engineering Control Selection > Engineering Control > Engineering Control Buttons > P/N CTL Button, via Engineering Control > Engineering Control P/N, General Tab > Positioning Control Button, via Engineering Control P/N, General Tab

The Positioning Control button is designed to specify E/C applicability based on the part's installed position. Select the Positioning Control button to define P/N Positions by Engineering Control. The Positioning Control button is used along with the P/N A/C Configuration. This functionality should contain the same A/C Position information as detailed in the P/N A/C Configuration window for the E/C to effectively apply.

From the Engineering Control P/N window, select the Positioning Control button. Enter the A/C and A/C position information in the A/C Position field.

The following information/options are available in this window:
_____________________________________________________________________________________

E/O

The Engineering Control that specifies aircraft or component scheduled maintenance intervals.

P/N

The Part Number reference for the aircraft part.

A/C Position

The aircraft position reference.

A/C

The individual aircraft tail number.

NHA P/N

The part’s Next Higher Assembly P/N (if applicable).

NLA Position

The position of the Next Lower Assembly.

_____________________________________________________________________________________

Note: If the specified part has a P/N Control, its schedule can be overridden and kept as such, regardless of any transactions that are conducted and/or any updates that are made within the P/N Master, through the Override checkbox, via the P/N Control Authorization.

The status of the installed part will automatically set to 'Open' when installed on the aircraft position specified in both the Engineering Positioning Control and P/N A/C Configuration window, otherwise upon the P/N's installation onto the specified aircraft, the status of the P/N will be set to 'N/A.'

Note: P/N E/Cs that are Position Controlled will be displayed through the Control - E/C Button, via Repair Order Detail and in the Control - E/C Button, via Receiving Inspection Detail even if the P/N E/C's Status for that Serial Number is 'N/A' (which indicates that the S/N is not presently installed in the specified A/C Position). Including position-controlled P/N E/Cs that are 'N/A' in the Control - E/C windows ensure that the necessary controls are reviewed throughout the repair process. To ensure that all position-controlled P/N E/Cs for the part are displayed in this window, Receiving switch PNECPOSCONT must be set to Yes.
