Approved Special Processor Listings

Supplier Quality (SQ) from Northrop Grumman Aeronautics Systems Sector (NGAS), Northrop Grumman Defense Systems Sector (NGDS), Northrop Grumman Mission Systems Sector (NGMS), and Northrop Grumman Space Systems Sector (NGSP) maintain an "Approved Special Processor List" (ASPL) for all NGC programs. This list can be sorted by Sector, Supplier Name, Supplier Number, Country, or Process Specifications and Process Categories.

How to use the ASPL and the enclosed information is bulleted below:

1. Users must first download the file below and select the specific Sector ASPL they are searching within (i.e. Aeronautics Systems, Defense Systems, Mission Systems, or Space Systems). If you are unsure which ASPL to search please verify with your NG Buyer.
2. All columns of the spreadsheet can be filtered for your needs. Ensure that you first filter on Sector, then Division, then program if applicable. Next you can search by any other criteria that is available within the spreadsheet.
3. At the top right hand side of this site are "Helpful Links". See Below for 4 specific ones.
   • First two links are to Boeing's 'D1-4426' ASPL and Lockheed's 'QCS-001' ASPL.
   • Third link is a "Change Log" that shows when processors are added or removed, or when specifications are added or removed from the processors or the ASPL.
   • Fourth link provides instructions for accessing NDT technique approvals by, "Processor and by Part Number".

NGAS Suppliers: For Suppliers working with the Aeronautics Sector (AS), a list of Controlled Processes requiring NG Approval is included in the downloadable spreadsheet. Please review that list prior to confirming whether a Specification requires NG Approval.
