  2. Procurement Process Flow

  3. Manufacturing Requirements • Drawings and specifications must be released • Parts and materials must be listed on PIL and must be approved by PCB or MPRB as appropriate • All parts and materials must be issued from flight stores • Completed flight assemblies must be kept in flight stores • Work must be authorized via an approved Assembly and Inspection Data Sheet (AIDS)

  4. Manufacturing Process • Closed loop • Parts and materials issued in kits from stores • Kit is assembled, tested, and inspected • Delivery of assembled kit to stores closes the loop • Maintains clear traceability of parts, materials, and finished flight items • Approved AIDS is required to start the process • Applies to fabrication, assembly, test, and inspection • Does not apply to fabrication where supplier procures raw materials • If work is to be performed by a subcontractor, their travelers should be attached, or PO should require supplier to make them available for review by SLAC and Government personnel

  5. Manufacturing Process - Continued • Stock room verifies item is ready for manufacturing prior to pulling kit • Drawings and/or specifications released • Test procedures released • Parts approved • Completed AIDS ends the process • Last step is to deliver to stores

  6. Assembly and Inspection Data Sheets • AIDSs are LAT work orders • Authorize taking parts and materials out of stores and performing work to manufacture flight hardware • Defines operations executed to fabricate, assemble, and test LAT hardware items • Provide traceability from raw materials to finished flight items • Required for all LAT manufacturing activities including outside fabrication and assembly • LAT-MD-01624 • AIDS preparation instructions • Provides some guidelines on work instruction preparation • Accessed from Quality Assurance web page
