Our Company is committed to ensuring that all working conditions in its business operations are safe, that workers are treated with respect and dignity, and that customers receive the right parts at the right time, without compromising quality or cost. Suppliers are expected, in all their activities, to maintain high ethical standards, acting with integrity, trust, respect, honesty and teamwork and to operate in full compliance with applicable laws, rules and regulations of the countries in which they operate.


To define the minimum requirements for a supplier providing material or services to American Precision Assemblers, Inc.


As required.



  1. All suppliers and sub-tier suppliers shall maintain a quality management system certified to an appropriate standard to their business. Aerospace product distributors are required to be AS9120 certified.
  2. Suppliers are expected to acknowledge receipt of each APA PO within 24 hours.
  3. Suppliers are also expected to provide competitive pricing & timely response to requests from APA, Quality, Engineering or Procurement representatives.
  4. Expectations are that 100% Quality and Delivery performance is maintained. Suppliers not meeting our expectations or with an undesirable PPM metric will be issued a supplier corrective action, which may include a report to the end customer during regular business reviews.
  5. If a supplier is issued a Corrective Action Request by APA immediate containment of the discrepancy is expected to prevent further erroneous shipments. Investigation, root cause determination, and a corrective action plan (response to APA) is expected to occur within 10 working days unless requested otherwise. Permanent action is expected to occur within 30 days. Preventive action, where appropriate, is expected to occur within 3 months.
  6. Process control and training system shall be appropriate to maintain product conformity.
  7. When there are Key Characteristics on a drawing, it may be required for those dimensions to have a 30-pc capability study/data submitted prior to approval. (Key Characteristics are the features of a material or part whose variation has a significant influence on product form, fit, performance function, service life, or manufacturability as identified by APA, our customer or identified by the supplier.)
  8. Unless using certified tooling, a minimum required inspection for parts shall comply with level II, C=0 per ANSI/ASQ Z1.4, and comply with “0” defects equal accept, one defect equals rejection of the entire lot. If a rejection, one hundred percent of the lot must be inspectedfor the characteristic found not meeting the requirements.
  9. If special processes (where resulting output cannot be verified by subsequent monitoring or measurement) are required, Supplier shall establish appropriate procedures, process controls, equipment, personnel training, and records to demonstrate control. APA may specify special process providers when required by our end customers.
  10. Suppliers shall package parts appropriately to protect against damage to internal or external features, especially cosmetic items. This includes moisture protection where applicable.
  11. The supplier is to provide Material Safety Data Sheets with each shipment, as applicable. Items with a shelf life shall be clearly marked and shall have no less than 50% of their shelf life remaining.
  12. Suppliers for Custom or make print parts shall complete and submit an acceptable final inspection report with each Purchase Order.


Subcontractors are expected to ship product following FIFO (first into stock is the first out) order.

Lot code assignment for product of the same top level PN shall not duplicate.

Subcontractors that are provided with APA generated documentation, test programs and tooling are expected to maintain revision and quality controls on these items. Subcontractors are expected to provide and inform APA of any changes required to these items.

Subcontractors are required to provide Production records for every lot to APA.


Manufacturers of parts represented by an engineering drawing shall complete/submit an acceptable First Article Inspection Report, from production ready equipment (NOT from prototypetooling). FAIR data includes all drawing notes, dimensional characteristics, material, and functionality requirements, if applicable. It shall be completed in accordance with the AS9102, or applicable standard.

A FAIR is required for any of the following situations.

  • Manufacturing a production or conforming part for the first time.
  • A change in the design or configuration of the part.
  • When the line or location of production changes.
  • After a production lapse of 2 years or more.


Suppliers shall notify APA immediately If supplier becomes aware of released product that was nonconforming.

Supplier shall provide written notification to APA when any of the following occur.

  • Intent to relocate production, manufacturing, repair or overhaul of parts and assemblies.
  • Physical movement of critical manufacturing or inspection equipment which could affect production or inspection capability.
  • Changes in the supply chain that affect the point of manufacture.
