CAC CAC Quality Assurance and Inspection 1 — Questions and Answers
Question 1: What is the primary purpose of a First Article Inspection (FAI) in acceptance corporation processes?
- To verify that the first production item conforms to all design requirements before full production (Correct answer)
- To inspect only the packaging of the first delivered item
- To audit the supplier's financial records before contract award
- To test the final delivery for warranty compliance
Correct answer: To verify that the first production item conforms to all design requirements before full production
FAI verifies that the first production unit fully conforms to engineering drawings and specifications before authorizing full production runs.
Question 2: Which acceptance criterion type requires a product to meet a specific numerical range rather than a pass/fail threshold?
- Variable acceptance criterion (Correct answer)
- Attribute acceptance criterion
- Defect classification criterion
- Zero-defect criterion
Correct answer: Variable acceptance criterion
Variable acceptance criteria measure characteristics on a continuous scale (e.g., dimensions, weight) as opposed to attribute criteria which are pass/fail.
Question 3: In acceptance testing, what does AQL (Acceptable Quality Level) define?
- The maximum percent of defective units considered acceptable in a sampling plan (Correct answer)
- The minimum number of inspectors required on a production floor
- The quality of materials used in manufacturing
- The audit frequency for ISO certification
Correct answer: The maximum percent of defective units considered acceptable in a sampling plan
AQL defines the worst acceptable average quality level—the maximum percentage of defects that is still considered satisfactory for acceptance.
Question 4: What type of inspection examines a product's internal structure without disassembly or damage?
- Non-destructive testing (NDT) (Correct answer)
- Destructive testing
- Functional testing
- Endurance testing
Correct answer: Non-destructive testing (NDT)
NDT methods such as X-ray, ultrasound, and dye penetrant inspection evaluate internal integrity without harming the product.
Question 5: A CAC professional identifies a critical defect during inspection. What is the correct immediate action?
- Quarantine the item and notify the responsible parties before any further processing (Correct answer)
- Continue processing and document the defect on the final report
- Return the item to the supplier without documentation
- Allow the defect if it is below the AQL threshold
Correct answer: Quarantine the item and notify the responsible parties before any further processing
Critical defects require immediate quarantine and notification to prevent nonconforming items from advancing in the supply chain.
Question 6: Which document serves as the baseline reference for determining acceptance or rejection during product inspection?
- Engineering drawing or product specification (Correct answer)
- Shipping manifest
- Purchase order only
- Supplier's quality manual
Correct answer: Engineering drawing or product specification
Engineering drawings and product specifications are the authoritative reference documents that define all dimensional, functional, and material requirements.
