CAT Quality Assurance and Inspection 2 — Questions and Answers
Question 1: What is the purpose of a Root Cause Analysis (RCA) following a maintenance quality escape?
- To identify the underlying cause of a defect or error so that corrective actions can prevent recurrence (Correct answer)
- To assign blame to the responsible technician
- To calculate the financial cost of the quality escape
- To remove the affected aircraft from service permanently
Correct answer: To identify the underlying cause of a defect or error so that corrective actions can prevent recurrence
RCA systematically investigates the true root cause of a quality escape beyond the immediate symptom, enabling corrective and preventive actions (CAPAs) that address the systemic issue.
Question 2: What does 'shelf life' mean for an aircraft part or material?
- The maximum storage time after which a part or material may no longer be considered airworthy or usable (Correct answer)
- The minimum time a part must be stored before installation
- The number of flight cycles a part is rated for
- The time between required overhauls
Correct answer: The maximum storage time after which a part or material may no longer be considered airworthy or usable
Shelf life defines the maximum period a part, material, or consumable (such as O-rings, sealants, or batteries) can be stored while still considered airworthy and fit for installation.
Question 3: What is the significance of an FAA Form 8130-3 'Authorized Release Certificate'?
- It documents that an aircraft part was approved for return to service or manufactured under FAA authority (Correct answer)
- It authorizes a technician to perform engine runups
- It certifies a repair station's annual inspection
- It records fuel uplift quantities
Correct answer: It documents that an aircraft part was approved for return to service or manufactured under FAA authority
FAA Form 8130-3 is the standard airworthiness approval tag that accompanies parts, certifying they were produced under FAA authority or approved for return to service after maintenance.
Question 4: What is 'human factors' in the context of aviation maintenance quality?
- The study of how human capabilities, limitations, and behaviors affect maintenance safety and performance (Correct answer)
- The ergonomic design of aircraft maintenance tools
- Personnel scheduling and shift management
- The cost of human labor in aircraft maintenance
Correct answer: The study of how human capabilities, limitations, and behaviors affect maintenance safety and performance
Human factors in maintenance examines how fatigue, communication, stress, complacency, and situational awareness affect technician performance and contribute to maintenance errors.
Question 5: What is the purpose of an audit in a maintenance quality system?
- To systematically examine processes and records to verify compliance with regulations, procedures, and quality standards (Correct answer)
- To inspect every aircraft in the maintenance facility
- To review technician wage rates
- To approve new maintenance procedures
Correct answer: To systematically examine processes and records to verify compliance with regulations, procedures, and quality standards
Audits provide objective evidence of whether maintenance operations comply with applicable regulations, approved data, and internal procedures, identifying gaps before they lead to safety issues.
Question 6: What must be documented when a non-conformance is discovered during aircraft component inspection?
- The part identity, nature of the defect, disposition decision, and corrective action in a formal non-conformance report (Correct answer)
- Only the part number and the technician's initials
- The inspection date and shift supervisor name only
- The cost estimate for repair
Correct answer: The part identity, nature of the defect, disposition decision, and corrective action in a formal non-conformance report
Non-conformance reports must fully document the affected part, the nature and extent of the defect, the disposition (use-as-is, repair, scrap), and corrective actions to prevent recurrence.
