On MRCs, the letters 'QA' indicate tasks that require witness by which roles?

• A. Quality Assurance representative (QAR) or Collateral Duty Inspector (CDI)
• B. Pilot or Co-pilot
• C. Ground Crew Supervisor
• D. Manufacturing Engineer

Answer: (A)

The important idea here is that certain maintenance tasks require an independent verification to confirm everything was done exactly as procedures dictate. On MRCs, when you see the QA tag, it means a witness is needed from a Quality Assurance representative or a Collateral Duty Inspector. The Quality Assurance representative ensures the work meets all quality standards and that the documentation is accurate. A Collateral Duty Inspector is a trained in-field inspector assigned to observe and sign off specific maintenance tasks, providing that independent check. Other roles like pilots or co-pilots aren’t responsible for witnessing maintenance work, and a ground crew supervisor or a manufacturing engineer aren’t designated witnesses for QA-tagged tasks. So the QA-witness requirement specifically points to a Quality Assurance representative or a Collateral Duty Inspector.
