Who reviews Maintenance Instructions (MI)?

• A. QA only
• B. QA and the Maintenance Officer
• C. Maintenance Officer only
• D. Quality Inspector

Answer: (B)

Maintenance Instructions are reviewed by both Quality Assurance and the Maintenance Officer. QA checks that the instruction meets quality standards, safety requirements, and established procedures, catching errors, ambiguities, or steps that could introduce risk. The Maintenance Officer ensures the instruction reflects the current aircraft configuration, maintenance plan, available resources, and scheduling, so it’s practical, up-to-date, and aligned with how the maintenance program will be executed. Together, they ensure the MI is accurate, complete, safe, and actionable before use. Relying on QA alone could miss operational feasibility, while MO alone could miss quality or compliance issues; a Quality Inspector is part of QA, but the combined review by QA and the Maintenance Officer covers both quality and operational applicability.
