Which statement best describes the IA's role with respect to compliance with manufacturer data?

• A. Verify that all maintenance actions follow the manufacturer’s approved data, manuals, and service information.
• B. Allow deviations from manufacturer data if local conditions demand.
• C. Rely on personal experience rather than manufacturer data.
• D. Accept user-provided data without verification.

Answer: (A)

Compliance with manufacturer data is essential to keep an aircraft airworthy. As an IA, your role is to verify that every maintenance action is performed using the current, approved data provided by the manufacturer—this includes manuals, service information, and any applicable service bulletins or airworthiness directives. This ensures procedures, limits, torque values, inspection criteria, and other critical details are correct and up to date. You shouldn’t approve work based on memory, experience alone, or any data that hasn’t been verified as current and approved. If a deviation is truly necessary, it must be addressed through FAA-approved engineering data or a field approval, not as an informal change. This is why the best approach is to ensure all maintenance actions follow the manufacturer’s approved data, manuals, and service information.
