What is a key consideration regarding approved data when performing a modification review?

• A. The modification must be per approved data and verified installation and testing.
• B. The modification may be installed using any data the technician believes is appropriate.
• C. The modification must be approved by the pilot.
• D. The modification can be installed without data if time is critical.

Answer: (B)

When reviewing a modification, the most important factor is that you perform the work strictly according to approved data and verify the installation and testing. Approved data provides the exact methods, materials, locations, torque values, wiring, and testing criteria needed to ensure the modification keeps the aircraft airworthy. Relying on data that a technician personally believes is appropriate hasn’t been reviewed or authorized and can lead to incorrect installation, improper performance, or safety issues. Using any data the technician thinks is right is not acceptable because it bypasses the regulatory oversight that ensures the modification is properly designed and tested. A pilot’s approval does not replace the need for approved data, and emergency or time-critical situations do not waive the requirement to use data that has been approved for the modification.
