According to the NAMP, personnel must be certified per which chapter for NDI?

The correct response highlights that personnel involved in Non-Destructive Inspection (NDI) must be certified according to Chapter 6 of the Naval Aviation Maintenance Program (NAMP). Chapter 6 focuses specifically on the standards and procedures necessary to ensure that personnel have the required skills and certification to conduct NDI effectively. This chapter outlines the training requirements, certifications, and the overall responsibility for conducting inspections that are critical to maintaining aircraft and equipment safety. Personnel in this field must meet these standards to ensure high-quality inspections, thereby maintaining operational readiness and safety of naval aviation assets.

The other chapters may cover various aspects of maintenance and safety within the NAMP, but they do not specifically address the certification requirements for NDI personnel, which is essential for their capability to effectively perform their duties.
