Which FAA publication describes methods of nondestructive testing?

• A. AC 43-3 Nondestructive Testing in Aircraft Handbook
• B. AC 21-2 Shipper and Receiver Procedures
• C. AC 43-3 Nondestructive Testing in Aircraft
• D. AC 90-1 General Aviation Safety Standards

Answer: (C)

Nondestructive testing methods in aviation are described in a dedicated FAA advisory circular that focuses on how these techniques are applied to aircraft. This publication provides guidance on the common NDT methods used in maintenance—such as penetrant, magnetic particle, radiographic, ultrasonic, and eddy current tests—along with the indications, limitations, and general acceptance criteria for inspecting aircraft components. It’s the specific resource that lays out how these tests are performed, what results mean, and the safety considerations involved. The other items cover topics unrelated to NDT (shipper procedures, general aviation safety standards) or refer to a version with a title that is not the official AC for nondestructive testing, so the publication that describes the methods is the one titled Nondestructive Testing in Aircraft.
