Greetings...

This blog is about nondestructive testing (NDT). NDT has other names, i.e., nondestructive inspection, and nondestructive evaluation (NDE - more math based). This blog specifically targets the aerospace sector.

NDT is inspecting a sample (in this case, an aircraft part) from a population (the entire airframe/powerplant) without doing harm to that sample with some form of interpretation of the inspection result.

The strictest (and simplest) form of interpretation is pass/fail - similar to a "go no-go" gauge. Other forms of interpretation include specific military or civilian guidelines depending on the customer of the respective industry.
