What is the advantage of using N.D.T. on turbine engines?

• A. They increase engine power
• B. They reduce engine weight
• C. They can avert costly unscheduled maintenance as a result of failures due to fatigue and wear
• D. They eliminate all wear

Answer: (C)

Non-destructive testing lets you inspect turbine engine parts for hidden flaws without taking the parts apart or destroying them. In an engine, fatigue cracks, corrosion, and wear indicators can develop in blades, disks, shafts, and housings. Detecting these issues early means you can plan repairs or replacements before a failure occurs, preventing unscheduled maintenance and the costly consequences that come from fatigue- or wear-related failures.

NDT does not increase engine power or reduce weight, and it does not eliminate wear—wear continues during operation. It simply helps manage wear by catching problems early so maintenance can be performed before failures happen.
