Technician Applying Liquid Penetrant Dye

Aviation Liquid Penetrant Testing

Applied Technical Services conducts aviation liquid penetrant testing (PT), also known as dye penetrant testing, LPI, and/or FPI to examine aircraft components and identify any potential cracks or discontinuities.
What is Liquid Penetrant Testing?
Aviation liquid penetrant testing is a nondestructive testing method commonly used to identify defects in nonporous aircraft materials such as aluminum and titanium. Liquid penetrant testing starts with our technicians applying a special liquid to the inspection surface, which a process called capillary action then draws into any surface breaking discontinuities. The component under test next undergoes a visual inspection to identify any leaks or surface imperfections. Liquid penetrants typically contain dyes to make any flaws more visible.
