A close up look at NDI
Airman 1st Class David Frias, a 49th Maintenance Squadron non-destructive inspection technician, inspects a metal part for damage at Holloman Air Force Base, N.M. on Feb. 22. Frias used a low-viscosity penetrant, which fills any voids left by cracks or damage, and indicates a need for repair. After the penetrant is applied, it creates a visible indication of damage. The NDI technicians are able to assist aircraft maintainers by identifying even the smallest amount of damage to aircraft parts in a non-destructive manner, allowing them to ensure military aviation equipment safety.
