Practice
The success of any NDI (NDT) method and procedure depends on the knowledge, skill, and
experience of the NDI (NDT) personnel involved. - ANS ✔✔T
Anyone can detect and interpret indications using eddy current, x-ray, or ultrasound equipment
as long as they know how to operate the machines involved. - ANS ✔✔F
The lack of visible defects during a visual inspection means further inspection is unnecessary. -
ANS ✔✔F
Borescopes are used in aircraft and engine maintenance programs to reduce or eliminate the
need for costly teardowns. - ANS ✔✔T
Penetrant inspection is an NDT method suitable for defects open to the surface of parts made of
any nonporous material. - ANS ✔✔T
Dye Penetrant inspection is Portable and Inexpensive but is not sensitive to very small
discontinuities - ANS ✔✔F
Two types of Dye used with Dye Pen inspection are visible and fluorescent. - ANS ✔✔T
Dye Penetrant: The smaller the defect, the shorter the penetrating time (Dwell Time). - ANS
✔✔F
Dye Penetrant: The size of the indication can show the extent of a defect and the brilliance is a
measure of its depth. - ANS ✔✔T
