ANNUAL INSPECTIONS
INDEPTH INSPECTION
QUALIFIED GVI & NDI PERSONNEL
GENERAL VISUAL INSPECTORS
NDI SPECIALIST
GENERAL VISUAL INSPECTOR
-Are highly qualified individuals who use their vision with or without optical aids.
-To make judgments about the condition of aircraft and aircraft
components being inspected
NDI SPECIALISTS
-Are trained to perform technical procedures and to use sophisticated
imaging devices and equipment necessary for conducting a variety of
procedures
-The major difference between these workers
general visual inspectors normally inspect the assembled (or partially assembled) aircraft,
-While NDI/NDT specialists tend to focus on the aircraft’s individual components.
NON-DESTRUCTIVE TESTING
-Is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage

NON-DESTRUCTIVE TESTING
TYPES OF NON-DESTRUCTIVE EVALUATION TECHNIQUES
- VISUAL/OPTICAL INSPECTION
- LIQUID DYE PENETRANT
- MAGNETIC PARTICLE
- EDDY CURRENT
- X-RAY RADIOGRAPHY
- ULTRASONIC
- Is probably the most widely used of all the nondestructive tests.
- Most basic and common inspection meth
VISUAL INSPECTION
-Is a widely applied and low-cost inspection method used to
locate surface-breaking defects in all nonporous materials
(metals, plastics, or ceramics)
LIQUID DYE PENETRANT TESTING
-is a non-destructive testing (NDT) process for detecting
surface and shallow subsurface discontinuities in
ferromagnetic materials such as iron, nickel, cobalt, and
some of their alloy
MAGNETIC PARTICLE TESTING
one of many electromagnetic testing methods used in
nondestructive testing (NDT) making use of electromagnetic
induction to detect and characterize surface and sub-surface
flaws in conductive material
EDDY CURRENT TESTING
X-RAY RADIOGRAPHY TESTING
-Is an NDI method used to inspect material and
components, using the concept of differential
adsorption of penetrating radiation
-Is an NDI method used to inspect material and
components, using the concept of differential
adsorption of penetrating radiati
