The NDI method and procedure to be used for any specific part or component will generally be specified
in the aircraft or component _____________________. - answer✔Maintenance/Overhaul Manual
Making the correct NDI method selection requires an understanding of the basic principles, limitations,
and advantages and disadvantages of the available NDI methods and an understanding of their
comparative effectiveness and cost. - answer✔Appropriate Method
"(1) The critical nature of the component;
(2) The material, size, shape, and weight of the part;
(3) The type of defect sought;
(4) Maximum acceptable defect limits in size and distribution;
(5) Possible locations and orientations of defects;
(7) The number of parts to be inspected. " - answer✔Other Factors
The various materials used in NDI may contain chemicals, that if improperly used, can be hazardous to
the health and safety of operators and the safety of the environment, aircraft, and engines. Information
on safe handling of materials is provided in __________. - answer✔Material Safety Data Sheet
The degree of inspection sensitivity required is an important factor in selecting the NDI method. Critical
parts that cannot withstand small defects and could cause catastrophic failure require the use of the
more sensitive NDI methods. Less critical parts and general hardware generally require less-sensitive
NDI methods. - answer✔Degree of Inspection
used to detect visible flaws such as deformation, welding defects and corrosion. Many tools can be used
during the inspection such as a borescope, gauges, cameras, etc. - answer✔Visual Inspection
a widely applied and low-cost inspection method used to check surface-breaking defects in all non-
porous materials. - answer✔Penetrant Inspection
The method involves gently tapping the part with a special tap hammer or even a coin, highly dependant
on the skill and experience of the inspector. - answer✔Tap Testing
technique that detects and monitors the release of ultrasonic stress waves from localised sources when
a material deforms under stress. - answer✔Acoustic Emission
method which uses either x-rays or gamma rays to examine the internal structure of manufactured
components identifying any flaws or defects. - answer✔Radiography
for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron,
nickel, cobalt, and some of their alloys. - answer✔Magnetic Particle Inspection
takes advantage of high frequency sound waves to analyze inconsistencies within materials -
answer✔Ultrasonic Inspection
use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive
materials - answer✔Eddy Current Inspection

An attack resulting from a direct exposure of a bare surface to caustic liquid or gaseous agents -
answer✔Direct Chemical Attack/Chemical Corrosion
Changes are occurring simultaneously at the same point. - answer✔Direct Chemical Attack/Chemical
Corrosion
The reaction in this corrosive attack requires a medium, usually water, which is capable of conducting a
tiny current of electricity. - answer✔Electrochemical Attack
