| In the aerospace industry, NDT can make the difference between life and death. Aircraft components are inspected before they are assembled into the aircraft and then they are periodically inspected throughout their service stage. |
| Common Inspected components: |
Fatigue cracking and corrosion are the most common defects occurring in the service stage of an aircraft.
|
The following NDT methods are commonly used in Aircraft inspection:
Over 80 percent of the inspections done to an aircraft are visual inspections. At regular intervals inspectors look at various component of the aircraft for signs of damage.
Eddy current and ultrasonic inspection methods are used extensively to locate tiny cracks that would otherwise be undetectable. These techniques are also used to measure the thickness of the aircraft skin from the outside and detect metal thinning from corrosion on the inside surface of the skin.
Radiography X-ray techniques are used to find defects buried deep within the structure and to locate areas were water has penetrated into certain structure.
