Four percent of the weighting: which nondestructive test fits which material and defect, and how inspection programs such as progressive inspections and the 24-month altimeter and transponder checks work.
Where people lose points
- Penetrant finds only defects open to the surface, on any nonporous material.
- Magnetic particle works only on ferromagnetic parts: steel and iron, never aluminum or titanium.
- Eddy current needs a conductive material and also reveals alloy and heat-treat condition.
- A progressive inspection splits the annual's scope into phases and must be requested from the FSDO in writing.

Questions and answers, explained
All 2 questions above, with the correct answer and why it is correct. Everything here is on inspection concepts and techniques.
Penetrant inspection can detect
Why: The handbook: penetrant inspection is a nondestructive test for defects open to the surface in parts made of any nonporous material, metal or not. The penetrant must actually enter the defect, so subsurface flaws are not detected.
Reference AM.I.K.K3 · FAA-H-8083-30B, Ch. 10 (Penetrant Inspection)
A technician taps lightly across a bonded composite panel with a coin and listens for changes in sound. This test looks for
Why: Tap testing, also called the ring or coin test, is a quick check of accessible surfaces: a sound bond rings sharply, while a delamination or disbond sounds dull. Suspect areas are then mapped or confirmed with instrument methods.
