I thought the new ultrasonic crack detection unit was just a gimmick until it found a 0.3-inch flaw in a Cessna 172 spar cap that my dye pen missed.
Has anyone else had a tool they doubted completely change their inspection routine?

That ultrasonic unit finding a 0.3-inch flaw is wild. I was the same with borescopes, thought they were overkill for quick checks. Now I catch early-stage corrosion in hard-to-see actuator barrels all the time. It totally changed how I do my pre-flights.

Right? Tech like that makes you rethink everything.

Exactly what @blairc90 said. It's amazing how one tool can change your whole routine. You start finding things you would've missed before.

Our old Cessna 172 had hidden spar corrosion.
