Warning: I was cleaning a Cessna 172's fuel tank with a standard brush for years, but switching to a flexible bore scope camera last month let me spot a hairline crack I would have totally missed.

Has anyone else found a specific tool that changed how you do a routine check?

That bit about the hairline crack is wild. I saw a video where a mechanic used a cheap USB inspection camera to check inside wing spars. He found corrosion starting behind a rivet that you'd never see with just a flashlight. It's crazy how a $60 tool can catch a problem that costs thousands later. Makes you rethink just doing the old visual once-over.

That point from @nathanh44 about the USB camera is spot on. Read a forum post from a guy who started using a cheap digital torque adapter. He found out his "calibrated arm" was under-torquing engine mount bolts by a scary amount on his old Piper. Just goes to show, trusting your gut isn't enough when a simple tool gives you hard numbers.
