That time a seasoned inspector showed me the leak check trick I'd been avoiding.

I used to think using soapy water on every single fitting was overkill, like something from the old days that didn't apply to modern aircraft. Then a guy with 30 years at Delta showed me a hairline crack on a fuel line that was invisible until the bubbles showed up. Has anyone else held onto an old habit for years before realizing it was actually the right way?

Thirty years at Delta and he still caught the tiny crack with bubbles. That's like saying you finally learned to use a torque wrench after stripping bolts for two decades. I wasted a whole Saturday chasing a leak on a Cessna 310 once, only to find out it was a pinhole in a weld that soapy water would have spotted in five minutes. Soap and water never lies, even if it makes you feel like a mechanic from the 1950s.

That "soap and water never lies" line hits home. I read something once about a mechanic who swore by it because even factory fresh lines can have microscopic flaws. Makes you realize skipping the basic stuff is just asking for trouble later.
