Old timer swore torque wrenches are a myth for small hardware - I learned the hard way he was half right

I had this guy Frank, retired 30 year A&P, tell me I was wasting time using a torque wrench on the little interior screws and panels. Said he'd been doing it by feel since the 70s and never had a pulled thread. So I tried his way on a Cessna 172 interior last month in Wichita and ended up snapping three screws and stripping one hole in the side panel. Cost me $45 for replacement parts and an extra 2 hours of labor. Has anyone else gotten bad advice from the old heads that seemed solid until you actually tried it?

Ignoring Frank's advice cost you $45 and two hours, so technically he was half right about it being a waste of time (just not in the way he meant). Man, I love these old timer tales that sound so confident but leave you holding a bag of broken screws. At least you didn't strip out a structural part, I guess that's a win by default. His hands must be calibrated by decades of guesswork, because my 'feel' apparently peaked at 'oops, that's a crack'. Now you get to be the new guy who learned the hard way that torque wrenches aren't just for show (especially on aluminum that gives zero warnings).

So is Frank still insisting his method works after you ate $45 in parts? The thing about those old A&P guys is they worked on planes built with thicker aluminum and beefier hardware than what we see now. Those Cessna interior panels from the 70s had way more meat in the threads compared to the stamped thin stuff coming out of factories today. I've had a similar deal where an old timer swore by using a screwdriver as a pry bar for decades until I watched him crack a baffle seal mount clean in half. Their "feel" was built on hardware that could take way more abuse than what we're dealing with now. It's less about them being wrong and more about the materials changing under their feet and nobody telling them.
