Yep, this is the manufacturer stepping in and having a say. Amazingly enough, Piper stated that .032 single wrap for turnbuckles on Cubs is what they wanted, so in that case, using .040 is actually incorrect, but acceptable.

A year or two back, I tightened a couple of internal wing turnbuckles. Had to work through a standard inspection hole, which wasn't that well aligned with the turnbuckles. Felt like a proctologist trying write his girlfriend's name inside someone's colon. I did a single wrap here (and brass at that) and check it out every condition inspection.
Lordy, "No Look Twisty Wrist With Bent Elbow And Lifted Shoulder" is in the advanced level of Aircraft Yoga. Anything with safety wire puts it in the Elite.

And yes, at work I name all the odd position stuff with made up yoga moves. It helps explain why sometimes during the day I have to step away from an aircraft, stand up, and walk in little circles while saying the healing mantra of "ow, ow, ow," while rubbing a shoulder, wrist, or other part of my body. It sort of caught on, as my boss was shoulder deep into a Luscome and shouted a Yoga Mantra, proclaiming it was a "Yoga Cramp."

"That's how you know it's working," is the almost automatic response in the shop.

Time to dig into NASM20995, I reckon, and find out what sort of authority it has...
