Remember, torque wrenches are precision measurement tools, and as such require periodic calibration. In certificated operation, 24 months is limit. How do wrenches get out of tolerance? Usage, dropping, usage, dropping, etc. Like the rest of us, they wear out.

The torque wrench I have for the small stuff is a Snap-On. I have two actually. One is for really small stuff, 10 to 50 in/lb. The other goes from, I think, 40 to 250 in/lb.

Joe, Could you post "AC 43.13". I would like to see it.

Another place to look for small torque wrenches is gun smith supplies. For AN3 and smaller, I have a small one that looks like a fat screw diver, very good for small places, and quick and easy to use. Be sure to check calibration. If no other known accurate wrench available, use a simple torque arm and weight.

Google can find it for you. You want to download the hardware chapter. It is an FAA document.

Here is a video of how I calibrate a torque wrench... https://youtu.be/jdhFqpLJKT8

This was a presentation made at one of the Midwest Sonex Fly-in's several years ago.
