Subject: KR> torque wrench I purchased one of these http://www.homedepot.com/p/Powerbuilt-1-2-in-Drive-Digital-Torque-Adapter-940962/203117027# to verify my torque wrench is in calibration when I start engine assembly in the next few days.
That begs the question: Who calibrates the calibrator, who inspects the inspector, and who answers questions for the answer man? Just wondering........... Larry Flesner ------------------ I have one of those gizmos in my tool box to check against the torque settings on my torque wrenches. It should have come with a calibration certificate. I bought one because I was convinced my 1/2 drive torque wrench was way out of spec and wanted to verify it. Turned out that it and the torque load cell were in agreement. Generally speaking the load cells don't really tend to drift much. However, the FAA's view for maintenance technicians is that our torque wrenches need to be calibrated by a certified calibration Lab annually if they are going to be used on certificated aircraft. For Experimental Amateur Built Aircraft, there are no requirements. Reminds me of once when I did a 2 day free W&B clinic in my hangar. The FSDO guys cautioned me that unless I had a current calibration certificate on the scales, even though they were correct, I was not allowed to issue a new W&B for a certificated aircraft. I could only give them a copy of the W&B as an advisory. When I asked about Experimentals, they laughed and said anything I did was likely to be an improvement since most of them were weighed on bathroom scales anyway. -Jeff Scott Los Alamos, NM _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
