I have a question for the A&Ps on the list:  Do you think it's ok for us to calibrate our own cable gauge provided that we make some effort to have our test weights traceable to some standard and maintain paperwork to the standards required for repair stations?  I'm obviously referring to the certificated side of our life. If anyone is nice enough to respond, lets talk off list.  This forum sometimes frightens me 

 

 Cheers,

 Bill

Usually the tensiometer  will have a calibration strip with which to check for correct operation but if you mean pulling the whole thing apart then no.You can also set up a cable with a bucket hanging from it and filled to a specific weight to test your gauge. Hope this helps

When I spoke with the DAR that will be inspecting my plane for the AW certificate he said that he will be asking for two things (and aircraft log book entries to back them up) regarding cable tension.



1. That cables have been tensioned to design specs and what those specs are.



2. That the device used to check the cable tension was properly calibrated according to the instructions that came with the tension measuring device.



I specifically asked about people that build their own meter. He said they need to write calibration instructions for it as well.

just hang 30lbs of stuff off the tensionometer, then take a photo or something to show it was calibrated.
