As said earlier, bolt stretch is a simple concept, easily understood and applied.
However, these are not tractors. These are aircraft. If the procedure is not called for in the OEM maintenance manual, then you do not perform the procedure. If it is, then the AMT performs the procedure. In many cases, an AMT can work on a variety of aircraft in his/her career where bolt stretch is not an approved procedure according to the OEM. That is the point you seem to be missing.
'Nuf said.
