oleary,
You've hijacked the thread. bhawkh60 simply said that on the aircraft he has worked on, he has not applied the specific procedure of measuring bolt stretch as a function of measuring proper torque. Nor had I, after years as an AMT.
Had he been assigned to work on a Robinson, he would have seen the written procedure, and followed it in accordance with the manufacturer's specifications. That's what a good A&P does. Get off the tiny soapbox, please.
