I?m working on the fuel and vent lines in the forward cabin and have run across something interesting. The torque values given in the Aircraft Handbook show 40-65 for -4 and 75-125 for -6 aluminum flared fittings. I am experimenting with the Mechanics? Toolbox program and it shows torque values of -4 (100-140) and -6 (150-195). That?s a big difference, does anyone know why this would be?
