Pro tip: stop torqueing by feel on hydraulic lines, a guy at the Wichita hangar made me a believer
I used to laugh at the young guys who always reached for the torque wrench, until a lead in Wichita watched me snug a B nut by hand and quietly said the flare was already cracked. Now I keep a crows foot and a 50 inch pound spec sheet within arm's reach, and I haven't had a weeping fitting in 8 months. What's the one shortcut you quit trusting after it bit you?
