Shoutout to the old tech who caught my harness mistake
I spent about two years working on LRU swaps and thought I had the cable routing down perfect. Everything looked clean and zip tied tight. Then last month a senior tech with 30 years in pulled me aside on a CRJ-200 tail compartment job. He pointed at a bundle I had running across a hydraulic line and just said "that's gonna chafe through in 18 months." I felt stupid because I never even thought about vibration wear over time. He showed me how he runs all his bundles a half inch away from any metal or lines. Now I redo every one I've touched from the past year. Anyone else have a basic habit they learned way later than they should have?
