Warning: That flap cable routing trick cost me 4 hours

I was chasing a flap indication issue on a 737-800 at KATL last Tuesday. Turned out the cable had worn through a clamp because someone routed it wrong during a previous repair. Took me 4 hours just to find the problem, but the fix was only 20 minutes once I saw the rub mark. Has anyone else found hidden chafing that ate up your whole shift?

Four months ago on a CRJ700 at ORD I found brake chafing that took me six hours to track down. The hydraulic line was rubbing against a bracket that was bent like maybe half a millimeter, but it was enough to wear through the outer layer over time. The worst part was the previous log entry said "checked all connections, no issues found" so I kept second guessing myself. Once I finally saw that little metal shaving on the clamp it was like a lightbulb went off... twenty minute fix after all that hunting. I swear sometimes these gremlins are designed to make us earn our pay.
