What about this is something that's too complicated to retrofit? Why would they even need to tear into existing wiring harnesses to fix this? Just run another wire through the new pathway isolated from everything else and decommission the old circuit by cutting the ends of the wire and slapping a heat shrink cap over them. Sure, fix the harness on new planes but is there really too much red tape to come up with a safe retrofit plan that doesn't involve messing with the existing harness?
- dreamcompiler 7y ago> Just run another wire through the new pathway That's likely a big part of the problem. Fishing a new wire is generally very difficult, and there are probably rules that say it has to be secured every X meters. Airplanes generally don't use much conduit, so I suspect they'd have to at least partially tear apart the plane to do this right.
