Do the control cables, ie, prop and alt air, on the -14 need to go through the fire sleeve on the firewall with the wires?
Do not run wires in the same "conduit" or through the same holes as fuel lines or control cables.
Wiring, fuel lines, and control cables each need their own individual conduit and/or pass throughs.
The plans have control cables and wiring going through same firewall passageway.
Regardless of what the plans say, this is NOT good practice. Cables can and do "move". This movement can easily chafe through wiring insulation.
Some plans also say to run ELT antenna cable through bulkheads; It is still NOT good practice. In an accident bulkheads can easily buckle and cut through the antenna cables making the ELT useless.
