Bolts, nuts and screws: check that they are not loose, missing, bent, or broken. You can't try
them all with a tool, of course, but look for chipped paint, bare metal or rust around bolt heads. Tighten
any bolt, nut, or screw that you find loose.

a bad weld, report it to intermediate direct support.

broken connectors. Tighten loose connections and make sure the wires are in good condition.

from a loose fitting or connector, tighten the fitting or connector. If something is broken or worn out,
either correct it or report it to intermediate direct support (refer to the Maintenance Allocation Chart).
