O
nly bad things happen if you don’t
cap, bag, or cover lines, tubes and fit-
tings when you pull PM on your aircraft.
❁
Dirt gets into open lines, contami-
nates fluids and grits up connectors so
they won’t seal.
❁
Moisture dilutes lube and keeps it
from doing its job.
❁
Threads get smashed and delicate
connector pins get broken or bent.

All Aircraft…
Make sure you tag all bags so everything
goes back where it’s supposed to go.
If components come with caps and
plugs, use them. Always save caps and
plugs that come with hoses, lines and fit-
tings for re-use. If you have no caps and
plugs, a good PM practice is to bag or
wrap all exposed openings and lines to
prevent fluid spills, moisture and dirt
buildup.
Plastic bags are also great for holding
nuts, bolts, cables and larger compo-
nents that are removed during mainte-
nance and might get dirty or lost. Here
are a few common bag sizes:
