When I went to A&P school (oh so many years ago) they told us that
aircraft cables should NOT be lubercated.

What did they say about lubricating sheathed/enclosed cables such as
throttle, carb heat, and mixture? My experience is that, unless they
have an integral nylon sheath, they do need to be lubricated but LPS-2
in not a good choice.

BTW a review of AC 43.13-1b found this:


7-150. CORROSION AND RUST PREVENTION.
To ensure a satisfactory service life
for aircraft control cables, use a cable lubricant to
reduce internal friction and prevent corrosion.

My poor experience with LPS-2 on aircraft control cables was with the
enclosed throttle cable of my PA28-180.

I have never lubricated open control cables that run over pulleys
although AC43.13-1b does seem to say that is appropriate in some
circumstances.
