Frozen airbrakes are one of these. If you intend to fly at altitude,
or anytime the temperature is below freezing, a layer of vaseline
between the mating surfaces will tyically prevent them freezing
together.

The only time I had the spoilers freeze shut was when a light shower
came through just as I was preparing to tow. We waited until it passed,
then towed off. It turned into a wave flight, freezing the brakes shut,
which I discovered during the descent. They released in the warmer air
at about 4000' agl, so no problem.

Has anyone had the spoilers freeze shut without having rain first, and
without flying in cloud?
