Our flying club has had its planes outside for 40 years. For the last
10-15 years or so, it's been all PA28s and PA32s. We've never had a
problem with freezing inside the stabs, but we use stab covers. A bigger
problem in my experience is the stab cover holding the water that melts
off the stab against the bottom of the stab where it refreezes. You've
got to be careful to get that all off.

My stab covers have quite a few gromits in the bottom to let the water
out -- I didn't notice any problems last winter, but I'll keep an eye
on it.


All the best,
