Water in the rudder is a fairly common occurrence. Usually it comes in where
the post enters the rudder body unless there is some impact damage somewhere
else. One way to fix it is: 1, sand/grind it down to bare glass and inspect
for cracks/damage. 2. Drill a few holes, ½ “ should do, at the top and
bottom. You will probably have water coming out of the bottom. 3. Let it
drain. This may take a while (days maybe longer). If you can, hang it in a
somewhat “climate controlled” environment. I did one in the laundry room in
my house once. Once it’s dry or you run out of time/patience, fix the holes
and repaint.

If you really want to get carried away, vacuum bag it

Not to sound like a doom sayer but if left to run it’s eventual course, the
water will cause the rudder to delaminate and fail but that could take years
if not decades. It’s more of a problem if you’re in a place with a
freeze/thaw cycle.

Good luck and happy grinding

Subject: [IC27A] Rudder leakage

 

  

Folks:

Noticed an issue when I put "Liebchen" on her jack stands last fall. I have
water weeping out of some tiny cracks in the rudder. I'm not sure where the
water is coming from, but it could be either a crack around the rudder post
at the top of the rudder, or those small cracks I mentioned.

Any ideas as to finding the culprit, and/or eliminating the water leak(s)
without replacing the rudder? 

Thanks!!
