Flap Tube ?

[JohnJMoran@aol.com]

The flap tube has a low point at the center which would retain water if it
should enter while the aircraft is on the trailer. While I will coat the
inside of the tube by sloshing thinned par-al-ketone through it, I wonder if a
1/16 drain should be drilled at the low point?  Would this weaken it
significantly or tend to cause cracking?
