Catheter question

One thing to watch out for is where the urine goes once it is outside
the aircraft as it is very corrosive to metal parts. During my annual
yesterday we found some unusual corrosion on the aileron bellcrank
mount. All other controls are in great shape. There is a drain hole in
the fusilage just aft of the gear doors and the drain tube termination.
I am speculating that some of the urine 'mist' may be getting inside
the fusilage and causing the corrosion. The mount is directly aft of
this drain hole and of course inside the fusilage.

I have also heard from other pilots of corrosion in the wheel and brake
areas due to this problem.

Of course you can prevent or remedy this problem. I am going to plug
the drain hole and the wheel problem could be remedied with regular
cleaning. The point is that you need to beware of where on your
aircraft the urinne may be depositied and take care of it.

I really think a catheter is the way to go because you need to nothing
else but think about it and it is done! But I am now thinking I may
have the tube go into a baggie filled with an absorbant material
instead of releasing the urine under the glider.
