On the H3s, they have encapsulated toilets. The 1C-130A-23CL-1 step 9 reads:
9. Remove right and left ramp hinge panels and belly band panel. (Required for aircraft with encapsulated toilet, only on wash prior to ISO.)
Wasn\'t the purpose of this actually for planes with the Urinal Drain Tubes? I was thinking it should read \'Not required for...\'. I know it used to get nasty and corroded with the drain tubes in these areas. The way the book reads now, it would never get accomplished on aircraft with drain tubes.
