REFLECTOR: Water Condensation in Wing Tanks & Sump

[Dennis Martin]

Water is heavily condensed on the INSIDE surface of both caps. Not just a
little, but big drops of water. I'll do some taxi tests tomorrow and see if
there's enough water to drain down into the sump and let you know what
happens. This is not the first time I've found significant water on the
inside of the cap.

Thanks,

Dennis
