Water inside after monsoon and tiedown

[MyNameIsNobody]

I had my plane tied down through a pretty heavy rain event in Wisconsin this past weekend.  I have a a Bruce's Custom Cover.  When I removed cover and climbed into plane I noticed several drips from ceiling in vicinity of overhead vents/headliner.  Plane is usually hangered except when away from home.  Anybody else ever experience this event?  I was not happy with my decision to wave the overnight hanger charge, but thought tied down with cover it would be fine.  Not so much.  I have SB tube compliance completed and the tubes looked good when I had interior out (removed ALL old insulation), but sheesh.  How do you think the water entered?  Through the closed ram air scoop?  Antenna's have silicone and windshield is solid.  Area by side-Windows is to low for headliner dripping...

Just thought I would pass along my experience.  Those covers are NOT waterproof in a sustained rain/gully washer.

Yikes, that sounds awful.  Did you put a dehumidifier in it for a couple days to dry it all out really well before you put it back together?

Plane did not appear "wet", but there were drips.  I re-did interior/removed old original insulation several years ago, so plastic around tubes not insulation that would retain moisture.  Just a head-scratcher on how it got in with cover in place, vents closed.

Sunbrella fabric loses it's water repellency after a while, go to a camping store and look for a can of spray on water repellent. Or just tape close from the outside the air scoop.

My ceiling would get wet aft of the vents. Turned out the drain tube was disconnected from the vent box.

Verify the drain tube is not kinked or clogged. You can check this by pouring water into the vent and checking for draining out of the drain tube into the floor. Check also for wet carpet on the back seats. Leaks on the windshield front panels are the source.

it was disconnected. I just spliced the two ends.

I bet my drain tube is blocked or disconnected.  I will check that out.  Thanks for the photo.  Is the tube right off the back in center of roof or on the sidewall Co-pilot or pilot?  

[rbridges]

Center of the roof. Close to the rear seats.

Lost my pitot tube cover in the storm...Kind of like losing a friend. (I bought it when I bought the plane)....

Gone with the wind.
