Excessive condensation in hangar

[hais]

Should I be concerned about corrosion? Airplane is in a T hanger. The airplane was dry when I pushed in, a week later, looks like this.

I see this is an Ovation. I would advise you to winter this Mooney in Florida, at least until the last snow has melted. I have a warm, dry hangar for you. Of course it should be flown at last once a week. I might be persuaded to keep that engine active, just looking to help out a fellow Mooniac.

I thought the whole point of winter flying was to see something like this, now you can't get this in Florida, can you?

Not quite the same but pretty much anywhere in the state….

Mine lives in a hangar and I ave never seen anything like that and yes I would be concerned. 
 

I think 88V jus dropped the mic and walked away…

Vancouver is pretty nice!

Notes on contact with water…

Water has a tendency to attract a lot of unwanted stuff…

So try to avoid it, unless you can’t….

At the point water is condensing on the plane… the air is at 100% relative humidity….

If that is occurring inside a closed hangar… people use dehumidifiers to keep this from occurring….

If there is a combustion heater warming things in the hangar… this might be a dangerous sign… exhaust products of combustion heaters include a lot of water, and some CO…. Find a better heater… or fix the exhaust on the one that is there….

 

Why you really want to avoid this much water….

Water is an enabler of oxidation…. Any un coated metal in the hangar, with that much moisture, is going to show signs of oxidation…. Especially if it is warm….

 

Pp thoughts only, not a metallurgist…

Try venting the hanger, to maintain a similar temp to the exterior.

Damn…..my roof leaked and the plane was never was that wet…..pop an inspection panel off the wing and see what it looks like inside there…..

Sure you can. Just fly over Miami and look out at the mounds of cocaine piles below.

When this happened to me, it is usually because of rapid weather changes. I found that it only happened a few times a year in my old hangar. A lot of the moisture is condensation that came up through the cracked asphalt floor.

My current hangar is new and has sealed concrete floors. No moisture issues. You might want to try a fan to move air. The aluminum is just a magnet for condensation.

Push airplane in hangar on a day when the dew point is in the 60's (or 70's) and close the door.   Then a cold front goes through.   Radiative cooling of the hangar and its contents cools the airplane below the dew point.   Water in the air condenses on the airplane.

If your aircraft doors are closed and your paint is in good shape you have nothing to worry about.  This happens from time to time to all of us living in non-arid climates.  Those beads of water will evaporate away over time.  You can towel them off if you want.

No one on the course playing.  In the hospital with Covid I guess.

I’d open the battery panel and check if you have moisture on the inside as well. If yes, I would invest in a dehumidifier.

I see this at my hangar when the warm front comes up form the gulf of Mexico after a nice cold front.

During Winter I run a de-humidifier, last summer I Installed a mini-split and use a humidistat for Summer

They don’t pull as much power as you think and the dehumidifier pulls about 5 gl of water s day from the air.

I did some looking on the internet and both 6061 and 2024 aluminum’s rates of corrosion graph gets steep at 65% RH, so I keep the hanger at 60 or below.

Your tools etc will last much longer too.

Oh and I’m in Fl, Fl is humid just like the rest of the world, actually I think much more humid in Winter then the Great White North.

This happens with quick temp changes to me at KSBY in Maryland. I posed on Mooney FB group about it. There is not much we can do. Just pray you have an engine heater at least to keep this mositrue out of that compartment. I heat 24/7 and this keeps this from happening under my cowling.

Yes, we're dropping like flies here in Florida. Hospitals are overflowing and the morgues are taking reservations. I would advise you to stay far away from Florida. Tell your friends too.

I have had condensation on the hangar ceiling rain down on the plane. I mounted a fan up high and run it in the winter to keep the air circulating. It seems to help. I have had only minor moisture since installing the fan.

Dude sounds like it was a hit. Glad you made it and safely. Landing up in springfield hartness VT I got to experience my first icy landing. I just kept off the brakes and used the rudder like a tail dragger to keep things stright. Now... Here comes the funny part. I park about 150 FT from the power source... its -18. In my brain the engine is rapidly cooling and im losing prechious time... I grab the tow bar and start pulling her towards the power...BOOOM I slip and fall on ice while I am towing the airplane and SMACK my back into the -18F degree ground. Luckily with all of the jackets on it only gave me a good scare & a nice bruise but I laid on the ground thinking "Something is boken, what Will happen to the airplane"... HA
