Rain

[Big Ed]

I've always been told that T&F aircraft need to stay hangared for longevity, to reduce UV exposure on the fabric and dope. I've also been told to avoid rain, which might accelerate the corrosion of steel tubes in the fuselage and tail feathers.

When I planned my first multi day XC trip, I selected destinations with transient hangars. Last night I get to my final stop and the hangar is full, so I can only get a night time tiedown. Of course it rains buckets all night long.

Should I stress about this?

No. Parked in the rain for an overnight shouldn't be a problem. It's the long term exposure (tied down outside for years) that will take its toll.

I'm way less concerned about properly painted polyester fabric planes being damaged by sun than I am about water ingress through the many surface penetrations. The wing root covers, fuel filler necks, control surface hinges, antennas, etc.

Just like anything dropped in the cabin, it goes straight to the back of the plane. Those lower longerons in the tail would be the main victim.

If you have to park outside for weeks or months, like waiting for a hangar to open up, then investing in a good cabin cover that extends out over the fuel fillers, at least part way forward over the boot cowl and aft of the plate behind the cockpit (some people have beacons there, I only have an ELT antenna) would be a minimum.

Some people get the full covers which is fine, but there's a Bonanaza at my field with the full kit and it sure beats the crap out of the paint in a wind storm.

My Cub spent 15 years outside in coastal SoCal. So far so good - can still see reflections in my 40 year old acrylic enamel finish. In a beautiful hangar now.

The secret is to fly it after each rain event. It needs to dry out completely. Let it sit for an entire reainy season and expect major corrosion damage.
