Question Strange leak what is it?

It is not fuel. I opened the covers and checked with mirror. It's not oil too far from the engine. It's not brake fluid all connections checked. Tubes inspected inside, penetrating AN fitting clean fluid level normal.

The spot looks sticky and greasy. Doesn't smell. I didn't taste it


This is how it looks. What is it?

Maybe the grease or lubricant you used to persuade your wing spar bolts into place?

Maybe fiberglass/aluminum chafe residue mixed with water?
I see it all the time.

Unlikely. Why it showed up in the middle of brutal winter and not in July heat of Phase One?

Interesting. A flight was performed not so long ago in pouring rain. Maybe water got inside and washed that chafe

Looks like tire dust mixed with something. Maybe rain? Does it rub off readily?

Default Me too!!!!

...Tire and brake dust that travels up the fairing. I filled them up with expanding foam, stopped this from forming and also stopped most of the 9-A whistle people talk about. Regards, Allan

Or could it be brake fluid leaking and collecting dust/dirt?

I like the brake dust theory. I flew my -6A without wheel pants and leg fairings for a while, then bowed to peer pressure and installed them over Christmas. Every landing is accompanied by a short burst of tire smoke smell from the landing. It took me a little while to figure out that the smoke was traveling up the fairing and into the cockpit. I just plan to use some aluminum tape to close up the gap around the main gear legs and see if that works. I don't know if I want to foam inside the leg fairings...I might need to take them off someday.
