While looking over my landing gear, I noticed a crack in the trailing edge of the bottom of the wing fairing. I am not sure how the piece was cracked, but I suspect that I rolled the plane over something and damaged it. The crack goes all the way through the wood.
So it looks like I will have to cut out the damaged material and repair it.
I will follow AC 43.13-1b's directions for repairing wood surfaces, and post the method here.
I wanted to keep the fairing authentic, but looking how easily the wood was cracked, I have changed my mind. I will cover the wood with fabric and then paint it. I believe the fabric will provide additional strength.
