I have a wrinkle in the lower trailing edge skin of my rudder. It has never been hit, or hit anything. The first time I saw it on the right side I thought the rudder had swung in the wind and hit the stop maybe causing the TE to travel further. I pulled the last 3 rivets and got behind the skin and straighten it out. Since then I have always used a gust lock. At that time the left side was not affected. It is now several hundred hours later and both sides are wrinkled. The rudder is stiff, I can't flex it to move the wrinkle. I can’t figure out what could be causing this.
Has anyone else seen this?
