On an RV9 or 9A there's a fairing on the bottom side adjacent to the fuselage that covers up a small cavity at the end of each side flap. This is close proximity to the linkage that operates the flap mechanism. The fairing for this area is a extended piece of fuselage skin which must move with the extension of that Fowler type flap.
After about 750 hours I began to get some vibration noise from that fairing because its only held tight against the fuselage bottom from the spring back in the metal. I suspect the airflow is causing it to vibrate against the fuselage and or flap bracket and causing the noise. Also seeing some cracks and other indications on this moveable piece of fuselage skin was wondering if others have noticed this.
If so, has anyone just completely removed this section and left the hole exposed. Or has anyone come up with a better idea to utilize the fairing or modify the fairing to get a tighter seal . Interested in your comments or ideas for a fix. I'll try to add a link for pic on a later edit.
