I have owned my RV-4 for about 2 years and approx 400 hours now. The airplane now has around 1500 hours TT. The airplane had always flown great, very straight. A couple months ago I developed a heavy right wing. At 150-155kts IAS if I release the stick it will make a sharp departure to the right. At slower speeds, around 100kts IAS it is still noticeable, and at approach speeds it is much less, barely noticeable. My friends who are builders have told me to install an aileron trim tab, but that doesn’t seem right to me as the airplane always flew straight before. I don’t remember any hard or heavy landings that would’ve damaged anything. I’ve looked under the belly and down the wings, I see no buckled panels or indications of damage. The firewall does not appear damaged. Is there something you could recommend for me to check?
I had this issue once before and found that a screw on the top fairing around the stabilizer had come lose allowing the fairing to pull away from the aircraft. I tightened the screw and things went back to normal, nice and straight. I had hoped this was the issue again, but it was not unfortunately.
Thanks in advance for any suggestions.
