I am not an expert either and don't want to be an alarmist but --- Perhaps you should contact an expert. I would take the problem seriously as you obviously are and be concerned that the aileron vibration might couple with the wing and cause a wing flutter which would be a very serious situation. Flutter is more apt to occur at high speeds, high altitudes and low wing fuel levels. Perhaps Don could assist. Maybe Martin Holmann who monitors this site would give you some free initial guidance via E-mail. Until the problem is resolved, I would either ground the aircraft or fly carefully under the expert's tutelage with full fuel tanks, slow TAS and at low altitudes. Do not accept this situation as normal. How big is the oscilllation at the ailerons trailing edge?
