Narrative:
Wind was quartering from the left at 15 gusting to 25. This aircraft is capable of flight at speeds in the low 20's. During the flare to land; the wind gusted and there was insufficient control authority to maintain control of the roll rate of the aircraft. Some scraping of the outboard edge of the right aileron was the result.I discovered that this type of incident is a common occurrence with this aircraft make and model. There is a spoiler kit available that is designed to improve roll authority at slow speed; which I have purchased.during my discussion of this matter with an instructor familiar with this airplane I learned that roll at very low speed should be mostly controlled with the rudder. I will incorporate this instruction into my future training and procedures.
