Upon touching down; the aircraft immediately made an uncommanded right turn. I immediately applied left rudder and brake. This halted the rotation; but my plane was headed for a parked jet on the ramp. I made the decision to apply hard right brake to keep from hitting the parked jet; knowing that it would most likely result in a ground loop. The left landing gear was sheared off; the prop hit with engine running; and the left wing hit the ground.I believe that I probably had some right brake applied when the wheels touched down; which initiated the initial right turn. Upon reflection; I feel that when the foot is on the rudder pedal; maintaining clearance between the toe brakes and rudder is a difficult position for the foot. I plan to mention this to the kit manufacturer. A little more angle would provide a safety factor. Secondly; the long landing gear strut has a weak point at the threads of the long shock; which makes a strong side loads problematic. A reinforcement collar at that location would help in this area. I plan to also mention this to the kit manufacturer. In any case; since this is an experimental classed aircraft; I will make these modifications to my aircraft.
JA30 experimental aircraft pilot reported an immediate uncommanded right turn on touchdown. Left rudder and brake were applied to stop the rotation; but the aircraft was headed for a parked aircraft; so right rudder and brake were applied to avoid them. The left gear was sheared off and the wing hits the ground.
