Aircraft Aircraft Damaged
During visual approach to landing at ZZZ Runway XXL; on short final; the aircraft began to yaw significantly to the right. The pilot corrected with rudder just prior to flare. The pilot noted that the amount of rudder needed was excessive to what is normally required considering current conditions. The aircraft banked uncontrollably to the right just prior to touchdown and the right wing tip and made contact with the ground. The aircraft pulled hard to the right and came down on all three wheels. As the aircraft departed the runway; the nose gear collapsed upon contact with the dirt. The aircraft came to a stop. The pilot alerted ATC that he was ok; shut off the batteries and egressed from the aircraft through the forward cabin door. The pilot awaited Airport Ops and rescue personnel next to the aircraft and provided all requested information. No physical injuries were noted on the pilot. Unverified cause of uncommanded yaw and bank prior to touchdown. Suspected Right Engine thrust deficiency and possible excessive drag prior to touchdown. Pilot egressed aircraft after coming to a stop. Assisted with local authorities in assessment post incident.
