Narrative:

As usual I always put the gear down on final approach fix. Verified 3 green lights on approach and over threshold to land. After touchdown heard noise and skidded to complete stop. Damaging propellers, right outboard wingtip and skin on engine nacelle. No injuries, no visible damage to ailerons or structures. Nosewheel and right main gear collapsed causing loss of directional control and damage. In all my experience of accident and incident free flying, I cannot explain the cause of this event at this point.
