I was on Visual Approach backed up with the RNAV Approach. On Visual Approach had a couple big down drafts around 1500 ft. with some precipitation when I went near a big dark cloud. The rest of approach was normal. Fully configured by 1;000 ft and on speed and glide path stable approach. The winds reported were variable at 4 kts. Over the threshold began to flare and pull engine to idle; at about 15-20 ft; at 115 kts; all lift went away; felt bottom drop out of us; and aircraft dropped approximately 15 ft to runway. Control inputs did very little to correct situation to arrest the increased rate of descent. I got a big tail wind gust or got caught in a microburst of some sort. The aircraft slammed onto the runway right main first; breaking and collapsing the right main gear. I slid down runway 2;000 ft. or so before leaving the pavement to the right. No injuries. Pilot and passenger unhurt.
Pilot reported a possible microburst or other weather event resulted in a hard landing that caused a runway excursion and damage to the aircraft.
