Narrative:

On very short final at approximately 60 KTS, 20 ft AGL, on centerline, a very strong downward/left rolling force was encountered. Aircraft went from 5-10 degrees nose down, wings level to 10-15 degrees nose down, left wing about 10 degrees down and impacted runway slightly left of centerline, bounced once, and came to a halt. Full aft stick and full left stick were applied simultaneously.
