HEMMER MINI-MAX 1600R near Davis, CA — 2010-08-08

Probable cause

The airplane’s encounter with the wake turbulence of another aircraft.

NTSB narrative

The pilot reported that while flying on the downwind leg of the traffic pattern in a single seat, tailwheel-equipped ultralight type airplane, he observed a Cessna airplane take off from the runway. When the Cessna was clear of the runway, the pilot conducted an uneventful wheel landing. During the landing roll, as the airplane approached the area where the Cessna lifted off, the airplane lifted off of the runway surface. The pilot applied full power but the airplane touched down hard, substantially damaging the wings and fuselage. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine.
