HENRIE RAYMOND ZENITH CH 701 STOL

Full Narrative

The pilot was attempting to depart the airport to return home in the experimental light sport aircraft. According to the pilot’s statement, just before takeoff, he noted that the windsock was “still” and initiated his takeoff roll. About 20 feet above ground level (agl), the flight encountered a left crosswind causing the airplane to go to the right. He corrected by immediately applying left aileron and left rudder control inputs, then removed the aileron and rudder control inputs. The flight continued and about 30 feet agl, the flight encountered another wind gust that pushed the airplane to the right “faster” than he could apply corrections. The right wingtip impacted a treetop causing the airplane to reverse its direction, descend rapidly, and impact the ground causing structural damage to the wings and fuselage. The pilot reported no preimpact mechanical failures or malfunctions. A representative of the airplane designer reported to NTSB that a 10 knot crosswind is well within the airplane’s maximum demonstrated crosswind limitation.
