Helio H-391B
The pilot said there was "a slight crosswind from the left at 10 knots" as he rolled out onto the right side of runway 26 (9,200 feet x 150 feet, concrete, grooved). As the tail wheel lifted off and the front gear started getting "light," a gust of wind started turning the airplane into the wind. Just prior to liftoff, the right gear collapsed and the airplane veered off the runway, buckling the right forward fuselage and firewall. Wind at the time of the accident was from 190 degrees at 13 knots.
