N824CVans Aircraft RV-6A · 2016

The airplane impacted the runway surface during takeoff after it prematurely lifted off and cartwheeled to a stop facing in the opposite direction. The pilot stated that he knew the airplane was not at flying speed when it lifted off, so he moved the control stick forward to return the airplane to the runway surface, but the airplane bounced and veered left. He added additional engine power in attempt to keep the airplane flying. The left wing then dropped and contacted the runway, cartwheeling the airplane. The pilot reported that there was no mechanical malfunction/failure of the airplane at the time of the accident.

The pilot reported that prior to departure he checked the weather and performed a preflight inspection. He observed the direction of the windsock, and stated that it favored a takeoff from runway 23. He completed an uneventful run-up, and began the takeoff roll. Halfway down the turf runway he observed the airplane's airspeed to be indicating 60 knots. He stated that at this point on the takeoff roll he expected the airspeed to have reached 70 knots. The airplane continued to accelerate to 65 knots, and with the end of the runway approaching, the pilot 'forced' the airplane airborne and retracted the landing gear. The airplane settled to the ground and then collided with trees at the end of the runway. The pilot observed the wind direction after the accident, and noted that it was out of the northeast. He opined that the airplane had encountered a sudden wind shift or downdraft during the takeoff roll.
