What happened
While on short final for landing at a one-way-in airstrip, the pilot experienced a slight push from above and behind the aircraft. At the time of the accident, the wind was reported as being from 030 degrees at 12 knots, creating a quartering right tailwind.
In response to the initial disturbance, the pilot applied up-elevator and a small amount of power. Approximately one second later, the aircraft encountered what the pilot described as a powerful, yet smooth downdraft or wind shear, causing the airplane to descend toward the tall grass overrun.
The pilot applied full power and up-elevator in an attempt to recover; however, the aircraft continued its descent. The plane struck the ground at approximately 60 knots, roughly 50 feet short of the airstrip. During the subsequent landing roll, the nose gear collapsed, causing the airplane to nose down. The right wing made contact with the surface, and the aircraft spun approximately 60 degrees to the right. The pilot was not injured.
