On the landing approach, the airplane encountered turbulence or a downdraft, which resulted in the airplane landing hard on its nose gear. The nose gear separated and the airplane nosed over on its back, which resulted in substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that there was a crosswind which was aggravated by a line of trees along the side of the runway, making the air turbulent.
