Incident Summary
A pilot reported that while on a short final approach to land on a gravel bar, the aircraft encountered a downdraft. To avoid contacting the water, the pilot corrected with elevator control and power. However, the aircraft gained more altitude than desired.
Landing and Nose-Over
Subsequently, the aircraft touched down on the gravel bar beyond the intended touchdown point. As the pilot was applying heavy braking to stop on the gravel bar, the wheels dug into the sandy terrain and the aircraft nosed over.
Conditions
The incident occurred while landing on a gravel bar. The terrain consisted of sandy material that contributed to the wheels digging in during heavy braking. The downdraft encountered on short final influenced the approach, leading to a higher than desired altitude correction.
