During A Low Pass Over A Gravel Bar, The Airplane’S Tailwheel Impacted An Area Of Rough, Uneven Terrain Analysis: The pilot reported that he was flying low-level over various remote gravel bars looking for a suitable one to land on. During a low pass over a gravel bar, the airplane’s tailwheel impacted an area of rough, uneven terrain, which pivoted the nose of the airplane down, resulting in a hard, inadvertent landing. The main landing gear wheels subsequently impacted a 3 ft high gravel berm, and the main landing gear collapsed resulting in substantial damage to the fuselage and left wing lift struts.
