The NTSB's narrative final · quoted from the NTSB record

The amphibian airplane sustained substantial damage when it nosed over during the landing roll on a soft, grass runway with the landing gear in the down position. The pilot reported he decided to land on the grass runway instead of the available asphalt runway because of favorable winds. The landing was normal until about 150 feet into the landing roll. The pilot reported that the small castoring wheels on the amphibian floats sank into the soft ground, and "caused our plane to pole-vault onto its tail." Inspection of the runway revealed that there was about 3/4 inch of standing water on the runway. The left and right landing gear drag braces and the left and right nose wheel castor housings were sent to the Materials Laboratory at the National Transportation Safety Board for inspection. The metallurgical inspection revealed that the fracture surfaces of the weld between the forward end of the struts, and the castor bodies exhibited deformation consistent with overstress with the nose wheel moving aft relative to the strut.
