Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The private pilot had a hard landing during a personal flight in a float-equipped airplane under Title 14, Code of Federal Regulations Part 91. In a written report to the NTSB, the pilot stated, in part: “With the glassy water and the smoke haze I lost my depth perception and hit the water hard.” A postflight examination revealed that the airplane sustained substantial damage to the fuselage. The pilot wrote in his report that the accident could have been prevented by using the shoreline to determine altitude during landing. He noted that there were no preaccident mechanical problems with the airplane.
