A factor was the pilot's lack of qualification and total experience in the accident airplane make and model. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, approach - vfr pattern - final approach - directional control - not maintained, pilot in command (cause) - qualification, pilot in command (contributing factor) - lack of total experience in kind of aircraft, pilot in command (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - water ## Analysis The pilot stated he was conducting a visual approach to a lake for landing. He was about 20 feet above the water when the right wing went up and the left wing went down. The pilot stated he lost directional control of the airplane and the left wing collided with the water separating the outboard leading edge of the left wing. The pilot stated he did not experience any mechanical problems with the experimental amphibian airplane before the accident. The pilot stated he received 22 hours of instruction towards a seaplane rating, however he did not take the FAA check ride and does not hold a seaplane rating. In addition the pilot stated he has 6 total flight hours in the accident airplane. Review of the Saint Petersburg/ Clearwater International Airport, Saint Petersburg, Florida,1553 surface weather observation located 5 miles south of the airport revealed the winds were 330 degrees at 10 knots and no wind gusts were reported. ## Factual narrative The pilot stated he was conducting a visual approach to a lake for landing.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
