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

According to the pilot, he overflew the area of intended landing to check for water depth, wind direction, and verify that it was a suitable landing area. While on final approach to the water, a boat crossed underneath the airplane. As the airplane landed on the water, it struck the boat wake, which resulted in the airplane "skip[ping]" over the water. When the airplane impacted the water again, the front float struts collapsed resulting in substantial damage to the fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation prior to the accident.
