A pilot on her first solo flight in a seaplane reported a landing accident after misjudging water conditions, with the aircraft careening and cartwheeling before coming to rest upright.

Accident Details

According to the pilot's report, while preparing to land, she observed mild ripples on the water surface and concluded the conditions were not glassy. She opted for a flatter approach than normal. As the airplane descended toward the water, the haze became thicker. The pilot recalled questioning whether she should have set up for a glassy water landing, at which point the aircraft struck the water.

Sequence of Events

Upon contacting the water, the airplane veered to the right, then performed a cartwheel motion to the left. The left wing subsequently struck the water, and the aircraft finally came to rest in an upright position.

Pilot Background

The pilot had recently completed her single-engine sea checkride approximately two weeks prior to the accident. This flight was her first solo flight since earning the rating.

Investigation Findings

No further details regarding injuries, aircraft damage, or weather conditions were provided in the report. The investigation did not specify a probable cause.
