Monponsett Pond Airport
Aircraft Accident/Incident Report

Halifax, Massachusetts 02338
Wednesday, May 12, 2004 10:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was practicing takeoffs and landings on a pond. During an approach to the pond, the pilot noted that the winds were light and variable, which caused glassy water conditions. Prior to the landing flare, the pilot was having difficulty referencing his height above the water. Subsequently, the airplane impacted the water nose-low. The float tips submerged, and the airplane came to rest inverted.

NTSB Probable Cause Narrative

The pilot's inadequate flare during landing, which resulted in an in-flight collision with water. A factor was the glassy water conditions.
