NTSB Factual Report

The airplane was substantially damaged on impact with a lake during a glassy water landing. The pilot was performing a second flight test of the airplane when, upon landing touchdown, the airplane nosed over. The airplane damage included delamination of hull. The pilot sustained serious injuries, which included a broken right ankle and facial fractures. The airplane was not equipped with an optional shoulder harness restraint system. The pilot did not hold an AP4 logbook endorsement allowing him to pilot float equipped aircraft.

NTSB Probable Cause

The inadequate flare by the pilot during landing. Contributing factors were the lack of an endorsement by the pilot, the lack of total experience in the type of aircraft by the pilot, and the glassy water.
