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. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, landing - flare/touchdown - lack of total experience in type of aircraft, pilot in command (contributing factor) - misc eqpt/furnishings,shoulder harness - not installed - flare - inadequate, pilot in command (cause) - lack of certification, pilot in command (contributing factor) - Nose over, landing - flare/touchdown - terrain condition - water,glassy (contributing factor) ## Analysis 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. ## Factual narrative The airplane was substantially damaged on impact with a lake during a glassy water landing.
