Aircraft Accident/Incident Report

Chippewa Lake, Ohio 44215
Monday, September 14, 1998 18:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane landed on a smooth lake, and encountered a wake from the only boat that was operating at the time. The pilot increased power to get up 'on step,' and when the airplane hit the wake, it bounced up into the air about 3 feet. It came down into a second wake, the nose dug into the water and broke off, and the airplane flipped over. The pilot's seaplane transition training consisted of a checkout from his partner, and 8 to 10 water landings. He had 34 water landings at the time of the accident. Neither he nor his partner had a 'single-engine sea' airplane class rating. However, 14 CFR Part 61.31(k)(2) stated that rating limitations did not apply, even when carrying passengers, to '(iii) The holder of a pilot certificate when operating an aircraft under the authority of an experimental or provisional aircraft type certificate.' The pilot and his partner had planned on attending formal training during the upcoming winter.

NTSB Probable Cause Narrative

Encounter with swells from a boat wake. A factor in the accident was the pilot's inadequate initial training.
