NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On September 4, 2017 about 1430 Alaska daylight time, an amphibious float-equipped Cessna U206 airplane, N16GP, sustained substantial damage while attempting to depart the water at Trident Basin Seaplane Base, Kodiak, Alaska. The airplane was registered to and being operated by the pilot as a 14 Code of Federal Regulations Part 91 visual flight rules flight. The certificated airline transport pilot and three passengers were not injured. Marginal visual meteorological conditions existed and no flight plan had been filed. 

In a written statement to the National Transportation Safety Board (NTSB), the pilot stated that during the takeoff run the airplane encountered small swells, and began to lose speed while simultaneously pitching forward. In an effort to correct for the forward pitching moment, the pilot applied full aft elevator. Shortly thereafter, he aborted the takeoff, but the airplane continued to pitch forward when it was struck by a larger swell. The right forward float strut fractured and the airplane rolled to the right, which resulted in substantial damage to the right wing's lift strut. An initial examination of the airplane by the pilot revealed that the left nose wheel was partially deployed with the landing gear handle in the up position. 

The airplane was equipped with EDO 3500 amphibious floats. 

A detailed wreckage examination is pending.
