Probable cause

The pilot’s failure to maintain pitch control during takeoff after encountering a boat wake, which resulted in the airplane bouncing, impacting the water’s surface, and subsequently becoming submerged.

What happened

According to witnesses, the private pilot of the experimental, amateur-built, high-wing, amphibious airplane was attempting to take off from the lake, which was choppy due to numerous boat wakes. Witnesses reported that the airplane started a high-speed run but that the engine then throttled back, and the airplane turned toward the beach. The airplane then abruptly turned 180 degrees and started another high-speed run. While on the step for the final takeoff attempt, the airplane encountered a boat wake, bounced 4 to 5 ft, and then abruptly nosed down into the lake. The airplane came to an abrupt stop with a 20- to 30-ft-high splash. When witnesses arrived in their boats, the airplane's high wings were level with the water's surface, and the aft-facing, pylon-mounted engine was still running. Swimmers entered the water and recovered the pilot from the submerged cabin. Shortly thereafter, the airplane sank. The submerged airplane could not be located during a subsequent search by local law enforcement, and the wreckage was not recovered.
