On September 5, 1998, approximately 1320 Pacific daylight time, a Cessna 180J floatplane, N52130, registered to Eugenia Burke, and being operated/flown by a private pilot, incurred substantial damage when the pilot dragged the left wingtip and float while landing on Oysoyoos Lake, Oroville, Washington. The pilot and passenger were uninjured. Visual meteorological conditions existed and no flight plan had been filed. The flight, which was personal, was to have been operated under 14CFR91, and originated from the accident site approximately 10 minutes earlier. The pilot reported to an inspector from the Federal Aviation Administration's Spokane Flight Standards District that "he was landing south on the lake and that the crosswind conditions were not strong. Upon landing the left wing contacted the water and the aircraft spun around and then overturned. Both pilot and passenger exited without injuries." The pilot also confirmed no aircraft component malfunction or failure during the event. The pilot reported on his submitted NTSB form 6120.1/2 that he was: "1. Coming in for landing on glassy, smooth water." "2. Too much nose down." "3. Left float and left wingtip hit water." "4. Plane spun around and flipped over."
