Accident: Crescent Lake, AK. 12-Aug-1992. Approximately 5 seconds after levelling the wings on final approach for a glassy water landing on a large lake, the airplane experienced a hard premature landing. The floats were separated, and the airplane sank immediately. The pilot said that because of the flat lighting and glassy water conditions he lost his depth perception and misjudged his altitude. He said when the airplane hit the water he thought he was still 70 to 80 feet above the water. NTSB report ANC92LA128.

Accident: 50 mi. NW Talkeetna, AK, 15-Apr-2005. The airline transport pilot was conducting a federal public use flight for the National Park Service under Title 14, CFR Part 91, when he landed a ski-equipped airplane on a glacier. In a written statement to the NTSB, the pilot reported exiting the landing area in a wide right-hand turn attempting to keep high on the slope, and avoid a depression on the steeply sloping terrain. He wrote that when the tailwheel started to slide downhill, he added power to increase rudder authority, and shallowed the right turn, hoping to avoid a depression. He reported that the airplane crossed over the depression, and upon "touching down on the far side" the right main landing gear collapsed, and the right wing struck the snow. The pilot reported that the right wing and forward fuselage sustained structural damage. According to the pilot, there were no known pre-accident mechanical anomalies with the airplane. Two passengers received minor injuries and pilot none. Aircraft received substantial damage. NTSB report ANC05TA058.
