On August 24, 2003, about 1500 AK daylight time, the aircraft sustained substantial damage following a loss of control while landing at a private airstrip, located approximately 25 miles northwest of Kenai, AK. The solo commercial pilot/airplane owner was not injured. The Title 14, CFR Part 91 personal flight operated in visual meteorological conditions without a flight plan. The flight departed the Lake Hood Strip, Anchorage, AK, about 1330, and the destination was the private airstrip. During a telephone conversation with the National Transportation Safety Board investigator-in-charge (IIC) on August 25, at 1415, the pilot related he was landing to the south on the gravel-surfaced airstrip. He said there was a direct crosswind from the east at 5 to 10 knots, and shortly after he lowered the tailwheel during the landing roll, he lost control of the airplane and it ground-looped to the left. He reported that the right landing gear leg was bent, and the right wing was snapped-off about 4 feet inboard from the wingtip. He said there were no preaccident mechanical problems with the airplane. NTSB report ANC03LA102.

Accident: King Salmon, AK. 05-Oct-2009. The pilot reported he was departing to the east with a 5-knot tailwind, in a float-equipped aircraft. He said that the purpose of the flight was to demobilise a remote fishing lodge at the end of the season. The pilot reported that during the takeoff run he realised that the aircraft would not become airborne before reaching the departure end of the lake, and he closed the engine throttle in an attempt to abort the takeoff. The floats struck the shoreline, and the aircraft came to rest on the shore, about 75 yds from the lake, sustaining substantial damage to the right wing. The pilot indicated that there were no pre-accident mechanical problems with the aircraft and in his written report to the NTSB he attributed the accident to “pilot error.” ANC10CA001.
