On May 17, 1998, about 1315 Alaska daylight time, a wheel equipped Cessna U206G, N756HG, sustained substantial damage after landing at Iliamna Airport, Iliamna, Alaska. The airplane was being operated as a visual flight rules (VFR) repositioning flight under Title 14 CFR Part 91 when the accident occurred. The airplane is registered to, and operated by, Iliamna Air Taxi, Inc., Iliamna, Alaska. The airline transport certificated pilot, the sole occupant, was not injured. A VFR flight plan was filed. The flight last departed Nondalton, Alaska, at 1245, and the destination was Iliamna. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on May 18, the pilot related that he was returning from Nondalton. A successful landing was made on runway 07 at Iliamna. After landing roll out, the pilot made a left turn onto intersecting runway 35 to taxi to the company parking area. The pilot stated that after he made the turn, it was difficult to maintain directional control due to high winds and a quartering tailwind condition. After taxing about 75 feet, the right wing and tail lifted. The airplane then nosed over, causing substantial damage to the wings, fuselage, doors, and rudder assembly. The pilot stated that the wind conditions at the time of the accident were 080 degrees at 25 knots, with peak gusts to 35 knots.
