On October 4, 2000, about 1810 Alaska daylight time, a wheel equipped Curtis Wright C-46F airplane, N1822M, sustained substantial damage after landing at the Port Alsworth Airport, Port Alsworth, Alaska. The airplane was being operated as a visual flight rules (VFR) cargo flight under Title 14, CFR Part 125, when the accident occurred. The airplane was registered to, and operated by, Everts Air Fuel, Inc., Fairbanks, Alaska. The first pilot, a certificated airline transport pilot, and the second pilot, a certificated commercial pilot, were not injured. Visual meteorological conditions prevailed, and a company flight plan was in effect. The flight originated at the Fairbanks International Airport, Fairbanks, about 1600. During a telephone conversation with the National Transportation Safety Board investigator-in-charge on October 5, the captain indicated that he had landed and was taxiing to the parking area. He related that as he turned the airplane to the right to enter a taxiway, the left wingtip struck a tree. The airplane sustained substantial damage to the outboard portion of the left wingtip and left aileron.
