Skyvan N2088Z departed Fairbanks International Airport, AK (FAI) on September 1, 2007 on a cargo flight to a remote lodge airstrip (Mystic Lake Lodge), about 82 miles east-northeast of McGrath, Alaska. The gravel surfaced runway was about 1,000 feet long, and about 40 feet wide. During the landing roll it encountered soft terrain. The nose wheel landing gear strut and tire were folded aft and upward, damaging the fuselage structure at the forward edge of the cockpit floor. Temporary repairs were made to the airframe, and a new nose gear assembly was installed by company maintenance personnel. The pilot was to fly the airplane to the company maintenance facility in Anchorage. The airplane was issued a ferry permit by the Federal Aviation Administration (FAA) Anchorage Flight Standards District Office (FSDO). The ferry flight was planned for September 20, 2007.
The Mystic Lake Lodge owner, who was the only person at the lodge, reported that the pilot started the airplane's turboprop engines and taxied the length of the airstrip, stopping momentarily several times. He indicated that the pilot ran the engines for about 20 minutes, and then began the takeoff run toward the south. The airplane appeared to accelerate and remain on the centerline of the airstrip, but did not lift off until the very end of the airstrip. The owner did not notice any unusual sounds or appearance of the engines. After liftoff, the wheels of the airplane struck and broke off the tops of trees and shrubs, that were about 6 to 7 feet above the ground. The airplane immediately veered to the right and crashed into Amos Lake, coming to rest about 300 feet from shore in about 5 feet of water. The entire cockpit area, forward of the wings, was destroyed.
