NTSB summary
HISTORY OF FLIGHT On September 7, 1993, at approximately 1600 Alaska daylight time, a tundra tire-equipped Interstate S-1B2 Arctic Tern airplane, N64AT, crashed on takeoff from a gravel bar strip on the Talkeetna River, approximately 40 miles northeast of Talkeetna, Alaska, seriously injuring the private pilot and his passenger. The two were reported overdue that day by the next of kin and the crash site was located at approximately 2000 on September 8, 1993. No flight plan was filed by the pilot who had told relatives that they planned to return to Anchorage on September 7, following two days of hunting. The flight was conducted under 14 CFR Part 91 for personal reasons. The pilot was interviewed by investigators on November 19, 1993. He recalled that he had departed Anchorage at approximately 0900 on September 5, 1993, flying one hour to Talkeetna where he picked his passenger, Mr. Scott Weber of Anchorage. The two then flew to the Talkeetna River bar strip, landing at approximately 1030. He said that he had used approximately 1.5 hours (he estimated 15 gallons were used) from his fully fueled wing and belly tanks. He said that his aircraft held 40 gallons in the wings and 32 gallons in the belly tank. Asked about weight and balance information, he recalled that the airplane had a 900 pound useful load, that information being provided by the manufacturer at the time of a complete rebuild by the Alaska company, two years prior to the accident.
