Tanana

A twin-engine airplane on a scheduled passenger/cargo flight, departed a rural airport located along the north shore of the Yukon River with only the pilot aboard. The airplane appeared to depart normally, but remained low, flying over the river, about 200 feet above the ground. About five minutes after departure, the pilot contacted a local weather observation facility on the common traffic advisory frequency (CTAF), and reported he was having a problem with the airplane, stating he may have to ditch. He did not describe the nature of the problem. The pilot then said he was clipping trees, and was attempting to return to the runway. The airplane collided with several trees located on a gravel bar in the Yukon River, separating the outboard end of the left wing. The airplane then collided with the river and sank, about 1.5 miles south of the airport. A fast river current, and silty water conditions hampered recovery efforts, but the left wing, the left engine, and the fuselage were recovered from the river. The left engine propeller appeared to be feathered. The right wing and the right engine were not recovered. Postaccident examination of the left engine disclosed no evidence that it was producing power upon impact, or any evidence of any preimpact mechanical malfunction. Inspection of the airframe disclosed no evidence of any preimpact mechanical malfunction.

The airplane collided with a mountain at the 2,936 foot level. At the time of the accident the weather was 500 obscured, visibility two miles, with fog. The airplane was on a company vfr flight plan. The airplane was substantially damaged. The pilot was seriously injured, and the passenger received minor injuries.

The aircraft departed Kotzebue for McGrath, both in Alaksa, at 1315 A.s.t., with nonrefueling stops at Kiana and Tanana. At Tanana Pilot Chefley W. Priest was briefed on en route weather to McGrath as well as on the route and terminal forecasts. He departed Tanana at 1957LT, about an hour before sunset, on a VFR flight plan. An emergency distress call from the aircraft was first heard at 2126LT. There followed several communications between the Beechcraft and the McGrath ground station which issued navigational advice. At or about 2214LT approximately three-quarters of an hour after dark and during rain showers, the aircraft struck the ground violently in a steep spiral at a point about 26 miles from the McGrath Airport. This accident appears to have been caused by the pilot's loss of control during instrument flight and his failure to recover. All eight occupants were killed.
