NTSB summary
On September 21, 2005, approximately 1650 Pacific daylight time, a Cessna 170A, N9527A, impacted power lines crossing the Pend Oreille River about one mile north of Box Canyon Dam, near Ione, Washington. The airline transport pilot, who was the sole occupant, received fatal injuries, and the aircraft, which is owned and operated by the pilot, sustained substantial damage. The flight was operating in visual meteorological conditions at the time of the accident. The aircraft was last seen at the Lake Sullivan State Airstrip, and it reportedly departed there about 30 minutes prior to the accident. It is believed that the pilot was on a local pleasure flight, with an intended ultimate return to Lake Sullivan. There was no report of an ELT activation. No flight plan had been filed. According to witnesses, the aircraft was first noticed going to the north, flying low over the trees along the side of the Pend Oreille River. It then reversed course and headed to the south at 100 feet or less above the river. The aircraft was then seen to impact a pair of unmarked power transmission wires that run across the river about one mile north of the Box Canyon Dam. Immediately upon contacting the power lines, the aircraft's pitch attitude rotated to a near vertical position, and it descended nearly straight down into the river. In less than two minutes after hitting the surface of the river, the aircraft sank in about 10 feet of water. It was later determined that the power lines were between 80 and 90 feet above the surface of the river. An inspection of the aircraft after it was recovered
Probable cause
The pilot's failure during low-level maneuvering flight, to maintain clearance from a pair of unmarked power lines. Factors include the pilot's intentional low altitude flight/maneuver and wires.
