On October 13, 2017 at about 10:34 pm local time, a 1975 Cessna 172M, registered N7CF, was destroyed in an accident during maneuvering (low-alt flying) near Ramsey, Minnesota. It was a personal flight under general aviation rules (Part 91). 2 people were killed. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The pilot's decision to fly along the river at a low altitude contrary to applicable regulations and safety of flight considerations which resulted in the impact with the power lines. Contributing to the accident was the pilot's inability to see the and avoid the power lines due to their proximity to a bend in the river and the position of the sun at the time of the accident.

The NTSB's narrative final · quoted from the NTSB record

After takeoff, the pilot proceeded south until reaching the Mississippi River when he proceeded to fly along the river at a low altitude. As the airplane approached a bend in the river, the pilot entered a shallow left turn to follow the river. The airplane subsequently struck power lines spanning the river that were located about 200 yards beyond the bend. Ground-based video footage and witness statements indicated that the airplane was at or below the height of the trees lining both sides of the river shortly before encountering the power lines. One witness initially thought that the pilot intended to fly under the power lines due to the low altitude of the airplane. Several witnesses also noted that the sound of the engine seemed normal and steady before the accident. A post-recovery examination of the airplane did not reveal any anomalies consistent with a preimpact failure or malfunction. The power lines were below the level the trees on either side of the river. Red aerial marker balls were installed on the power lines at the time of the accident. Weather conditions were good at the time of the accident; however, the sun was about 9° above the horizon and aligned with the river. It is likely that the position of the sun in relation to the power lines hindered the pilot's ability to identify the hazard as he navigated the bend in the river at low altitude. In addition, the location of the power lines relative to the river bend minimized the reaction time to avoid the lines. FAA regulations prohibit operation of an aircraft less than 500 feet above the surface in uncongested areas unless approaching to land or taking off, and at least 1,000 feet from obstacles in congested areas. They also prohibit operations in a reckless manner that endanger the life or property of another. Based on the available information, the airplane was less than 100 feet above the river and within 400 feet of the residences located along the river during the final portion of the flight. The pilot's flight instructor described the pilot as "reckless" because of his habit of low-level flying. While the location of the bend in the river and the position of the sun relative to the power lines may have hindered the pilot's ability to see and avoid the lines, it was the pilot's decision to operate the airplane along the river at a low altitude contrary to applicable regulations and safety of flight considerations that caused the accident.
