Times, headings, measurements and altitudes are approximate. On July 2, 2016, N42469, a Cessna C-182L, the private pilot; took off from the great falls airport (kgtf), Montana, and flew to choteau (cii), Montana, to pick up three passengers to go to Schafer Meadows Usfs (8U2), Montana, for a backpacking trip. Upon arrival in cii, two of the three passengers and one backpack were loaded in the aircraft for the flight to 8U2. Visual meteorological conditions existed at the time. No flight plan was filed.

The pilot set 20 degrees of flaps for landing. On his first attempt to land, he realized he was going too fast, and did a go-around. On his second attempt at 0800 MDT, he touched down after flying over the the first 300 feet to avoid that rough part of the runway. He applied brakes but the aircraft did not slow down, and slid down the runway. When he got to the end of the runway over run, there is an earthen berm that made a ramp at the end of the over run. The aircraft came off the berm at a climb angle of attack. Because of this, the aircraft went over the rail fence, and then initially hit the trees about 12 feet off the ground, with first impact on the bottom of the aircraft wings and fuselage.

The aircraft was severely damaged, with the upper fuselage skin seam separating at the rear spar from the crown all the way down the sides to the floor; left lift strut fitting and structure torn out of the aircraft; left door came off, both interior and exterior cabin floor area buckled; all four front seat rails were bent; all four copilot seat feet tangs bent and disengaged from seat rails; and both pilot seat inbd seat feet tangs bent and disengaged from the seat rails. The seat foot wear was not beyond the limits given in AD2001-10-09. The windshield was broken and both rear windows were broken from the flaps hitting them. The right side fuselage from the windows back was torn open by the roots of an uprooted tree. The empennage skin has a series of buckles and bends. The aircraft center console and elevator trim wheel were bent and distorted from the floor buckling. Both wings have severe impact damage, bending damage on the lower and leading edges, with more damage on the top of the wings, with sheet metal torn and rivets pulled out from the force of the impact. The right aileron outboard foot was torn off. Fuel was leaking inside the aircraft. The prop has one bent blade, the other blade did not appear to sustain any damage. All flight controls and engine controls operated. The mixture and prop were still pushed in, and the fuel selector was on both. The landing gear was intact and the tires and brakes were in serviceable condition.

The ELT did not go off.

The pilot had minor injuries, a cut on his chin, (he suspected from the boom on his headset); bruises on his left arm; and he then experienced minor back pain the next day. Both passengers were uninjured. Seat belts were installed and used. No shoulder harnesses were installed in this airplane.
