He thought it might have been due to slightly hard braking, so he released the brakes, and the airplane nosed over. The airplane sustained substantial damage to the left wing. About 2 years before the accident, the Arizona Pilot's Association and The Recreational Aviation Foundation issued a pamphlet about the accident airport. It stated that the airport had multiple hazards, including varying surface conditions and hard and soft areas. It also stated to use "at your own risk" and "injury and loss of aircraft are possible." ## Factual narrative The pilot of the tailwheel-equipped airplane reported that, during landing on a backcountry dirt airstrip in calm wind, the airplane decelerated, but the tail would not come down.
