aviation accident: PIPER PA-28 near Cottonwood (2013-05-07)
Probable cause: The student pilot's decision to attempt a night landing on an unlit runway, which resulted in a misaligned approach and subsequent collision with a fence. Contributing to the accident was the student pilot's improper set-up of the airplane radios, which resulted in his inability to activate the airport runway lights, and his mistaken identification of building lights for runway lights.
