The accident was caused by the pilot's incorrect response to a low rotor RPM warning, specifically maintaining collective pitch to out-climb obstacles, which resulted in a main rotor stall, loss of lift, and subsequent ground impact. Contributing factors included high density altitude operations, limited escape routes from the takeoff site, and operational procedures requiring review for such terrain.
