Analysis

Plt was executing low level photographic survey of valleys in mountainous terrain. Acft entered a narrow valley with steeply rising terrain ahead. When plt realized excessive rate of climb would be required to clear obstacles, he attempted a steep turn-around while acft was climbing sharply. Rotor RPM decayed and the acft settled into trees and brush.
