Analysis

While on a local flt, the acft collided with trees in a canyon. The plt reported the acft's alt was lower than anticipated & the terrain in the canyon rose rapidly. Full eng power was not sufficient to negotiate the rising terrain. The plt reported the acft's airspeed & alt were insufficient to execute a 180 deg turn. Realizing his situation, he elected to 'stall' the acft into the trees.
