An FBI pilot, along with two other special agents in separate airplanes, was receiving agency-sponsored mountain flying instruction. His instructor announced that they were going to practice box canyon turnarounds. Shortly thereafter, white smoke was seen coming from the side of the mountain. Evidence indicates the airplane struck tree tops while in a steep left descending turn in what was described as an extremely tight box canyon.
Probable Cause: The flight instructor's improper inflight decision to enter a narrow blind/box canyon, and his misjudgment of the vertical and lateral clearances. A factor was the downdrafts.
