Douglas Cuzzort, Pilot
Gene A. Ahrendt, Forest Service Observer

The fire reconnaissance air patrol plane was flown into a narrow box canyon where the ridges were obscured by clouds and fog. Cuzzort apparently realized the airplane could not climb out of the canyon and attempted to turn around. The canyon was only 1,200 feet wide at this location. The airplane stalled and spun into a steep slope.

  • FS Investigation: Probable Cause

    The probable cause of this mishap was the pilot failing to maintain altitude and airspeed, causing the airplane to stall and enter a spin. The pilot attempted to turn out of the canyon, which was too narrow to accommodate the required radius of turn without stalling the aircraft. The low cloud ceiling did not allow a climb out of the canyon under visual flight conditions. The pilot entered the canyon under conditions that made a safe exit difficult or impossible.

  • Note: Prior to 1996 NTSB did not investigate Gov owned and operated, Gov owned and contractor operated or some aircraft that were privately owned and operated as "public aircraft". Government agency investigations and reports were/are often hard to find and access. The "Pressler Act", passed in 1995 and enacted in 1996, changed that, making all aircraft accident reports easier to access and lessons easier to learn. (Click the link and search on "Pressler".)
