Accident Overview
A pilot conducting an aerial application flight in rolling hills within a canyon reported that canyon wind forced the airplane to the ground. The aircraft impacted terrain, after which the pilot egressed from the cockpit without further incident. A postcrash fire ensued, completely destroying the airplane.
Pilot Report
The pilot stated that there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The cause of the forced landing was attributed solely to the wind conditions encountered in the canyon.
Postcrash Fire
Following the impact with terrain, a fire erupted and consumed the aircraft. The pilot successfully exited the cockpit prior to the fire spreading, sustaining no reported injuries. The aircraft was declared a total loss due to the fire.
Additional Information: Mountain Flight Operations
The Federal Aviation Administration has published FAA-P-8740-60, *Tips on Mountain Flying*, which provides guidance on safe operations in mountainous areas. The publication notes that strong winds can create dangerous conditions, including turbulence and strong updrafts and downdrafts. It advises that mountain flying should not be attempted if winds aloft at mountain top levels exceed 25 knots, as potentially hazardous conditions are likely above that threshold.
