Analysis

The flight instructor reported that, while conducting mountain flying training, and using roads as a primary means of navigation, the pilot rated student made a wrong turn due to smoke/haze and entered an area where the airplane could not out climb terrain. The flight instructor assumed control of the airplane which subsequently collided with vegetation (trees). The airplane sustained substantial damage to both wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
