Analysis

The pilot of the tailwheel equipped airplane reported that, during short final, just before he initiated a landing flare, he lost sight of the dirt airstrip and initiated a go around. Shortly after, the pilot turned right, but he quickly realized that he would not be able to outclimb several treetops, so he lowered the nose attitude. Subsequently, the right wing struck a tree, the airplane impacted the ground at a steep angle and came to rest inverted. The airplane's wings and fuselage were substantially damaged.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain clearance from trees during a go-around, which resulted in an impact with terrain. 

Findings

Personnel issues Monitoring environment - Pilot
Aircraft Altitude - Not attained/maintained
Environmental issues Tree(s) - Effect on operation

  2. Any helicopter service that does construction lifts can ferry it out. Won't be cheap. Probably ought to consider the recovery aspects before landing in remote areas.
