NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
Because of winds blowing from the south, the pilot made a southerly departure from a mountain airstrip where takeoff to the north is recommended any time wind conditions permit. The pilot departed in a heavily loaded aircraft at a density altitude of about 6,500 feet, but he did not lean the fuel mixture for best power. After departure he encountered downdrafts, and was unable to outclimb the rising forested terrain, and therefore the aircraft eventually impacted the tops of the trees.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to maintain clearance from the rising terrain. Factors include his poor decision to depart without assurance that he could clear the surrounding terrain under the ambient conditions, his failure to adhere to the accepted procedure of leaning the fuel mixture for high-altitude takeoff, high density altitude, downdrafts, mountainous terrain, and tress along his departure path.
