The pilot reported that the takeoff roll and liftoff were normal, however, shortly after becoming airborne he experienced a lower than normal rate of climb. As the airplane approached the end of the field, the pilot turned to the west toward lower terrain in an effort to clear the approaching tree line. The pilot stated that after initiating the turn, the airplane collided with trees and ultimately impacted terrain in an inverted, nose-low attitude. The departure airstrip is approximately 2,000 feet in length and is bordered by large trees. The field elevation is approximately 2,800 feet MSL. No mechanical malfunctions or failures were reported.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
