Analysis

Shortly after takeoff the airplane collided with trees and rising terrain. In a written statement the pilot reported the airplane collided with trees and rising terrain after departing runway 12. He reported that the airplane cleared trees (approximately 50 feet in height) located at the end of the departure runway, however, the aircraft made contact with multiple trees and rising terrain beyond the departure end of the runway. The pilot stated "we hit trees for 150 yards before slowing enough to hit the ground." The published airport elevation for Benchmark is 5,434 feet MSL. No mechanical malfunctions or failures that may have contributed to the accident were reported.
