Overview
The accident involved a recently certificated private pilot who, prior to departure, ordered that the aircraft be fueled to capacity. This decision resulted in the aircraft being approximately 90 pounds over its maximum certificated gross weight for takeoff. The departure occurred from a mountain airport where the density altitude was 8,100 feet.
Flight Profile
After takeoff, the aircraft began to climb toward gradually rising terrain. The pilot communicated via radio that he was unable to climb. A witness, the pilot of another aircraft, observed the accident aircraft flying for approximately 5 miles at treetop level. The witness reported that the aircraft exhibited a nose-high attitude with its wings rocking before it impacted treetops and subsequently crashed.
Climb Performance
From the runway to the accident site, the aircraft had climbed approximately 400 feet. The investigation found no evidence of any mechanical discrepancy that could have contributed to the loss of climb performance.
