Incident Overview
Four witnesses reported observing the aircraft taxi to the departure end of runway 28 and pause for what they considered sufficient time to conduct engine and flight control checks. During the takeoff roll, the aircraft lifted off near the midpoint of the 7,000-foot runway and initiated a shallow climb.
Witness Observations
As the aircraft neared the departure end of the runway at an estimated altitude of 100 to 150 feet above ground level, witnesses saw it begin a left turn and rapidly lose altitude. The descent continued throughout the turn until the aircraft struck the ground.
Postcrash Investigation
Examination of the wreckage revealed no preexisting malfunctions in the flight controls, fuel system, or engine. Toxicological analysis of the pilot showed no evidence of impairment.
Environmental Conditions
The flight departed to the west at dusk, with a favorable visual horizon provided by the setting sun. However, as the aircraft turned left, the forward visual horizon became increasingly indistinct due to diminishing daylight and scarce ground lighting. At the time of takeoff, the density altitude was approximately 7,800 feet mean sea level.
