Accident Sequence
The pilot departed Runway 27 with a left crosswind, heading south toward higher terrain. The airplane followed a slower single-engine aircraft that had departed before it. According to ground witnesses, as the airplane approached the higher terrain, it entered a left banking turn. During the turn, the wings oscillated rapidly, and the airplane subsequently stalled. It crashed into the center divider of California State Highway 395, which runs adjacent to and parallel with the east-west runway.
Examination Findings
A post-accident examination of the airframe and engine revealed no evidence of any preexisting malfunctions or failures. However, the investigation determined that the airplane had exceeded its maximum gross takeoff weight and was operating near its aft center of gravity limits.
Pilot Medical Background
Prior to the accident, the pilot had complained to his doctor about episodes of forgetfulness and confusion. The doctor recommended that the pilot cease any flying activities until the medical condition could be diagnosed and treated. The pilot did not follow this advice.
