The airplane impacted terrain at about 1210 Pacific time while maneuvering and was destroyed. The pilot and one passenger were killed. Visual conditions prevailed. According to a witness, he saw the accident airplane at about 2000 feet, and reported hearing “throttle adjustments,” the sound of an “engine surging.” The airplane performed an “aerobatic maneuver,” which he described as a “flip,” followed by a loop, and then the airplane stalled. The witness reported that the airplane was losing altitude, and descended behind the treeline; he then heard the airplane impact the ground. He stated that the whole event lasted about 15 seconds.
