At 1327 Mountain time, the airplane was destroyed and its solo ATP-rated pilot fatally injured upon impact with terrain 500 feet west of Runway 20 at the Santa Fe (N.M.) Municipal Airport. Visual conditions prevailed for the aerobatic flight, which was the second performance in the 2004 Santa Fe Air Show. An FAA inspector witnessing the airshow later reported that the airplane was high, at approximately 1500 feet AGL, when it entered an inverted spin. The inspector said, The pilot attempted to recover but didnt make it. The airplane struck flat in an upright, nose down attitude and was engulfed in a fireball. A witness, one of the air shows performers, said the pilot was performing a torque roll. The witness said he saw the airplane come out the bottom of the smoke and enter an inverted flat spin. The witness said he saw the airplane make three revolutions. The witness said he thought the pilot had gone too far. He came off the throttle, the rotation stopped, then the airplane yawed. I heard the engine come in. The airplane came around in a positive attitude. He was getting low. He was upright in a spin. He went to full power. He made a turn and a half and then hit [the ground].
