Accident
On February 18, 2010, at approximately 0958 Central Standard Time, N2889D, a Piper PA-28-236 single-engine airplane, was destroyed after the pilot intentionally flew it into the side of an office building in Austin, Texas. The private pilot and an employee who worked in the building were killed. The airplane was registered to and operated by the pilot.
Flight History
The flight originated from Georgetown Municipal Airport (GTU), Georgetown, Texas, at 0944. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight conducted under 14 Code of Federal Regulations Part 91. Preliminary review of air traffic control communications and radar data revealed that after the pilot was cleared for takeoff from Georgetown Airport, he proceeded southbound and climbed to an altitude of 4,800 feet. During this time, a controller approved a radio frequency change and the pilot responded, "Eight niner delta thanks for your help have a great day." No further communications were made with the pilot. At 0954, the airplane was observed on radar descending out of 4,800 feet and making a turn toward the west. At 0957, the airplane was last observed on radar at an altitude of 1,000 feet on a southwesterly heading before the data ended.
Damage
The airplane collided with the office building between the first and second floors, and exploded on impact. The airplane's engine, two (of three) propeller blades, and the right wing came to rest outside of the building. The empennage came to rest on the ledge of the building and was partially hanging over the edge. The left wing, portions of the fuselage, and a propeller blade were found inside the building on the second floor. The flaps were found in the fully retracted position. The airplane was destroyed by impact and the post-impact fire.
Weather
The weather at Austin Bergstrom International Airport (AUS), Austin, Texas, at 0953, was reported as calm wind, visibility 10 miles, few clouds at 25,000 feet, temperature 9 degrees Celsius, dew point 1 degree Celsius, and a barometric pressure setting of 30.24 inches of mercury.
Investigation
As this event was an intentional act, the FBI has assumed jurisdiction and control of the investigation.
