Not Much New In NTSB Report On Austin Plane Attack

The National Transportation Safety Board has released its final report into the attack on an IRS building launched earlier this year by Joe Stack, a man believed to be frustrated with the federal government.

As we reported on KUT, Stack flew a single-engine airplane into a seven-story office building that housed about 200 IRS employees on February 18. The crash killed Stack and IRS employee Vernon Hunter, whose funeral attracted hundreds of people.

The NTSB report reveals Stack's last recorded words were, "Have a great day," a comment he made to an air traffic controller.

Here's the narrative from the report. You view and download the full five-page document here.

On February 18, 2010, 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. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight conducted under 14 Code of Federal Regulations Part 91. The flight originated from the Georgetown Municipal Airport (GTU), Georgetown, Texas, at 0944.

Preliminary review of air traffic control communications and radar data revealed that after the pilot was cleared for take off 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.

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.

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. As this event was an intentional act, the FBI has assumed jurisdiction and control of the investigation.
