Aircraft Accident/Incident Report

Tucson, Arizona 85741
Sunday, September 16, 2001 7:45 MST

NTSB Narrative Summary Released at Completion of Accident

The airplane entered a dive and impacted a residence during what witnesses reported was a controlled descent. A post crash fire consumed the airplane. The airplane departed a private airpark during a time following the September 11, 2001, terrorist attacks, when VFR general aviation flights were prohibited. The airplane was observed entering a nosedive until it disappeared behind a tree line. The local authorities were told the pilot was having problems with his personal life. The pilot's wife told the local authorities that the pilot had never flown the accident airplane before, and that the airplane hadn't been flown for 5 years. Toxicological tests of samples from the pilot tested positive for prescription antidepressant medications. While the sheriff's department found evidence that the pilot had threatened suicide in the past, neither they nor the medical examiner found evidence to support a suicide by the pilot, and ruled the death as accidental.

NTSB Probable Cause Narrative

the pilot's controlled descent into a residence for undetermined reasons.
