What happened
Witnesses at the scene observed the aircraft flying overhead before it entered a sharp left turn, which was followed by a left tailspin. One witness reported that the aircraft made a sharp turn and descended straight down. Another observer noted that the airplane completed two full circles, described as "loopty loops," but could not specify the direction of the turns. This witness further observed that during a third circle, the aircraft was at too low an altitude to recover.
The owner of the aircraft suggested that the pilot may have been circling her brother's residence, which is located near the accident site.
Findings
An investigation into the circumstances of the crash included toxicological testing of the pilot conducted at the FAA Toxicology Accident Research Laboratory. The toxicology report confirmed that 0.187 (ug/ml, ug/g) of cocaine was detected in the pilot's blood. Additionally, it was noted that the aircraft was not equipped with a stall warning system.
