Probable cause

The pilot's loss of control attempting to recover from a low-level aerobatic maneuver. Contributing to the accident was the pilot's decision to attempt the low-level maneuver which significantly reduced any margin for error.

NTSB narrative

The private pilot and a passenger were conducting a local flight and performing aerobatics. Witnesses observed the pilot conducting "flybys" and "tricks" in the area. One witness reported observing the airplane complete "flips and spins" for about 10 minutes before the accident. Ground-based video footage depicted the airplane flying over the river at low altitude. The airplane pitched up and entered a steep climb. As the airplane reached the top of the climb, it yawed to the left and entered a near- vertical descent and gradual left turn. Shortly before impacting the river, the gradual left turn reversed abruptly into a right, descending turn. The airplane then impacted the river. A post-accident examination of the airframe and engine did not reveal any anomalies consistent with a pre-impact failure or malfunction. According to a friend, the pilot was competent in spins and had received instruction in aerobatic maneuvers. However, the lack of a formal logbook training record with respect to aerobatics, the investigation could not determine the pilot's level of proficiency in such maneuvers. Toxicological testing on the pilot was positive for cocaine and its metabolites; cocaethylene, a metabolite formed when cocaine is ingested with alcohol; and levamisole, a drug commonly used to "cut" street cocaine, in urine. Cavity blood was positive for methamphetamine and its metabolites. The absence of cocaine in the pilot's blood suggested distant usage. Accordingly, the acute effects of the drug had likely dissipated. The level of methamphetamine in the pilot's blood sample was low. As a result, the presence of any residual effects of the drug could not be determined. Based on the available information, the investigation was unable to determine whether the pilot was impaired, if at all, at the time of the accident.
