Accident Overview

A student pilot departed early in the morning and was not found until the following afternoon. There were no witnesses to the accident.

Impact Evidence

The aircraft impacted the ground in a 50-degree nose-down attitude at a high rate of speed. Evidence indicated that the aircraft was rotating around its longitudinal axis at the time of impact.

Toxicology Results

A toxicological examination revealed the presence of a therapeutic level of diazepam (0.2 µg/mL) in the pilot's blood. Additionally, 56 ng/mL of marijuana metabolite were found in the urine, and 27 ng/mL of 9-carboxy-THC (the principal metabolite of tetrahydrocannabinol, the principal psychoactive constituent of marijuana) were found in the pilot's blood. The detected concentration of marijuana metabolite in blood is associated with marijuana use within the prior half day. The combination of diazepam and recent marijuana use may result in an additive extent of impairment.
