Probable cause
The pilot-in-command/cfi's performance of a low altitude aerobatic maneuver from which he failed to recover. Factors which contributed to the accident related to the pic's improper inflight decision, poor judgment, and his psychological condition.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
Airline captain took a 414-hour private pilot for an airplane ride during which a series of low level aerobatic maneuvers were performed. Witnesses described the maneuvers as being wing overs and/or loops, and they were performed at progressively lower altitudes. The pilot(s) failed to pull out of the final maneuver, and the dual control airplane impacted the field while in a wings level and a 60 degree nose low attitude. The investigation revealed evidence of stressful events in the pilot's professional and personal life. Also, cannabinoid metabolite was found in his urine.
