N263R

HISTORY OF FLIGHTOn June 30, 2020, at 1324 Pacific daylight time, an Aviastroitel AC-5M motorglider, N263R, was destroyed when it was involved in an accident near Bend, Oregon. The pilot was fatally injured. The glider was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight.

The pilot was departing in the self-launching motorglider when the accident occurred. A video of the glider’s takeoff roll revealed that the glider’s right wing remained low for much of the takeoff roll. The video did not capture the initial climb or the accident. A witness stated that, once airborne, the glider began to climb rapidly. The glider then banked to the right and entered a “dive” to ground contact. Another witness stated that, shortly after takeoff, the glider “went directly vertical” then banked to the right before diving toward the ground. A postcrash fire ensued and the glider was destroyed. PERSONNEL INFORMATIONThe pilot held a private pilot certificate with ratings for airplane single-engine land and glider. His most recent Federal Aviation Administration (FAA) medical certificate was issued in April 2004, at which time he reported 1,500 total hours of flight experience. The pilot completed the requirements for operation under BasicMed in February 2020. His recent flight experience and his experience in the accident glider make and model was not determined. AIRCRAFT INFORMATIONAccording to FAA records, the glider was originally issued an FAA airworthiness certificate in the Experimental – Exhibition category on October 28, 2002. The glider was then exported to Canada and re-imported to the United States upon purchase by the pilot in February 2018. An FAA airworthiness certificate application completed by the accident pilot around the time of purchase indicated a total airframe time of 26.3 hours. The glider’s total time at the time of the accident could not be determined. AIRPORT INFORMATIONAccording to FAA records, the glider was originally issued an FAA airworthiness certificate in the Experimental – Exhibition category on October 28, 2002. The glider was then exported to Canada and re-imported to the United States upon purchase by the pilot in February 2018. An FAA airworthiness certificate application completed by the accident pilot around the time of purchase indicated a total airframe time of 26.3 hours. The glider’s total time at the time of the accident could not be determined. WRECKAGE AND IMPACT INFORMATIONInformation from local law enforcement indicated that the glider came to rest on airport property near the departure end of the runway. The glider was almost entirely consumed by postimpact fire, except for the left wing. The glider was not examined and was disposed of before examination could take place; therefore, whether any mechanical malfunctions or anomalies contributed to the accident could not be determined. MEDICAL AND PATHOLOGICAL INFORMATIONAn autopsy of the pilot was completed by the Oregon State Medical Examiner’s office, Clackamas, Oregon. According to the autopsy, the pilot’s cause of death was generalized blunt force trauma and the manner of death was accident. The pilot had an implanted pacemaker/defibrillator that was not interrogated. No other significant natural disease was identified.

Toxicology testing by the FAA Forensic Sciences Laboratory detected the antidepressant duloxetine in the pilot’s cavity blood at 45 nanograms per milliliter (ng/mL) and in his liver tissue. The antidepressant amitriptyline and its metabolite nortriptyline were detected in his liver tissue; nortriptyline was also detected in his cavity blood at 699 ng/mL. The non-impairing medications atorvastatin, tamsulosin, and metoprolol were detected in his cavity blood and liver tissue.
