HISTORY OF FLIGHT On July 6, 2019, about 1330 central daylight time, a Grob G103 glider, N106NS, was substantially damaged when it was involved in an accident near Brandon, Mississippi. The pilot was fatally injured. The glider was registered to and operated by the Central Mississippi Soaring Society, LLC. Visual meteorological conditions prevailed, and no flight plan was filed for the Title 14 Code of Federal Regulations Part 91 personal flight. The flight originated from the Woodbridge Airport (6MS1), Brandon, Mississippi, about 1315, and was en route to the Harrell Field Airport (MS08), Pisgah, Mississippi.
According to the towpilot, the purpose was to move two gliders from 6MS1 to MS08, about 6 nautical miles west of MS08, from where they hangered the gliders, to where they conducted their flights. The towpilot towed the first glider to 2,000 ft above ground level (agl) southeast of 6MS1, where the glider released from the towplane. The towpilot then returned to 6MS1 for the accident glider. The accident pilot stated to the towpilot that he planned to release at 3,000 ft agl.
The towpilot added that the second tow was slow due to the glider's weight and the high density altitude at the time but was "uneventful." At an altitude of about 2,100 ft agl, the glider released from the towplane. The towpilot stated that this was in the same area that the first glider released, and the accident pilot conducted the "normal right turn" after releasing. The towpilot reported that he did not see the accident glider or hear from the accident pilot following release.
The pilot in the first glider reported that he heard the accident pilot state over the radio that he was "getting low and would probably have to land out." The wreckage was located in a fenced field about 2.5 miles southeast of 6MS1 and about 6 miles southwest of MS08. WRECKAGE AND IMPACT INFORMATIONThe glider came to rest inverted about 150 ft beyond an oak tree located at the edge of a field. There were several wire fences across and lengthwise to the field.

A piece of the glider's right wing skin was found in a branch of the oak tree, about 25 to 30 ft up from the ground. Several small branches and leaves were located on the ground just beneath the branch. Additionally, there were several impact signatures on parts of the tree branch near the wing skin; the signatures and ground scars are consistent with the glider colliding with the tree before the impact with terrain. The glider was examined on site and all major components were accounted for at the scene. Control continuity was established to the respective control surfaces.
No pre-impact anomalies were noted during the airframe examination.
MEDICAL AND PATHOLOGICAL INFORMATIONThe Mississippi State Medical Examiner's Office, Pearl, Mississippi, conducted an autopsy on the pilot. The autopsy noted the cause of death was determined to be "blunt force trauma."
The Federal Aviation Administration Forensic Sciences Laboratory, Oklahoma City, Oklahoma, conducted toxicological testing. The specimens were not tested for cyanide. The test was negative for ethanol and carbon monoxide. The test was positive for Salicylate, Losartan and Carboxy-Delta-9-Tetrahydrocannabinol and 11 hydroxy-Delta-9-Tetrahydrocannabinol (THC-OH), the inactive and active metabolites, respectively, of tetrahydrocannabinol, the primary psychoactive component of marijuana, were detected in urine but not in blood..
