HISTORY OF FLIGHTOn April 13, 2021, about 0852 eastern daylight time, a Cessna A188B, N4912Q, was destroyed when it was involved in an accident near Pineview, Georgia. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 137 aerial application flight. The airplane was based at a private airstrip in Unadilla, Georgia. According to the operator, the airplane departed Unadilla about 0705 with about 2 hours 30 minutes of fuel onboard. The pilot was spraying for mosquitos when the airplane collided with powerlines. At the time, he had two more residences to spray before returning to the airstrip. WRECKAGE AND IMPACT INFORMATIONThe wreckage was located inverted, about 8 miles southeast of the departure airstrip, in a field near powerlines. The powerlines were about 50 ft above ground level and damage to the powerlines and landing gear were consistent with both main landing gear contacting the powerlines in a west-to-east direction. Both main landing gear separated during impact with the powerlines, and the propeller and lower engine cowling also exhibited damage from contact with the powerlines. The powerlines were approximately 1.25 inches thick, consisting of a steel core with aluminum wires twisted around the core. Flight control continuity was established to the ailerons, elevator, and rudder. All flight control surfaces remained attached to the structure. The manual flap handle was in an extended position. The pilot’s seat was fitted with a three-point safety harness. The webbings remained intact and were cut by first responders. The buckle remained fastened. The engine’s crankshaft was rotated by hand at the propeller, which remained attached to the crankshaft; suction and compression were observed on all cylinders and no internal binding was observed. One propeller blade was bent forward 180° at midspan and then bent aft at the tip. The other blade was twisted. Both blades exhibited leading edge polishing/grinding along the outboard one-third of each blade. ADDITIONAL INFORMATIONData downloaded from an onboard GPS revealed that the airplane was on a northeasterly track toward the powerlines. The last position recorded was at 0852:43, about 3/4-mile southwest of the accident site, indicating a groundspeed of 116 mph and a GPS altitude of 327 ft. The elevation at the accident site was 315 ft mean sea level. The sectional aeronautical chart that covered the area of the accident depicted the powerlines struck by the airplane. Solar calculations for the location and time of accident revealed that the sun was approximately 23° above the horizon and 50° to the right of the airplane’s track. MEDICAL AND PATHOLOGICAL INFORMATIONAn autopsy was performed on the pilot by the Georgia Division of Forensic Sciences. The cause of death was multiple blunt force trauma. Toxicology testing was performed by the FAA’s Forensic Sciences Laboratory. The results were negative for alcohol and other drugs.
