On July 29, 2016, about 0915 central daylight time, an Air Tractor AT-402 airplane, N1016G, impacted power lines and terrain near Sac City, Iowa. The commercial rated pilot was fatally injured and the airplane was destroyed. The airplane was registered to and operated by a private individual under the provisions of 14 Code of Federal Regulations Part 137 as an aerial application flight. Visual meteorological conditions prevailed at the time of the accident and the flight was not operated on a flight plan. The airplane departed Arthur N Neu Airport (CIN), Carroll, Iowa, about 0900 and was spraying in the area of Sac City Municipal Airport, (SKI), Sac City, Iowa. 

The responding Federal Aviation Administration (FAA) inspector reported that the airplane impacted a corn field one mile south of SKI. Static power lines were found downed near the accident site. 

At 0915, the automated weather observation at Storm Lake Municipal Airport (SLB) Storm Lake, Iowa, located about 18 miles northwest of the accident site recorded wind from 030 degrees at 6 knots, 10 miles visibility, clear sky, temperature 20 degrees C, dew point 16 degrees C, and altimeter 30.09 inches of mercury.

The Sac County Sheriff’s Office and the Federal Aviation Administration are continuing to investigate a fatal plane crash that occurred Friday morning, July 29.  

At approximately 9:48 a.m., Raccoon Valley Electric Cooperative crews responded to reports of a power outage in the 2900 block of Sierra Ave., three and half miles south of Sac City, and discovered the wreckage of a crop dusting aircraft and the body of the pilot, 44-year-old Mark James Watson of Burlington. 

It appears, from results of the preliminary investigation, that Watson clipped a static line on the high-voltage power lines owned by MidAmercan Energy. This caused the Air Tractor Inc AT-402 plane to crash into the field owned by Steve Hansen of Sac City. 

Watson had recently refueled with 160 gallons of fuel and reloaded with 300 gallons of chemical at the Carroll airport.

 Region 5 Hazmat of the Fort Dodge Fire Department, the Sac City Fire Department and Sac County Emergency Medical Services assisted at the scene. 

Watson’s body has been sent to the State Medical Examiner’s office in Ankeny for autopsy. 

The Iowa Department of Natural Resources will continue to monitor the crash site where the fuel and chemicals were absorbed.
