## Preliminary report

On August 15, 2025, about 1910 eastern daylight time, a Grumman American Avn. Corp. G-164-B airplane, N7015N, was substantially damaged when it was involved in an accident near Fowler, Indiana. The pilot was not injured. The airplane was operated under Title 14 Code of Federal Regulations Part 137 as an aerial application flight. According to the pilot, he departed a private airstrip just north of Sheldon, Illinois, earlier that day and had been flying for about 5 hours, stopping a few times for fuel and aerial application product. He was on his last spray run of the day when the engine suddenly stopped. The pilot advanced the throttle, but there was no response from the engine. He landed the airplane in a bean field. The wings and fuselage sustained substantial damage. The pilot estimated that he had about 60 gallons of fuel on board at the time of the accident. The engine was overhauled 6 weeks before the accident and had accumulated about 155 hours. A postaccident examination revealed that the sensing line for the fuel control unit was severed. The airplane was retained for further examination.
