On May 16, 2019, about 1435 central daylight time, an experimental, amateur-built Zenith CH750 STOL, N750GZ, was substantially damaged when it impacted terrain during a forced landing near Savannah-Hardin County Airport (SNH), Savannah, Tennessee. The sport pilot and passenger were not injured. The airplane was privately owned and operated under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan was filed for the local personal flight, which departed SNH about 1420.

According to the pilot, he performed a preflight inspection of the airplane at 1400 with no anomalies noted. He stated that he checked the battery voltage after engine start-up then he departed SNH. While in-flight he observed a drop in the direct current (DC) electrical bus voltage from a normal value of about 13.6 volts direct current (vdc) to about 12.5 vdc. He initiated a turn back to SNH and about 2 minutes later, the DC bus voltage dropped to 0 vdc and the engine stopped producing power. The pilot selected an open field and preformed a forced landing. After the accident, the pilot noted that the in-line circuit breaker located under the instrument panel from the alternator was tripped.

According to Federal Aviation Administration (FAA) airman records, the pilot held a private pilot certificate with a rating for airplane, single engine land. He reported 251.4 total hours of flight experience, which included 58.7 hours of flight experience in the accident airplane.
