Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

According to the pilot, during the flight back to the departure airport after practicing aerobatic maneuvers, the engine started to "cut off and on." The pilot decided to make an emergency landing in a field. The airplane impacted trees, and the landing gear and both wings were buckled. The wreckage examination found that both fuel tanks were breached and absent of fuel. The airplane was recovered from the accident site, and an engine test run was conducted. Prior to the test run, all fuel lines leading to the fuel pumps and fuel servo were examined. The mechanical and electrical fuel pumps were checked, and no anomalies were noted. An external fuel tank was plumbed to the mechanical pump for the test run. The fuel-injected engine was started and run for 2 to 3 minutes at various rpms, and no anomalies were noted.

Factual narrative

On May 21, 2020, about 1912 central daylight time, a Bellanca 8KCAB, N68555, was substantially damaged when it was involved in an accident near Rainbow City, Alabama. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, he was practicing aerobatic maneuvers and when finished, he headed back to the departure airport. During the flight back to the airport the engine started to "cut off and on." Although the engine continued to run, it got worse, and the pilot made the decision to make an emergency landing in a field. After touchdown the pilot was unable to stop the airplane in time to avoid an approaching tree line. The airplane impacted trees and came to a stop. The engine was still running after the impact, and the landing gear and both wings were buckled. The wreckage was examined at the accident site by a Federal Aviation Administration inspector. Both fuel tanks were breached and absent of fuel. The airplane was recovered from the accident site for an engine test run attempt. Prior to the test run, all fuel lines leading to the fuel pumps and fuel servo were examined. All of the fuel lines contained trace amounts of fuel and no debris was observed within them. The mechanical and electrical fuel pumps were checked, and no anomalies were noted. An external fuel tank was plumbed to the mechanical pump for the test run. The fuel-injected engine was started and run for 2 to 3 minutes at various rpms; and no anomalies were noted.
