What happened
During a daytime local training mission, an unidentified twin engine aircraft departed from Wright-Patterson Air Force Base. While the crew was performing the approach phase of the flight, the aircraft became uncontrollable. The plane descended into a residential area at 1843 Tuttle Avenue in East Dayton, impacting several homes.
The collision resulted in a fire that destroyed at least four houses. The accident resulted in four fatalities, including both members of the flight crew and two individuals who were on the ground at the time of the impact.
Findings
An investigation into the crash determined that the primary cause was a mechanical failure involving an engine component. Specifically, a loose engine cowling shifted forward and struck the propeller during flight.
