On October 15, 1960, a Curtiss C-46 Commando (registration N1300N) operated by Capitol Airways was involved in an aviation accident near Plain City, United States of America during landing or approach. 2 people were killed. Investigators recorded the probable cause as: The fatigue of bolts in the lower attach angle of the right wing caused an in-flight structural failure. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.
A fatal aircraft accident occurred near Plain City, Utah, when a plane lost control during its approach to the airbase.
What happened
During an approach to Ogden-Hill Air Force Base, an aircraft flying at approximately 6,500 feet experienced a sudden loss of control. The aircraft entered a steep dive and struck the ground in a field situated in Plain City, which is roughly 10 miles away from the military installation.
The impact resulted in the total destruction of the aircraft. There were two fatalities among the crew members on board.
Findings
Investigations into the accident determined that the crash was caused by the failure of the lower attach angle bolts on the right wing. This structural failure led to a loss of aerodynamic stability during the flight.
Probable cause
The fatigue of bolts in the lower attach angle of the right wing caused an in-flight structural failure.
