American Eagle Flight 4184 was a scheduled flight from Indianapolis International Airport to Chicago O'Hare International Airport. On October 31, 1994, the Embraer EMB 120 Brasilia aircraft encountered severe weather conditions, including freezing rain and low visibility, as it approached Roselawn, Indiana. The flight, operated by American Eagle Airlines, reported icing on its wings, which prompted a loss of control shortly before the crash. The aircraft went down in a field about a mile from the Roselawn airport, killing all 68 passengers and crew members aboard.

The National Transportation Safety Board (NTSB) conducted an extensive investigation into the incident, discovering that the aircraft had not been adequately de-iced before takeoff. Additionally, the NTSB highlighted the dangerous effects of winter weather on smaller aircraft operations, including the need for more stringent safety protocols for severe weather conditions. The resulting report led to changes in regulations for icing procedures and training for pilots about winter weather hazards.

This tragic crash raised awareness about aviation safety issues, particularly concerning regional flights and the effects of ice on aircraft performance. The incident underscored the complexity of flying in adverse weather and prompted the aviation industry to reevaluate safety measures and ensure better preparedness for winter operations.
