Prop Design Causes Air Crash  – Episode 122

A close look at the crash of Atlantic Southeast Airlines Flight 2311. This 1991 accident brings focus to the importance of thorough and methodical inspection and maintenance beginning in the factory.

The flight started at Hartsfield–Jackson Atlanta International Airport and was headed to Brunswick, Georgia. The twin-turboprop Embraer EMB 120 Brasilia crashed just north of Brunswick while approaching the airport for landing. All 23 people aboard the plane were killed, including passengers NASA Astronaut Sonny Carter and former United States Senator John Tower.

The NTSB determined the cause was the design of the propeller. As the crew pulled the power back, the prop went to a position below flight idle, creating a wall that dramatically slowed the plane.

Hear details on the dynamics that led to the loss of control with insight only Greg and John can provide. They also dissect the certification process for airplane components that is supposed to ensure safety.

Many of the issues with certification discussed following the 737 Max crashes have parallels to the findings of this crash.
