The Worst Single Aircraft Accident in American History: American Airlines Flight 191

On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC-10, crashed shortly after takeoff from Chicago’s O’Hare International Airport, killing all 271 people on board and two people on the ground. It remains the deadliest single-aircraft accident in American history.

The Events Leading Up to the Crash

The flight was scheduled to depart from Chicago to Los Angeles. During the pre-flight inspection, mechanics noticed a problem with the left engine. They attempted to fix the issue, but ultimately replaced the engine with a spare. However, during the replacement process, a critical hydraulic line was accidentally disconnected. The line was responsible for controlling the aircraft’s left wing, and without it, the wing could not be properly controlled.

As the plane took off, the disconnected hydraulic line caused the left wing to lose lift and stall. The pilots struggled to regain control, but the plane ultimately crashed into a field near the airport. The impact was so severe that the aircraft disintegrated into pieces.

The Investigation and Its Findings

The National Transportation Safety Board (NTSB) investigated the crash and determined that the primary cause was the failure of American Airlines to properly maintain the aircraft and the mechanics’ failure to properly reconnect the hydraulic line. The investigation also revealed that there were design flaws in the DC-10’s wing design, which made it more susceptible to stalling.

The NTSB also found that the pilots had not received adequate training on how to handle a wing stall. The pilots’ lack of experience and training contributed to their inability to regain control of the aircraft.

The Aftermath and Legacy

The crash of American Airlines Flight 191 had a profound impact on the aviation industry. It led to a number of safety improvements, including:

• Improved maintenance procedures for aircraft
• Increased training for pilots on how to handle wing stalls
• Design changes to the DC-10’s wing to make it more stable

The crash also led to a renewed focus on aviation safety. The NTSB’s investigation highlighted the importance of proper maintenance, pilot training, and aircraft design in preventing accidents. The crash remains a stark reminder of the importance of safety in the aviation industry.

The Impact of the Crash

The crash of American Airlines Flight 191 had a devastating impact on the families of the victims. It also led to a significant loss of life and property. The crash also had a major economic impact on the airline industry, as it resulted in a drop in passenger confidence and a decrease in travel.

Conclusion

The crash of American Airlines Flight 191 is a tragedy that should never be forgotten. The accident serves as a reminder of the importance of safety in the aviation industry and the need for constant vigilance to prevent such tragedies from happening again.
