The Fateful Flight of American Airlines Flight 1572: A Tale of Errors and Survival
On November 12, 1995, American Airlines Flight 1572, an MD-83, embarked on a troubled journey from Chicago's O'Hare Airport to Bradley International Airport in Connecticut. With 73 passengers and five crew members on board, this flight would soon become a harrowing example of how multiple factors can converge to create a perfect storm of aviation disaster.
With the eastern United States experiencing severe weather, the flight took off nearly two hours late at 11:05 PM. The captain, Kenneth Lee, a veteran pilot with over 8,000 flying hours, and the first officer, John Richards, with 5,000 hours, faced an immediate challenge as they ascended into turbulent skies. The situation worsened when the air traffic control tower at Bradley was evacuated, leaving a solitary supervisor behind who was unaccustomed to manning the controls.
As the flight descended toward Bradley, a small mistake from earlier in the day began to unravel. The pilots slipped below their minimum descent altitude during a challenging approach, battling pouring rain and high winds. Almost every possible error occurred: miscommunication regarding altimeter settings, a lack of current weather data, and a quickened descent that put the aircraft dangerously low.
The Approach and Critical Errors
Descending from 33,000 feet, the crew received weather updates indicating worsening conditions at Bradley, including gusting winds and rapidly falling atmospheric pressure. The pilots mismanaged updates regarding the altimeter settings, with one pilot mistakenly recalling the old setting rather than adjusting to the new, agreed-upon pressure.
Despite warnings of severe turbulence—characterized as forces strong enough to cause loss of control—the flight crew continued their descent, risking a catastrophic event. The two pilots mistakenly believed they were complying with their minimum descent altitude—an altitude critical for safety when approaching an airport during inclement weather.
As they began their final approach at around 1:00 AM, the aircraft was at 1,000 feet, facing severe wind shear conditions that further complicated matters. Unfortunately, they did not receive a key update on atmospheric pressure that would have informed them of their actual altitude, which was falling below safe limits.
At 1:03 AM, approaching the airport, the first officer noted that they were descending below the minimum altitude. The captain, however, triggered the altitude hold button on the autopilot instead of pulling up—leading the aircraft to continue its rapid descent.
Just four seconds after the warning, Flight 1572 struck treetops, with the plane traveling at over 250 kilometers per hour. As chaos ensued within the cockpit, the crew quickly shifted focus to regain control and prepare for an emergency landing, calling for maximum thrust to regain altitude, albeit unsuccessfully.
Miraculously, despite severe damage to the aircraft, Captain Lee managed to land on the runway just two and a half miles from the airport. The impact was intense, but all aboard survived, with only one minor injury reported.
Investigation and Lessons Learned
The National Transportation Safety Board (NTSB) launched an investigation that identified several key factors contributing to the incident. The most glaring issue was the failure to maintain minimum descent altitude; both pilots should have focused on instrument checks instead of visually searching for the airport during their approach.
The NTSB report highlighted the importance of clear communication regarding altimeter settings and indicated that a timely update on atmospheric pressure could have significantly altered the aircraft's altitude readings, keeping them safely above the trees.
Despite the critical errors made leading to the near disaster, the report praised the crew for their management during the emergency, recognizing their decision-making and teamwork in averting a potential catastrophe after the impact.
Conclusions
The incident involving American Airlines Flight 1572 serves as a stark reminder of the complexities of aviation safety. It underscores the necessity of maintaining strict adherence to regulations concerning altimeter settings, communication protocols, and safety measures during an approach.
Following the incident, the aviation industry took significant steps to reassess procedures and improve training for flight crews on effective cockpit resource management and decision-making under duress.
While the aircraft suffered damages amounting to nine million dollars, it was effectively repaired and continued to serve until its retirement in 2017. The legacy of Flight 1572 continues to offer valuable lessons in the ongoing pursuit of air travel safety.
