Tragic Incidents: A Closer Look at the Worst 737 Crashes

Let's get into the specifics of some of the most harrowing events. These are the incidents that sent shockwaves through the aviation community and led to significant changes. It's important to remember the lives lost in these tragedies and the families forever affected.

United Airlines Flight 585 (1991)

This was a truly baffling incident that occurred on March 3, 1991. United Airlines Flight 585, a Boeing 737-200, was on a routine flight from Denver to Colorado Springs. During its approach to the runway, the aircraft suddenly went into an uncontrollable roll and plunged to the ground, killing all 25 people on board. What made this crash particularly perplexing was the lack of any distress calls or apparent pilot struggle in the final moments. The investigation that followed was extensive and painstaking. Initially, many theories were explored, but the focus eventually landed on a critical component: the rudder control system. The investigators discovered that a power-transfer unit (PTU) within the rudder system could, under certain circumstances, become jammed, causing the rudder to move to an extreme position without pilot input. This could lead to a loss of control, especially during low-speed flight phases like landing. The National Transportation Safety Board (NTSB) concluded that this rudder malfunction was the probable cause. This finding was monumental because it identified a specific mechanical issue within the 737's design that had never been anticipated. The implications were huge, leading to modifications of the rudder system across all 737 variants in service. This incident is a stark reminder that even seemingly minor components can have catastrophic consequences if they fail in an unexpected way. It highlighted the importance of understanding not just how systems are supposed to work, but how they might fail under pressure and how those failures could cascade. The worst 737 crashes like this one force engineers and safety experts to think outside the box, anticipating failures that are statistically improbable but incredibly dangerous. The lessons learned from Flight 585 were critical in preventing future incidents related to the rudder system. The industry's response was swift, with inspections and modifications implemented worldwide, showcasing a commitment to learning from tragedy and enhancing safety for all. It’s a testament to the dedication of investigators and engineers that such a complex issue was eventually pinpointed and rectified, making the skies safer for us all.

USAir Flight 427 (1994)

Just three years after the United Airlines Flight 585 incident, a chillingly similar tragedy struck. USAir Flight 427, another Boeing 737-300, was on approach to Pittsburgh International Airport on September 8, 1994. Like Flight 585, the aircraft suddenly banked sharply to the left, entered an uncontrollable dive, and crashed, killing all 132 people on board. The similarity to the United 585 crash was undeniable, and investigators immediately suspected a common cause. This led to an unprecedented level of scrutiny on the 737's rudder system. The investigation into USAir Flight 427 was one of the most complex and protracted in NTSB history. It involved re-examining all the evidence from Flight 585, conducting extensive simulator testing, and analyzing countless hours of flight data. The findings ultimately corroborated the conclusion from the Flight 585 investigation: a faulty rudder servo valve within the same power-transfer unit (PTU) was the culprit. It was determined that the valve could inadvertently get stuck in a position, causing the rudder to move uncontrollably. This was particularly dangerous during the critical landing phase when the aircraft is flying at lower speeds, making it more susceptible to sudden control surface movements. The NTSB's final report confirmed that a combination of a stuck valve and the pilots' inability to counteract the powerful, unexpected rudder deflection led to the loss of control. This second catastrophic event involving the same aircraft type and a similar flight profile cemented the urgency for a global fix. The NTSB issued a series of safety recommendations, including modifications to the rudder system's design and enhancements to pilot training for handling such emergencies. The worst 737 crashes like Flight 427 are devastating, but they also serve as a powerful catalyst for change. The industry's response was decisive. Boeing worked with regulatory authorities to implement design changes to the rudder system, and airlines retrained their pilots on procedures for dealing with unexpected rudder inputs. This dual tragedy underscored the interconnectedness of safety systems and the critical need for vigilance. It’s a testament to the perseverance of investigators that they were able to solve this complex puzzle, and the implementation of corrective actions has undoubtedly saved countless lives since.

Turkish Airlines Flight 1951 (2009)

This incident, which occurred on February 25, 2009, involved a relatively new Boeing 737-800 operated by Turkish Airlines. Flight 1951 was en route from Istanbul to Amsterdam when it crashed just short of the runway at Amsterdam Schiphol Airport. Of the 135 people on board, nine tragically lost their lives, and many others were injured. This was not a case of a sudden, uncontrollable maneuver, but rather a more gradual loss of control during the final approach. The investigation revealed that the aircraft's radio altimeter had provided incorrect altitude readings to the autothrottle system. The autothrottle, designed to maintain a specific airspeed, interpreted the faulty low altitude readings as a signal to drastically reduce engine power, essentially causing the plane to stall. The pilots, unaware of the erroneous altitude data, were struggling to maintain airspeed and altitude, and the drastic power reduction exacerbated the situation. The primary issue identified was a design flaw in the autothrottle system's logic when confronted with conflicting or erroneous data from the radio altimeter. The system lacked sufficient redundancy and cross-checking mechanisms to detect and override such a critical error. The investigators concluded that the combination of the incorrect altitude information and the autothrottle's inappropriate response led to the loss of airspeed and subsequent stall. This incident was a wake-up call regarding the complexities of automated flight systems and their reliance on accurate sensor data. It highlighted the need for more robust error-detection protocols within these sophisticated systems. The worst 737 crashes like this one emphasize that even with advanced technology, human oversight and system integrity are paramount. Following the investigation, Boeing and other manufacturers implemented software updates and revised operating procedures for the autothrottle and altimeter systems. Pilot training was also updated to better prepare them for scenarios involving faulty instrument readings and to emphasize manual flying skills during critical phases of flight. The lessons learned here are about the critical interdependence of various aircraft systems and the absolute necessity for cross-validation of critical data, especially when automation is involved. It’s a reminder that technology is a tool, and like any tool, it needs to be used and managed with the utmost care and understanding.

Lion Air Flight 610 (2018) & Ethiopian Airlines Flight 302 (2018)

These two crashes, occurring within months of each other, brought the Boeing 737 MAX into the global spotlight for all the wrong reasons. Lion Air Flight 610 crashed into the Java Sea on October 29, 2018, just minutes after takeoff from Jakarta, killing all 189 people on board. Then, on March 10, 2019, Ethiopian Airlines Flight 302 crashed near Addis Ababa, killing all 157 people on board. Both flights involved the brand-new Boeing 737 MAX 8 aircraft, and chillingly, both experienced similar flight control problems shortly after takeoff. The common culprit in both these horrific tragedies was a new flight control software system called the Maneuvering Characteristics Augmentation System (MCAS). MCAS was designed to prevent the MAX from stalling by automatically pushing the nose down if it detected a high angle of attack. However, in both accidents, a single faulty sensor reading from an
