The psychological well-being of flight crew became a significant focus following this disaster.
LaMia Flight 2933 - November 28, 2016
A chartered aircraft carrying the Brazilian Chapecoense football team, along with journalists and crew, crashed near Medellín, Colombia. The Avro RJ85 aircraft ran out of fuel due to inadequate flight planning and fuel management. Of the 77 people on board, only six survived. This crash highlighted critical issues in airline operational oversight, particularly concerning charter flights and the responsibility of airlines to ensure adequate fuel reserves for the planned route, including diversion airports.
Lion Air Flight 610 - October 29, 2018
A Boeing 737 MAX operated by Lion Air crashed into the Java Sea shortly after takeoff from Jakarta, killing all 189 people on board. Investigations pointed to a newly introduced flight control system, the Maneuvering Characteristics Augmentation System (MCAS), which repeatedly pushed the aircraft's nose down. Pilot inability to counteract the system's actions, compounded by issues with maintenance and pilot training, contributed to the disaster. This crash led to the global grounding of the entire Boeing 737 MAX fleet for an extended period, prompting a thorough re-evaluation of the aircraft's design and certification process.
Ethiopian Airlines Flight 302 - March 10, 2019
Just months after the Lion Air crash, another Boeing 737 MAX, operated by Ethiopian Airlines, crashed shortly after takeoff from Addis Ababa, killing all 157 people on board. Similar to the Lion Air incident, the investigation identified the MCAS system as a primary factor. The repeated failure of the 737 MAX, occurring so close together, intensified scrutiny on Boeing, its safety culture, and the regulatory oversight by aviation authorities.
