The Boeing 737 MAX, grounded worldwide in March 2019 following two fatal crashes, has undergone extensive software updates and safety reviews, leading to its recertification by aviation authorities. As of January 27, 2026, the 737 MAX is operating commercially in most major markets, though ongoing scrutiny and compensation claims related to the crashes continue.
The initial Grounding (2019-2020)

The Boeing 737 MAX was grounded globally on March 13, 2019, after two crashes – Lion Air Flight 610 on October 29, 2018, and ethiopian Airlines Flight 302 on March 10, 2019 – killed a total of 346 people. The crashes were linked to a faulty Maneuvering Characteristics Augmentation System (MCAS).
MCAS was designed to automatically push the nose of the aircraft down if it detected a stall, but it relied on input from a single angle-of-attack sensor. In both crashes, a faulty sensor triggered MCAS, and pilots struggled to regain control.
Example: The final report of the Ethiopian Airlines Flight 302 crash investigation, released by the Ethiopian Aircraft Accident Investigation Bureau, detailed the role of MCAS and the pilots’ inability to counteract it. Ethiopian Aircraft Accident Investigation Bureau Final Report
Key Entities Involved
- Boeing: the aircraft manufacturer responsible for designing and producing the 737 MAX.
- Federal Aviation Management (FAA): The U.S. regulatory body responsible for certifying aircraft and overseeing aviation safety. FAA Website
- National Transportation Safety Board (NTSB): The U.S. agency investigating civil aviation accidents. NTSB Website
- Lion Air & Ethiopian Airlines: The airlines operating the aircraft involved in the fatal crashes.
Recertification and Return to Service (2020-2023)
Boeing spent nearly two years developing software updates to MCAS, addressing the issues identified in the crash investigations. These updates included making MCAS rely on two angle-of-attack sensors, limiting its authority, and providing pilots with more information about its operation.
The FAA conducted a comprehensive review of the 737 MAX and the proposed software updates. This review included simulator testing, engineering analysis, and pilot training evaluations. The FAA initially faced criticism for its close relationship with Boeing and its oversight of the certification process.
Detail: The FAA’s review led to the implementation of several safety recommendations, including enhanced pilot training requirements and improved maintenance procedures. The agency also issued an Airworthiness Directive requiring the software updates before the 737 MAX could return to service.
Example: The FAA issued the Airworthiness Directive 2020-24-02 on November 18,2020,outlining the required software updates and pilot training. FAA Airworthiness directive 2020-24-02
Current Status (as of January 27, 2026)
the 737 MAX has been recertified by the FAA and other international aviation authorities, including the European Union Aviation Safety Agency (EASA). Commercial service resumed in late 2020 and early 2021,with airlines gradually phasing the aircraft back into their fleets.
As of January 27, 2026, the 737 MAX is operating regularly on domestic and international routes. Boeing continues to deliver new 737 MAX aircraft to airlines worldwide. Though,the company faces ongoing legal challenges related to compensation claims from the families of the victims of the crashes.
detail: Boeing has established a $2.5 billion fund to compensate the families of the victims and has reached settlements in many cases. However, some lawsuits remain pending. The company is also working to restore its reputation and rebuild trust with passengers and the aviation community.
Example: In February 2023, boeing announced a $100 million investment in a new engineering centre focused on safety and quality control.
