The Boeing 737 MAX was grounded worldwide in March 2019 following two fatal crashes, and while it has as been recertified and returned to service, ongoing scrutiny and production issues continue to affect the aircraft and BoeingS reputation as of January 19, 2026.
The Boeing 737 MAX Grounding
Table of Contents
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. Both 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 (AOA) sensor. In both crashes, a faulty AOA sensor triggered MCAS, and pilots struggled to regain control of the aircraft. Investigations revealed that Boeing failed to adequately inform pilots about MCAS and its potential dangers.
Example: The final report of the Joint Investigators Team (JIT) for the Ethiopian Airlines Flight 302 crash, released in July 2019, detailed the sequence of events and the role of MCAS in the accident. Ethiopian Airlines Flight 302 Final Report
Recertification and Return to Service
The Federal Aviation Governance (FAA) initiated a review of the 737 MAX’s design and safety systems following the crashes.The FAA required boeing to make notable software updates to MCAS, including using input from two AOA sensors and limiting the system’s authority. Pilots were also required to undergo additional training.
On November 18, 2020, the FAA issued an Airworthiness Directive lifting the grounding order, but airlines were not promptly allowed to resume flights. The FAA mandated that all 737 MAX aircraft undergo maintenance and software updates before returning to service. Different countries had varying timelines for recertification,with some,like china,delaying the process substantially.
Detail: The FAA’s recertification process involved over 60,000 hours of testing and analysis, including simulator evaluations and flight tests. FAA Lifts 737 MAX Grounding Order
Recent Developments (as of January 19, 2026)
As of january 19, 2026, the Boeing 737 MAX is back in service with most major airlines globally, but Boeing continues to face scrutiny regarding production quality and safety concerns. in January 2024, the FAA temporarily grounded 171 737 MAX planes worldwide after a door plug blew out mid-flight on Alaska Airlines Flight 1282. This incident prompted another FAA audit of Boeing’s manufacturing processes.
The FAA has imposed stricter oversight of Boeing,including limiting the company’s production rate and requiring autonomous inspections of each 737 MAX aircraft. Boeing has also faced investigations by the Department of Justice regarding potential criminal charges related to the 737 MAX crashes and the subsequent cover-up. In December 2025, boeing announced a restructuring of its engineering and quality control departments in response to the ongoing issues.
Example: The FAA issued a Notice of Proposed Safety Certificate (NPSC) to Boeing in February 2024, outlining deficiencies in the company’s safety management system. FAA Finds Safety Deficiencies in boeing Manufacturing Process. as of January 19, 2026, Boeing is working to address these deficiencies and regain full FAA certification.
