Are 737 Max Planes Still Grounded? | Current Status Explained

The Boeing 737 MAX aircraft is no longer grounded globally and has been safely operating with extensive modifications since late 2020.

Many travelers still carry a valid question about the 737 MAX aircraft, wondering about its operational status after the significant events of a few years ago. It’s completely understandable to seek clarity on the planes you might be flying. Let’s delve into the facts of where things stand today with the 737 MAX.

The Initial Grounding: A Global Pause

The story of the 737 MAX’s grounding began with two tragic accidents involving the aircraft within a short timeframe. These events prompted an unprecedented global response from aviation authorities.

The Tragic Events

On October 29, 2018, Lion Air Flight 610, a 737 MAX 8, crashed shortly after takeoff from Jakarta, Indonesia, resulting in the loss of all 189 people on board. Just five months later, on March 10, 2019, Ethiopian Airlines Flight 302, also a 737 MAX 8, crashed six minutes after takeoff from Addis Ababa, Ethiopia, killing all 157 passengers and crew.

Investigations into both accidents pointed to a common factor: the aircraft’s Maneuvering Characteristics Augmentation System (MCAS). This automated system, designed to prevent stalls, received erroneous angle-of-attack sensor data, repeatedly pushing the aircraft’s nose down despite pilot input.

The Global Response

Following the Ethiopian Airlines crash, aviation authorities worldwide, including the Federal Aviation Administration (FAA) in the United States, issued emergency orders to ground all 737 MAX aircraft. This decision, made in March 2019, removed approximately 387 aircraft from service globally, marking one of the most significant groundings in aviation history.

Understanding the Path to Recertification

The process to unground the 737 MAX was exhaustive, involving rigorous scrutiny from regulatory bodies across the globe. It wasn’t a quick fix but a comprehensive re-evaluation of the aircraft’s systems and operational procedures.

Regulatory Oversight and Collaboration

The FAA, as the certifying authority for Boeing aircraft, led the recertification process in the United States. However, international regulators like the European Union Aviation Safety Agency (EASA), Transport Canada, and Brazil’s National Civil Aviation Agency (ANAC) conducted their own independent reviews. This collaborative yet independent approach ensured a thorough examination of all proposed changes.

The FAA’s ungrounding decision in November 2020 came after a nearly two-year review, requiring significant software updates and revised pilot training. According to the FAA, this extensive review involved thousands of hours of work by FAA safety experts, engineers, and test pilots, culminating in the issuance of an Airworthiness Directive.

Key Software and System Updates

The core of the recertification involved a complete overhaul of the MCAS software. This update ensured that MCAS would only activate once, would not repeatedly push the nose down, and would be limited in its authority. It also required the system to compare data from two angle-of-attack sensors, rather than relying on just one, and alert pilots if there was a discrepancy.

Beyond software, Boeing also implemented other system improvements and provided comprehensive documentation to airlines and pilots. The focus was on enhancing redundancy, improving pilot awareness, and ensuring pilots could easily override automated systems if needed.

The Return to Service: A Phased Approach

The ungrounding of the 737 MAX was not a single event but a phased return to service, with different countries and regions issuing their approvals at varying times.

US Ungrounding and First Flights

The FAA lifted its grounding order on November 18, 2020. This paved the way for airlines in the United States to begin preparing their 737 MAX fleets for service. American Airlines was the first US carrier to resume commercial flights with the 737 MAX on December 29, 2020, followed by other major operators in the subsequent weeks and months.

International Ungroundings

Following the FAA’s lead, other major aviation authorities progressively lifted their grounding orders. EASA, for instance, issued its directive in January 2021, and Transport Canada followed shortly after. This staggered approach allowed each regulator to complete its independent validation and ensure all specific national requirements were met before allowing the aircraft back into their airspace.

Enhanced Safety Measures: What Changed?

The return to service for the 737 MAX wasn’t simply about a software update. It involved a multi-faceted approach to safety, addressing not only the technical aspects but also pilot training and operational oversight.

Mandatory Software and System Updates

Every 737 MAX aircraft underwent the required software updates to the MCAS system and other flight control systems. These changes were verified by regulators and Boeing engineers. Beyond software, wiring bundles were inspected and modified to prevent potential short circuits, ensuring electrical integrity.

Rigorous Pilot Training Requirements

A significant change was the requirement for all 737 MAX pilots to undergo mandatory simulator training. This training specifically focused on scenarios involving MCAS activation and other flight control anomalies, ensuring pilots had hands-on experience in handling such situations. This goes beyond previous training protocols for the aircraft type.

Airlines also updated their operational manuals and procedures to incorporate the new system behaviors and pilot responses. This ensures that flight crews are fully prepared for any eventuality, with clear guidelines and checklists.
