The Boeing 737 MAX series is once again in the spotlight after the door plug on a 737 MAX 9 of Alaska Airlines suddenly blew out during midflight. While this incident is only isolated to the Boeing 737 MAX 9 with the same door configuration as that of Alaska Airlines, the general public is now questioning if the plane is still safe, especially after the FAA has grounded it again. However, I want to point out a few things.
First, the recent groundings of the 737 MAX are limited only to the MAX 9 series that shares the same door configuration as that of Alaska Airlines. As such, not all airlines operating the 737 MAX 9 are affected. Here is a list of those airlines.
Second, yes, the Boeing 737 MAX is already safe to fly, given all the extensive improvements in its software, avionics, and even training. In fact, in 2023, the 737 MAX received 883 orders while 387 planes were delivered. Southwest Airlines and United Airlines are the top operators of the 737 MAX and also have the most number of pending orders waiting to be delivered.
So, what has the 737 MAX undergone in order for it to be deemed safe?
Software Upgrades and Training Enhancements
Boeing’s response to these challenges was multifaceted. Key among the changes was a significant overhaul of the MCAS software. The updated system now receives input from both angle-of-attack sensors, reducing the risk of erroneous activation and incorporating additional safeguards. This crucial modification aims to prevent the recurrence of similar issues.
Pilot training has also seen a substantial upgrade. Pilots are now required to undergo specific training focused on the updated MCAS system and related procedures. This comprehensive training, which includes classroom instruction and simulator sessions, ensures pilots are well-versed in the changes and prepared to handle potential issues.
Regulatory Approval and Independent Reviews
The path to the 737 MAX’s return to service was paved with rigorous regulatory approval processes. Aviation authorities, including the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA), meticulously reviewed the modifications. Their assessments were crucial in ensuring the aircraft met the highest safety standards.
In addition to regulatory scrutiny, independent third-party experts and aviation organizations conducted their assessments. These reviews were instrumental in verifying the effectiveness of the safety improvements and confirming the aircraft’s readiness for operation.
Enhanced Safety Features and System Redundancy
Boeing’s commitment to safety is evident in the additional features implemented in the 737 MAX series. For instance, a disagree light has been added to the flight deck, alerting pilots to discrepancies between angle-of-attack sensors. This feature enhances pilot awareness and contributes to early problem detection.
System redundancy has been another focus area. The 737 MAX now utilizes data from both angle-of-attack sensors for cross-checking, thereby preventing erroneous sensor readings from impacting flight controls. This redundancy is a vital step in enhancing overall aircraft safety.
Collaboration and Continuous Improvement
Boeing’s approach to updating the 737 MAX involved active collaboration with airlines and pilot unions. This engagement ensured that concerns were addressed, insights from experienced pilots were incorporated, and a comprehensive approach to safety enhancements was achieved.
Independent review panels, consisting of aviation experts and industry stakeholders, were established to evaluate the aircraft’s design, systems, and certification processes. Their evaluations and recommendations provided an additional layer of scrutiny and guidance for improvements.
The Future of the Boeing 737 MAX
As the 737 MAX continues to fly, ongoing monitoring and oversight by global aviation regulators remain in place. Regular inspections, audits, and data analysis are conducted to promptly identify and address any emerging issues.
The incidents involving the 737 MAX have led to a broader examination of safety culture within Boeing. The lessons learned from these events have sparked a renewed focus on safety, transparency, and open communication. This shift is essential in preventing similar issues in the future and maintaining the trust of passengers and the customers.
The Boeing 737 MAX’s journey has been one of resilience, learning, and improvement. While no aircraft can be deemed completely safe, and accidents can still occur, aircraft manufacturers continually strives to enhance flying safety. The extensive modifications, rigorous training, regulatory approvals, and ongoing oversight have significantly made the 737 MAX more safe. So if you will soon be on board a Boeing 737 MAX, then there’s nothing to worry about.
