FAA Clears Boeing 737 MAX Software Glitch, Removing Key Hurdle for MAX 10
The U.S. Federal Aviation Administration (FAA) has determined that a software glitch affecting some Boeing 737 MAX flight computers does not pose a safety concern, removing a major regulatory obstacle for Boeing as it seeks certification of the 737 MAX 10.
The FAA’s Corrective Action Review Board concluded that pilots retain full control of the aircraft and receive clear indications if the software issue occurs. The decision is particularly important for Boeing because the MAX 10, the largest version of the 737 MAX family, had faced a certification delay after the software problem emerged.
For investors, the development reduces one immediate regulatory uncertainty surrounding Boeing. It also brings the company closer to certification of the MAX 10, which has a substantial order backlog from major airlines.
What is the Boeing 737 MAX software problem?
The issue involves software used by some 737 MAX flight computers and affects automated vertical navigation during a particular landing scenario.
The problem can arise after a missed approach, commonly called a go-around, when the flight crew subsequently modifies the aircraft's flight path. Under the affected software configuration, pilots could lose access to automated flight guidance in that specific situation.
The FAA's latest review found that this does not compromise the aircraft's safety because pilots remain in control and cockpit indications are sufficiently clear. Boeing is nevertheless working on a software update, while interim procedures are being provided to pilots.
The distinction is important: the FAA has determined that the issue does not constitute a safety threat, but Boeing is still addressing the underlying software problem.
WestJet first identified the issue in 2024
The software anomaly was not discovered for the first time in 2026.
WestJet pilots identified the problem during an entry-into-service validation flight in 2024 and reported it to Boeing, according to a memo reviewed by Reuters. The airline subsequently provided supporting information to the manufacturer.
The issue became particularly significant this year because of its implications for certification of the 737 MAX 10.
The FAA had initially delayed MAX 10 certification while it assessed whether the problem could create a safety risk. The agency's latest conclusion removes that central concern.
Why the MAX 10 certification matters to Boeing
The 737 MAX 10 is the largest aircraft in Boeing's 737 MAX family and is an important part of the company's future narrowbody product lineup.
Boeing has accumulated roughly 1,500 MAX 10 orders, making certification strategically important for both the manufacturer and its airline customers. Reuters reported that certification could now take place as early as later in October.
Airlines including Southwest, United Airlines and Alaska Airlines have been waiting for the aircraft, making the certification timeline relevant to their fleet-planning decisions.
The MAX 10 is designed for high-capacity short- and medium-haul routes and competes with aircraft in the upper end of the narrowbody market.
For Boeing, getting the aircraft certified would expand its ability to deliver against an existing order backlog and provide airlines with another option for replacing older aircraft.
Boeing still faces a broader production and safety challenge
The FAA's decision is positive for Boeing's immediate certification prospects, but it should not be viewed in isolation.
The company continues to operate under increased regulatory oversight following years of safety and production-quality problems.
The FAA said in July 2026 that Boeing could resume issuing airworthiness certificates for new 737 MAX and 787 aircraft after months of safety and production review. However, the agency said inspectors would continue monitoring Boeing's manufacturing processes, safety management system and production quality.
The MAX program also remains closely associated with the two fatal crashes in 2018 and 2019 that led to the worldwide grounding of the aircraft.
The FAA's earlier review of the MAX resulted in extensive changes involving flight-control software, cockpit alerts, pilot procedures and other systems.
That history explains why even a relatively contained software issue can receive significant regulatory attention.
What the FAA decision means for Boeing investors
The immediate financial significance is linked to certification and deliveries.
Boeing has a large commercial-aircraft backlog, and additional certified MAX variants can provide the company with greater flexibility in converting orders into deliveries.
Aircraft deliveries are particularly important to Boeing's cash flow because customers make substantial payments around delivery milestones.
The MAX 10 therefore matters beyond the aircraft's technical specifications. Certification can help Boeing broaden its commercial product portfolio and work through its existing order book.
However, investors still need to distinguish between regulatory clearance of a software issue and an improvement in Boeing's overall financial position.
The FAA decision does not by itself resolve production challenges, supply-chain constraints, delivery execution or the company's broader financial recovery.
Why this matters for airlines
Airlines that have ordered the MAX 10 gain greater visibility into fleet planning if certification proceeds as expected.
United, Southwest and Alaska are among the carriers connected to the aircraft's order pipeline. The certification timeline matters because airlines need to plan aircraft retirements, route capacity and pilot training well in advance.
A prolonged certification delay could have forced airlines to continue operating existing aircraft longer or adjust fleet plans.
The latest FAA finding reduces that particular uncertainty, although the remaining certification process still has to be completed.
Could the issue affect Boeing's stock?
The FAA decision removes an important negative uncertainty that had recently surrounded Boeing's shares.
Boeing's stock had fallen sharply after the FAA delayed MAX 10 certification following disclosure of the software issue. Reuters reported that the shares dropped 6.9% on September 28 when the certification delay was announced.
The latest ruling could therefore improve investor sentiment because the specific software issue has now been judged not to present a safety concern.
However, stock-market reactions can depend on much more than one certification development.
Investors will continue to watch Boeing's aircraft deliveries, free cash flow, production rates, supplier performance and progress toward stabilising its manufacturing operations.
What investors should watch next
The most immediate catalyst is the formal certification process for the 737 MAX 10.
Investors should also monitor Boeing's implementation of the software fix and the FAA's planned communication to operators. The agency has said it plans to issue a Special Airworthiness Information Bulletin to keep domestic and international operators informed.
Beyond the MAX 10, several broader indicators remain important:
- Boeing's monthly commercial-aircraft deliveries
- 737 production and delivery rates
- Free cash flow and debt reduction
- Supplier and manufacturing quality
- Progress on the company's safety-management improvements
- New aircraft orders and cancellations
- Further FAA regulatory actions
For Boeing, consistent execution may ultimately matter more than any single certification milestone.
Boeing gets regulatory relief, but the recovery continues
The FAA's conclusion that the 737 MAX software glitch poses no safety issue removes a significant hurdle for Boeing's MAX 10 certification effort.
The finding also provides some clarity for airlines waiting for the aircraft and for investors tracking Boeing's commercial-aircraft recovery.
Still, the decision addresses one specific software problem rather than Boeing's broader operational challenges. The next important test will be whether the company can turn regulatory progress into reliable production, deliveries and stronger cash generation.
For investors, the key event to watch now is the formal certification and subsequent delivery ramp-up of the 737 MAX 10, alongside Boeing's wider progress on production quality and financial performance.
