The Federal Aviation Administration (FAA) has determined that a flight management system software anomaly on certain Boeing 737 MAX aircraft does not constitute a safety-of-flight risk, clearing a critical regulatory hurdle for the certification of the Boeing 737 MAX 10. The decision, reached on October 2, 2026, by the agency’s Corrective Action Review Board (CARB) in Seattle, Washington, resolves a review that had temporarily paused the MAX 10 certification process earlier in the week.

According to Reuters, the ruling also alleviates operational compliance concerns for airlines flying the recently certified Boeing 737 MAX 7, which utilizes the same software version. The FAA paused the certification process for the MAX 10 during the week of September 28, 2026, to allow the CARB to complete a thorough analysis of the software behavior.

Flight management system anomaly details

The software glitch affects the flight management system (FMS) software versions U14 and U14.1, which are supplied to Boeing by GE Aerospace. According to technical details reported by Bloomberg via the Japan Times, the anomaly can cause the vertical navigation (VNAV) mode to disengage during a go-around or missed approach if the flight crew modifies the preprogrammed route. This disengagement forces the autopilot into a simpler level of automation for pitch control, subsequently increasing crew workload during a critical phase of flight.

Pilots at WestJet Airlines Ltd. first identified the software anomaly in 2024 during an entry-into-service validation flight and subsequently reported the behavior to Boeing. Despite the technical fault, the issue has not manifested during standard commercial flights. In an internal staff memo reviewed by Reuters, WestJet noted that the airline “has received no reports of this condition occurring during normal line operations.”

The FAA ultimately concluded that the software behavior does not cross the threshold into a safety-of-flight issue. In a statement provided to Aviation Week, the regulator explained that the CARB reached its determination because flight crews maintain full control of the aircraft, and the system indications presented to the pilots remain “clear and unambiguous.”

Operator impact and fleet status

The FAA certified the Boeing 737 MAX 7 in August 2026 with the affected FMS software installed. Following that certification, Boeing formally notified operators of the potential VNAV disengagement issue. The CARB’s October 2, 2026, determination ensures that the MAX 7 can continue operations without immediate regulatory intervention or grounding orders.

However, the presence of the software has influenced fleet planning for major US carriers. According to reporting by Bloomberg News via TradingView, United Airlines, Southwest Airlines, and Alaska Airlines have all confirmed that their active fleets do not utilize the faulty software versions. Furthermore, United Airlines has stated it is not accepting new aircraft equipped with the affected FMS software.

To manage the issue across the broader industry, the FAA is expected to issue a Special Airworthiness Information Bulletin (SAIB) in October 2026. The bulletin will formally notify US carriers and foreign aviation regulators regarding the technical specifics of the anomaly and the recommended operational procedures.

The Boeing 737 MAX 10 certification path

The Boeing 737 MAX 10 is the largest variant of the manufacturer’s best-selling narrowbody commercial aircraft family. The programme has faced years of certification delays, making the recent regulatory pause a point of significant concern for the aerospace manufacturer. The MAX 10 is critical to Boeing’s long-term production plans and future cash generation.

Boeing currently holds more than 1,500 orders for the MAX 10 variant. With the CARB determination removing the immediate regulatory roadblock, the FAA can resume the certification process. Concurrently, Boeing is developing a permanent software update to address the FMS anomaly, though a specific timeline for the deployment of that patch has not been officially released.

We note that while the FAA’s Corrective Action Review Board has removed the immediate regulatory roadblock for the Boeing 737 MAX 10, a commercial disconnect remains. The regulatory determination that the software is safe for flight does not automatically translate to operator acceptance, as evidenced by United Airlines declining deliveries of aircraft equipped with the current software version. Until Boeing finalizes and deploys its permanent software patch, the manufacturer may face a backlog of completed airframes that airlines are unwilling to induct into their active fleets, potentially delaying the financial benefits of the MAX 10’s eventual certification.

FLYONE Armenia has finalized a firm order for two Airbus A321neo aircraft, marking the carrier’s first direct purchase from the European manufacturer. The agreement, announced on September 30, 2026, signals a strategic transition for the Yerevan-based airline from relying on leased capacity to acquiring new-generation airframes directly from the factory.

The transaction stems from a Memorandum of Understanding (MoU) signed on May 5, 2026, during French President Emmanuel Macron’s diplomatic visit to Armenia. According to the Airbus press release, the new aircraft will feature a high-density 239-seat all-economy configuration and will be powered by CFM International LEAP engines to support the airline’s network expansion.

Fleet modernization and strategic shift

The transition to direct manufacturer orders represents a significant capital commitment for the five-year-old airline. FLYONE Armenia Chief Executive Officer Aram Khachatryan described the direct order as a symbolic milestone for the airline’s development.

“Having two new A321neo aircraft built by Airbus specifically for our airline reflects our continued commitment to fleet modernisation and long-term growth,” Khachatryan said. “We are proud to strengthen our partnership with Airbus and are confident that this investment will support not only FLYONE Armenia’s future development, but also the continued growth of Armenia’s civil aviation sector and its international cooperation.”

Benoît de Saint-Exupéry, Executive Vice President of Sales for the Commercial Aircraft business at Airbus, noted that the order underscores the airline’s focus on operational efficiency as it expands its Airbus A320 Family fleet. He added that the manufacturer anticipates a deep collaboration to support the carrier’s strategic growth plans.

Market context and FlyOne Group expansion

Established in 2021, FLYONE Armenia operates as a low-cost carrier (LCC) out of Zvartnots International Airport (EVN) in Yerevan. The airport represents a rapidly growing market, recently surpassing 5.6 million annual passengers. In this environment, FLYONE Armenia competes directly with ultra-low-cost carriers (ULCC) such as Wizz Air and legacy operators including Aeroflot.

The airline is part of the broader FlyOne Group, which manages carriers in Moldova and Romania. On August 24, 2026, sister airline FlyOne Asia took delivery of its first Airbus A321-200NX, marking the group’s initial induction of the re-engined narrowbody family.

While Airbus states that FLYONE Armenia currently operates a fleet of 11 Airbus A320 Family aircraft, aviation intelligence providers note a complex fleet structure. The airline has historically relied on Aircraft, Crew, Maintenance, and Insurance (ACMI) wet-lease contracts, sourcing capacity from external operators like Avion Express and from within the FlyOne Group. Records from the Armenian Civil Aviation Committee show five aircraft on the national register, with the remaining active airframes operating under foreign registries.

We view FLYONE Armenia’s transition from ACMI and second-hand leases to direct manufacturer orders as a standard maturation milestone for a growing low-cost carrier. Securing direct delivery slots for the highly constrained Airbus A321neo indicates long-term capital commitment and a shift toward controlling unit costs through new-engine technology, rather than relying entirely on the flexibility of the wet-lease market.

Airbus has successfully completed the maiden flight of its A350F freighter, initiating a rigorous certification campaign for an aircraft designed to challenge historical market dominance in the heavy air cargo sector. The first test aircraft, designated MSN 700, departed Toulouse-Blagnac Airport (TLS) on September 29, 2026, marking a critical milestone for the European manufacturer.

In a press release issued following the flight, Airbus confirmed the aircraft completed a comprehensive initial evaluation of its systems and flight controls over southern France. The maiden flight initiates a 9-to-10-month flight test program aimed at securing regulatory approval for the new widebody freighter.

Initiating the flight test campaign

The A350F took off from runway 14R at Toulouse-Blagnac at 10:30 a.m. local time. According to reporting by Aviation Week, the departure proceeded on schedule despite gusting wind conditions at the airport. The aircraft reached a maximum altitude of 25,000 feet during the test.

Airbus reported the flight duration as 4 hours and 10 minutes, though flight tracking data published by Flightradar24 recorded the total airborne time at 4 hours and 14 minutes. Prior to the physical flight, Airbus flight test crews conducted a virtual first flight in a development simulator to validate the aircraft flight control laws and clear its new systems for airborne operation.

The crew for the maiden flight included Experimental Test Pilots Bernardo Saez-Benito Hernandez and Sylvain Guiraud, operating alongside test-flight engineers Ludovic Girard, Laurent Bussiere, and Jaime Angoloti Benavides.

“This maiden flight is a major milestone for the A350F and for our customers worldwide. As the latest development of our highly successful A350 platform, the A350F is a true game-changer for the air cargo market, combining unmatched operational flexibility, fuel efficiency, and range.”

The statement was provided by Lars Wagner, CEO of Commercial Aircraft at Airbus, who also commended the dedication of the engineering and manufacturing teams involved in the program.

Engineering a new heavy freighter

Airbus officially launched the A350F program in 2021 to meet evolving global air freight demands and replace aging legacy freighters. The aircraft is a dedicated freighter derivative of the A350 passenger family, featuring a unique fuselage configuration. It combines the forward fuselage length of the Airbus A350-900 with the rear fuselage and wing configuration of the larger Airbus A350-1000.

Constructed from over 70 percent advanced materials, the A350F is designed to offer a maximum payload capability of 111 tonnes and a maximum range of 8,700 kilometres. Airbus states the aircraft provides a 46-tonne weight reduction in maximum take-off weight (MTOW) compared to competitor aircraft with similar payload and range capabilities. This weight reduction, combined with the Rolls-Royce Trent XWB-97 engines, is projected to deliver a 40 percent reduction in fuel consumption and carbon emissions.

A central feature of the new design is the industry’s largest main deck Cargo aircraft door, measuring 4.3 metres wide. Airbus completed the manufacturing and assembly of the first main deck cargo door at its composite facility in Illescas, Spain, on April 23, 2026.

Challenging the heavy cargo market

The A350F enters a market historically dominated by Boeing, positioning itself as the first new freighter to fully meet the latest International Civil Aviation Organization (ICAO) carbon dioxide emission standards. As of the end of August 2026, the A350F program had recorded 115 firm orders.

While Airbus stated these orders come from 10 customers worldwide, an order book breakdown published by Flightradar24 lists 15 distinct entities accounting for the commitments. Atlas Air currently stands as the program’s largest customer with 20 aircraft on order. Air China Cargo, AviLease, Etihad Airways, and Starlux Airlines follow with orders for 10 aircraft each.

Path to certification

The maiden flight marks the beginning of an intensive certification campaign that Airbus expects to span 400 flight hours. The manufacturer is targeting Type Certification from the European Union Aviation Safety Agency (EASA) between late 2026 and mid-2027.

A second prototype, designated MSN 701, has already completed final assembly and is currently undergoing ground tests. Airbus confirmed the second aircraft is scheduled to enter the paint shop in the coming weeks. Once airborne, MSN 701 will focus on system-related testing, including air conditioning, water and waste systems, smoke detection, and extreme weather campaigns.

AirPro News analysis

The successful maiden flight of the A350F represents a pivotal moment in the widebody freighter market. By bringing the A350F to the skies, Airbus is actively capitalizing on the upcoming ICAO emission standards that will force the retirement of older, less efficient cargo platforms. The strong initial order book, particularly the commitment from traditional Boeing operator Atlas Air, indicates that the freight sector is highly receptive to a composite-heavy, new-generation alternative.

The aggressive 9-to-10-month certification timeline reflects Airbus’s confidence in the maturity of the baseline A350 platform. However, integrating the massive main deck cargo door and specialized freight systems will remain the primary technical hurdle during the upcoming 400-hour test campaign. If Airbus can maintain this schedule, the A350F is positioned to fundamentally alter the competitive dynamics of the heavy air cargo sector.
