Boeing Deliveries Hit 60 in May as Orders Face Headwinds

Boeing Operational Recovery Accelerates

Boeing delivered 60 commercial aircraft in May 2026, marking a 33% increase from the 45 jets delivered during the same period in 2025. This performance highlights a steady operational recovery for the manufacturer, which has been working to stabilize production lines following a series of quality-related disruptions. According to the Boeing May 2026 Orders and Deliveries Report, the May total included 51 737 MAX aircraft, the highest monthly output for the narrowbody program since production restarted in December 2024.

Despite the delivery uptick, the company's order book faced pressure. While Boeing recorded 27 gross orders throughout the month, net new orders totaled only 11 after accounting for 16 cancellations for the 737 MAX. The manufacturer's total commercial aircraft unfilled order backlog stands at 6,178 jets as of the end of May 2026.

Production Stability and Regulatory Oversight

The Federal Aviation Administration (FAA) previously limited Boeing to producing 38 MAX jets per month following a January 2024 door plug blowout. This cap was officially lifted in October 2025, providing the company with the regulatory clearance to gradually increase output. Boeing currently aims to reach a production rate of 47 aircraft per month by mid-summer 2026. CEO Kelly Ortberg emphasized in a recent management update that the company is prioritizing system stability over speed, noting that the ramp-up will only proceed when the production environment is fully validated.

This recovery path has not been without challenges. Boeing is currently navigating the impact of a minor wiring defect discovered in March 2026, while also addressing ongoing certification bottlenecks for the MAX 7 and MAX 10 variants. These certification delays, partly linked to a required permanent design fix for the CFM International Leading Edge Aviation Propulsion 1B engine anti-ice system, continue to disrupt fleet planning for major carriers like Southwest Airlines.

Technical Analysis: The Certification Gap

The delay in certifying the MAX 7 and MAX 10 variants remains a significant structural force influencing Boeing's current market position. The FAA Airworthiness Directives mandate a permanent engineering solution for the engine nacelle inlet overheating risk, a process that necessitates rigorous flight testing. Historically, this type of regulatory scrutiny mirrors the 2021 787 Dreamliner delivery halt, where quality control flaws led to a massive backlog. While the current delivery volume of 60 jets per month indicates progress, the inability to deliver the larger or longer-range variants limits Boeing's ability to compete directly with the Airbus A321neo in the high-capacity narrowbody segment.

What Comes Next: Production Milestones

Boeing is tracking several key milestones as it moves into the second half of 2026. The company is confirmed to open its fourth 737 MAX final assembly line in Everett on July 6, 2026. This expansion is expected to support the target production rate of 47 jets per month by mid-summer. Meanwhile, the FAA certification for the 737 MAX 10 is expected to span into late 2026 or 2027, subject to the successful validation of the engine anti-ice system redesign.

Why This Matters for Stakeholders

For investors and airline partners, the current delivery cadence signals a return to revenue generation, yet the soft net order intake highlights lingering market sensitivity to certification timelines. For stakeholders like Spirit AeroSystems, the pressure to maintain quality while scaling production remains the primary operational hurdle. As Boeing balances these competing demands, the industry remains focused on whether the firm can sustain its current output trajectory without triggering further regulatory interventions.
