The FAA has delayed certification of Boeing's 737 MAX 10 after identifying a software issue that could prevent pilots from accessing automated flight guidance during a specific landing scenario. Pomerantz LLP has opened an investigation into whether Boeing and certain officers or directors engaged in securities fraud or other unlawful business practices after the disclosure sent Boeing shares down $13.68, or 6.91%, to $184.39 on Sept. 28, 2026. The issue followed a software update and could affect automated navigation information during a go-around, increasing pilot workload while leaving pilots in control. FAA Administrator Bryan Bedford said the agency had not determined whether the problem was a safety-of-flight issue. The FAA plans to convene a Corrective Action Review Board, while Boeing has said it will follow the regulator's lead. The MAX 10 is Boeing's last MAX-family variant awaiting FAA certification and is important to its competition with Airbus in the single-aisle market.
