US airlines skip latest Boeing 737 Max flight‑management software amid FAA review
Based on · First reported
Sources
- U.S. airlines have avoided installing Boeing’s latest 737 Max flight‑management software versions for years.
- The FAA’s corrective action review board determined the vertical navigation glitch did not pose a safety risk; the glitch first appeared in WestJet operations in November 2024 and the fourth major software update has shown anomalies ranging from loss of capabilities to crew distractions. A 2022 United Airlines runway‑landing error was linked to a software anomaly. The CARB decision is expected to clear the 737‑7 for delivery by year‑end and the 737‑10 for certification in the coming days.
- The FAA’s forthcoming airworthiness directive will eventually address the U13 software issue.
