Why U.S. airlines balked at adopting Boeing’s latest 737 Max software versions

Federal regulators have cleared a Boeing 737 Max flight management software glitch after a safety review, determining the issue does not pose a flight safety risk. U.S. carriers have avoided installing the latest flight management software versions for years due to concerns over cockpit glitches, opting instead to keep an earlier version that was released nearly a decade ago. The software issue recently surfaced as a hurdle during the certification process for the 737 Max 10 and created uncertainty surrounding the initial delivery of the Max 7.

  1. FAA Clears Boeing 737 Max Software Glitch

    Federal regulators have cleared a Boeing 737 Max flight management software glitch after a safety review, determining the issue does not pose a flight safety risk. U.S. carriers have avoided installing the latest flight management software versions for years due to concerns over cockpit glitches, opting instead to keep an earlier version that was released nearly a decade ago. The software issue recently surfaced as a hurdle during the certification process for the 737 Max 10 and created uncertainty surrounding the initial delivery of the Max 7.

    Why it matters

    Major U.S. carriers have actively bypassed installing recent software editions for the aircraft family, preferring decade-old code because cockpit bugs can distract flight crews during critical phases of flight. The recent scrutiny arose while aviation regulators evaluated missed-approach conditions that could impact vertical navigation capabilities. These recurring software challenges affect newer variants requiring the updated code base, including the upcoming Max 10 certification and Max 7 delivery timelines.

    What is confirmed

    • The Federal Aviation Administration stated that a Boeing 737 Max software glitch is not a flight-safety issue.
    • WestJet first alerted Boeing about the 737 Max software glitch that was subsequently cleared by the FAA.
    • U.S. airlines have avoided installing the latest flight management software versions for Boeing's 737 Max aircraft for years.

    Still unconfirmed

    • U.S. carriers rely on an earlier flight management software version rolled out nearly a decade ago due to concerns over cockpit glitches distracting crews during critical landing phases.

    What to watch next

    • Certification progress and timeline updates for the Boeing 737 Max 10
    • First delivery schedule announcements for the Boeing 737 Max 7
