The FAA concluded a software fault in certain Boeing 737 MAX flight computers is not a safety concern because pilots retain full control and cockpit indications remain clear. The bug can affect automated flight guidance when switching approach modes during landing. Boeing will issue a bulletin to operators, is working on a software update and formal procedures with airlines, and the MAX 10's certification remains paused pending further assurance.

The Federal Aviation Administration (FAA) said on Friday that a software fault discovered in a cockpit update for Boeing's 737 MAX 10 does not constitute a safety concern after a panel review, though the variant's certification remains paused while the issue is addressed.
What Happened
Investigators found a glitch in flight computers that can cause an automated navigation or flight-guidance feature to become unavailable when an aircraft switches approach modes during landing. The condition was identified during checks related to certification of the MAX 10.
"Following a thorough review, a panel of FAA safety experts on Friday determined a software issue in certain Boeing 737 MAX flight computers is not a safety concern," the FAA said in a statement.
The FAA review board said the assessment rests on two points: pilots maintain full control of the airplane, and the indications presented to flight crews are clear and unambiguous. The agency added it will consider further action if new information emerges.
Boeing Response
Boeing notified operators that pilots may lose access to automated flight guidance in a specific landing scenario and told airlines it will issue a bulletin explaining how to recognize and respond to the condition. In a statement to AFP, Boeing said, "We will continue to follow the lead of the FAA as our engineers work on the next software update." The company is also coordinating with carriers to formalize a procedure allowing crews to restore automated guidance if the anomaly occurs in service.
Certification Status
Neither the FAA nor Boeing confirmed whether the certification hold on the 737 MAX 10 will be lifted following the panel's review. FAA Administrator Bryan Bedford told reporters the MAX models certified so far are safe but that "we will be delaying the 10 until... we're satisfied we don't have an issue here."
Outlook
The FAA's finding clears the way for continued operational use of already-certified MAX variants but leaves the MAX 10's entry into service pending completion of Boeing's software update, airline procedures, and any additional regulatory review that may follow.
