FAA delays Boeing 737 MAX 10 certification over software issue
The FAA delayed Boeing 737 MAX 10 certification due to a flight management computer software issue. Boeing and GE Aerospace are addressing the problem, but the delay's duration is uncertain. Airlines like United and Southwest have refused aircraft with the affected software. According to Boeing, a permanent fix was initially expected in 2028.
