The FAA grounded more than 170 Boeing 737 Max 9 aircraft over the weekend when it introduced an emergency airworthiness directive (AD) requiring immediate inspection of mid-exit plug doors. This followed the January 5 incident in which an Alaska Airlines aircraft depressurized soon after takeoff from Portland International Airport in Oregon. NTSB officials are investigating the incident, which involved Flight 1262 landing safely with 174 passengers and six crew members on board after the door detached from the fuselage at around 16,000 feet.

According to a fleet analysis by IBA, the grounding could disrupt operations for around 85 percent of the 216 Max 9s delivered to date, with most of these being operated by Alaska and United Airlines. The UK-based aviation consultancy said that the Max 9 BBJ large-cabin business jet also has the mid-exit plug door—while indicating that its records show just one example of this variant in service today.
