Alaska Air Grounds Entire 737-9 Max Fleet Following Additional Incident Reports
SEATTLE, WA – Alaska Air Group has announced the immediate grounding of its entire Boeing 737-9 Max fleet, effective 8:00 AM Pacific Standard Time on October 10, 2023. The decision was made following the submission of three separate maintenance reports involving potential pressurization system malfunctions on aircraft of the same model within the last 48 hours.
The Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) have been notified and are coordinating with Alaska Air safety inspectors. Preliminary investigations indicate that the reports originated from flights operating out of Seattle-Tacoma International Airport and Portland International Airport.
What began as a single incident involving a rapid cabin altitude warning on flight 482 has now expanded into a broader safety check. The airline states that no injuries or emergency landings occurred in these latest cases, but the pattern of alerts has prompted a proactive fleet-wide suspension of operations.
Alaska Air officials confirmed that 65 of their 737-9 Max aircraft are affected. Passengers with flights scheduled on these planes are being automatically rebooked on alternative aircraft or offered full refunds. The airline advises all affected travelers to monitor the status of their itineraries through the official Alaska Air mobile application or website. A timeline for the resumption of operations has not been provided pending a full engineering review.
