The Boeing 737 MAX
was first grounded by Ethiopian Airlines on 10 March 2019, following the MCAS-induced
crashes of Lion Air Flight 610
and Ethiopian Airlines Flight 302
On 11 March 2019, the Civil Aviation Administration of China
was the first major regulator to suspend all operations of the 737 MAX 8. The European Union Aviation Safety Agency followed suit
and prohibited all 737 MAX flight in EU airspace on 12 March 2019. On 13 March 2019, the US Federal Aviation Administration grounded the 737 MAX aircraft
(overriding an affirmation of continued airworthiness
issued two days prior).
On 18 November 2020, the FAA cleared the MAX to return to service once necessary repairs have been made.
On 05 January 2024, Alaska Airlines Flight 1282
served by a Boeing 737 MAX 9 suffered an uncontrolled decompression of the aircraft after a rear mid-cabin exit door blew out during flight. The aircraft was 2 months old. Alaska Airlines was aware of the issue, as the incident aircraft had already been removed from flying ETOPS flights due to pressurization issues
in prior flights on 04 January 2024.
In a statement following the incident, Boeing claims safety is their first priority
, yet in December 2023 Boeing had asked the FAA for exemptions to the 737 MAX 7's certification process
to overlook a known safety issue which could cause the nacelle to detatch if the engine anti-ice was left on by pilots on for 5 minutes in non-icing conditions mid-flight, which could result in loss of control of the airplane.
