Grounding Info
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, 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. On 13 March, the US Federal Aviation Administration grounded the 737 MAX aircraft (overriding an affirmation of continued airworthiness issued two days prior).
The Boeing 737 MAX remains grounded, pending recertification of the aircraft, not likely to be before mid-2020.
