The crash of Alaska Airlines Flight 1282 on Jan. 5 has once again thrust Boeing Co.'s 737 Max aircraft - by far its most popular aircraft and largest source of revenue - into the spotlight. The manufacturer's entire Max fleet was suspended from service in 2019 following two fatal crashes. After the 737-9 Max crash last Friday, the U.S. Federal Aviation Administration has ordered a temporary partial grounding of the aircraft, a move that has prompted global regulators and airlines to take precautions and discuss next steps.

Here's what regulators, governments and airlines are taking

Regulators and Government Agencies

North America

- The U.S. Federal Aviation Administration (FAA) ordered the temporary grounding and inspection of some 737-9 Max aircraft. According to a statement from the FAA, the move affects approximately 171 aircraft worldwide.

-The U.S. National Transportation Safety Board is also investigating the matter. Its chairwoman, Jennifer Homendy, said the investigation will include a review of the FAA's oversight of Boeing and the aircraft manufacturing process for the affected models.

Europe

- The European Union Aviation Safety Agency (EASA) told Bloomberg News that it has adopted the FAA’s emergency directive. No European airlines from EASA member states operate the affected Boeing aircraft.

- The UK Civil Aviation Authority said it has informed non-UK and foreign airlines in writing of the checks they need to carry out before flying into or over UK airspace. There are currently no 737-9 Max aircraft registered in the UK.

Asia

- The Civil Aviation Administration of China held an emergency meeting on Saturday night regarding the Alaska Airlines incident to consider how to respond to the fuselage explosion, Bloomberg News reported. No Chinese airline operates 737-9 Max aircraft.

- India's Directorate General of Civil Aviation has asked airlines to conduct one-time inspections of Boeing's 737-8 Max aircraft. Like China, no Indian airline operates the 737-9 Max aircraft.


airline actions

- Alaska Airlines Group, the airline at the center of the turmoil, initially grounded all 65 of its 737-9 Max planes hours after the crash. It later allowed 18 of the planes to resume flying after detailed maintenance inspections, but then grounded all of them.

- United Airlines, the largest operator of the affected Max aircraft, said all 79 of its aircraft were temporarily grounded. The next step is for the airline to work with the FAA to determine inspection procedures and requirements for returning the aircraft to service. The company earlier said 33 of the planes underwent necessary inspections before all aircraft were grounded.

- Copa Airlines said it has grounded 21 affected aircraft. The airline's fleet totals 29 aircraft but operates in two different configurations.

- Aeromexico follows United Airlines and Alaska Airlines in grounding all 19 of its 737-9 Max jets for inspection.

- Icelandair said its small fleet of 737-9 Max aircraft is not affected by FAA inspections. The airline has been in contact with Boeing and the FAA.

- Turkish Airlines said the country's civil aviation authority asked it to inspect its small fleet of five 737-9 Max aircraft. The airline has grounded the planes until a technical review is completed.

- Flydubai told Bloomberg News that its three 737-9 Max aircraft are not affected by the FAA directive.
