"We continue to work diligently on safely returning the 737 MAX to service. We defer to the FAA and global regulators on the process," a Boeing spokesperson told the media.
The MAX has been grounded globally since March 13, 2019, following an Ethiopian Airlines crash that killed 157 people. That catastrophe came just a few months after a Lion Air MAX crash that killed 189 people.

The troubling similarities between the two accidents, both of which occurred shortly after takeoff, along with the pilots' inability to regain control of the plane, led global aviation authorities to ground the model indefinitely.
For months, the US aviation giant has been struggling to get its medium-haul aircraft -- whose sales were its main source of revenue before the grounding -- back into service.
The model's anti-stall flight system, the MCAS, was partially to blame for both crashes. But other technical malfunctions, including one involving electrical wiring, were subsequently detected during the aircraft's modification process, slowing down its recertification.
For weeks, Boeing has been awaiting the green light from authorities to conduct test flights to prove the modifications provide maximum safety.
