An Air Canada Boeing 737 Max plane landed on Friday due to an engine problem.
There were three crew members on board, but for passengers. No injuries were reported.
The plane was flying from Arizona to Montreal when pilots received an engine alert and decided to change course so they could settle in Tucson, Arizona, the BBC reported.
The warning was for “low hydraulic pressure of the left engine” and for a fuel imbalance problem, according to Aviation.24.be, a Belgian aviation news website.
In 2019, U.S. aviation regulators grounded all 737 Max aircraft after two fatal crashes just five months apart. The accidents – one in Indonesia and the other in Ethiopia – took 346 in total.
In mid-November, the FAA gave the agreement for the planes to fly again after Boeing reviewed the aircraft’s automated flight software, which caused the planes to plummet.
