Air Canada’s small Boeing Co7 737-8 was in Mexico with three crew members on its way from Arizona to Montreal.
An Air-Canada spokesman said Friday that the pilots received an “engine signal” shortly after take-off and “decided to shut down one engine.”
“The plane then turned toward Tucson, where it normally landed and left.”
The incident happened on 22 December.
The crew received a left-engine hydraulic low pressure signal and declared a pan-pan emergency before diverting the flight, Belgian aviation news website Aviation 24.be reported.
“Modern aircraft are designed to be powered by a single engine and provide our crew train for such cruises,” said a statement from Aircraft aircraft Neda.
Boeing and opera operators are investigating further to verify the 737 Max’s return from 20 months of safety grounding, but safety experts say such interruptions are common and usually go unnoticed.
The United States landed at Max ground in March 2019 after two planes crashed due to faulty sensors and design faults, which repeatedly pushed into the nose of the plane.
In the first incident, at least 189 people were killed on the Lion Air Flight JT610, Boeing 737 Max 8 jet, when it crashed shortly after takeoff from the Indonesian capital Jakarta in October 2018. In March 2019, another Boeing 737 Max 8 – Ethiopian Airlines Flight 302 – crashed en route from Addis Ababa to Nairobi. The crash killed 157 people from 35 different countries, including eight crew members.
The U.S. lifted a ban on flights on the 7,737 Max last month, with details outlined software, system and training upgrades by its Federal Aviation Administration to be completed before Boeing and airlines could pick up passengers.
In response to Reuters’ request for comment on Air Canada’s flight to Canada, a Boeing spokesman referred to Air Canada for information on the incident and made no further comment.
