An Air Canada Boeing 737 Max ferry flight to Montreal was diverted earlier this week due to an engine problem in Arizona, the airline said on Friday.
Pilots on Air Canada Flight 2358 received an engine alarm shortly after taking off from Marana, Arizona, Tuesday, the airline said. The airline had 737 Max jets stored there after the planes landed worldwide after two fatal crashes in March 2019.
"As part of normal operations in such situations, decided to turn an engine off," and diverted to Tucson, Air Canada said. The flight carried three crew members and no passengers. The plane stays in Tucson.
Boeing declined to comment and referred questions to the airline.
The Belgian aviation site Aviation24.be said the aircraft had a "hydraulic low pressure indicator". Air Canada did not immediately respond to further requests for comment.
US authorities lifted the ban on the aircraft last month after Boeing made changes to the software involved in both crashes and addressed other concerns. Canadian officials approved design changes to the aircraft last week.
