WestJet temporarily grounded a Boeing 737 Max jet that was supposed to fly from Calgary to Toronto on Friday after a warning light came on in the cockpit prior to takeoff.
Flight 658 was boarded and preparing to take off when a warning light came on.
“After a normal engine start, a standard function of the health monitoring system indicated a potential fault that needed to be verified and reset,” WestJet spokesperson Lauren Stewart told CBC News.
“This process takes time and requires a subsequent engine run, which we do not perform with guests on board [so] in the interest of our guests’ time, we cancelled Flight 658 and its return 665 (Toronto/Calgary), and we rebooked them on the next available flight to ensure a timely arrival in Toronto.”
The airline says passengers were boarded onto a 787 jet and flew as planned within the hour.
Jet in question cleared to fly again
The jet in question has already been cleared and is on track for its next flight on Sunday.
The Calgary-based airline’s fleet of 13 Max jets were grounded for almost two years after more than 300 people died in two high profile crashes of the jets, operated by Ethiopian Airlines and Indonesia’s Lion Air in 2018 and 2019.
WestJet grounded its fleet of Max jets like most airlines around the world did until earlier this month, when flight authorities cleared the jets for takeoff again.
The flight would have been the jet in question’s first flight since being approved for use again, and only the third Max flight at WestJet overall since reintroduction this week.
