January 1. In an incident that may have been caused by improper weight and balance onboard, an Air Canada 737 MAX 8 rotated on its own, forcing pilots to hold the nose down until the aircraft obtained sufficient takeoff speed.
The incident, noted in the Aviation Herald, occurred on December 19, 2021 utilizing a Boeing 737 MAX 8 (C-GEKX) and performing AC234 from Vancouver (YVR) to Edmonton (YEG). 166 passengers and eight crewmembers were onboard.
Rotation is the action of applying back pressure to a yoke or other control device in order to lift the nose wheel off the ground during takeoff.
When the nose rose expectedly, pilots were able to push it down and keep it down until the aircraft gained enough speed for takeoff. The incident is likely attributed to a weight imbalance in the cargo hold, though that is not clear.
