Canada introduces additional requirements to allow return to service of Boeing 737 MAX
18 January 2021

On January 18, 2021, Transport Canada issued an Airworthiness Directive for the Boeing 737 MAX which outlines the required modifications to be made to the aircraft prior to a return to service in Canadian airspace. This concludes the department’s review of the aircraft.

In addition to all reviews, and to provide additional assurances that all measures are in place, an Interim Order that indicates Transport Canada’s expectations and requirements for additional training for crew members was also issued for operators. It is complementary to the design and maintenance requirements of the Airworthiness Directive.

As a final step in this process, Transport Canada will lift the existing Notice to Airmen (NOTAM) which prohibits the commercial operation of the aircraft in Canadian airspace on January 20, 2021. This will allow for the return to service of the aircraft in Canada.

U.S. – Canadian differences
The Canadian design changes for the Boeing 737 MAX, compared to the U.S., will include an enhanced flight deck procedure that provides the option for a pilot-in-command to disable the “stick shaker” when the system has been erroneously activated by a failure in the angle of attack sensor system. This feature will effectively reduce pilot workload given what has been learned from the two tragic accidents, and has been fully evaluated by Transport Canada’s flight test pilots.
There will also be differences in training including that associated with the enhanced flight deck procedure.
