Air Canada announced that it is suspending all 737MAX flights until July 1st, meaning that the aircraft will be out of service another three months, at least for one airline, while improvements to the software and MCAS system are made.

This is the first airline to cancel MAX flights for a lengthy period, and provides an initial indication of how long the recertification of the aircraft could be.  The last time an aircraft was grounded, the Boeing 787, it was for a similar period of just over three months until a revised battery fire containment system could be installed.

But today, the environment has changed.  Just as there was a non-uniform grounding, there could be a non-uniform return of the aircraft to service, as various regulatory agencies want their own testing and recertification processes, rather than rely on reciprocity.  We fully expect different timing for different regulatory entities in this case, some of which may be longer than others.  The era of the world relying on the FAA

as a global safety authority appears to be over.
