Experts question U.S. president’s threat to decertify new Canadian planes

Former Canadian Transportation Agency member Jean-Denis Pelletier says regulatory authority for plane certification in the U.S. rests with the Federal Aviation Administration, and encouraged the sector to stay calm in the face of the latest White House warning.
