Boeing Commercial Airplanes vice president of marketing Randy Tinseth expects to see “a fairly orderly sequence” of certification of the 737 Max by the world’s aviation authorities, notwithstanding concerns expressed by Airbus CEO Guillaume Faury and International Air Transport Association head Alexandre de Juniac about a “dealignment” of regulatory agencies resulting from the twin crashes and uncoordinated grounding of the new narrowbody. Although Tinseth acknowledged the absence of the typical unanimity among international regulators at the beginning of the re-certification process as several authorities indicated they will set their own terms and conditions, he also said he has seen more coherence of opinion recently. “There are different views, but there has been a convergence over the last months,” he told AIN at Boeing’s European offices in Brussels Tuesday. “This is a welcome sign.”
