Boeing Co.'s shares tumbled as the company pushed back on suggestions it could have better alerted airlines to a new anti-stall feature in the 737 Max jetliner involved in a fatal Indonesia crash and canceled a call with carriers to discuss the model.
No reason for the scrapped conference call was given, according to people familiar with the situation. The conversation had been slated for Tuesday morning in the U.S. and was expected to be rescheduled, said the people, who asked not to be identified about a private matter.
"You may have seen media reports that we intentionally withheld information about airplane functionality from our customers. That's simply untrue," Boeing Chief Executive Officer Dennis Muilenburg wrote in a message to employees. "The relevant function is described in the Flight Crew Operations Manual and we routinely engage with our customers about how to operate our airplanes safely."
