The Boeing Company (BA) - Get Report slipped 1.07% to $317.50 in late morning trading Tuesday as the aerospace giant continued to face problems related to its 737 MAX, which was involved in a fatal air crash last month in Indonesia.

The aerospace company cancelled a conference call that was scheduled for Tuesday to discuss the 737 MAX and it was not certain whether the call was being rescheduled. 

A Lion Air Boeing 737 MAX crashed in the Java Sea on Oct. 29, killing all 189 people on board. The U.S. Federal Aviation Administration warned airlines that erroneous inputs from the anti-stall system's sensors could lead the jet to automatically pitch its nose down even when autopilot is turned off.

CEO Dennis Muilenburg denied in an email to employees Monday that the company withheld information to airlines and pilots about software changes for the 737 MAX. 

Boeing recently said it had provided two updates for operators around the world that re-emphasize existing procedures for the Maneuvering Characteristics Augmentation Systems (MCAS), which are designed to prevent the 737 MAX from stalling.

A preliminary report on the Lion Air crash will be released next week.
