Investigators examine engine parts from the ill-fated Lion Air flight JT 610, after they were recovered from the bottom of the Java Sea Boeing on Tuesday insisted it would share any information to emerge from an investigation into the crash of one of its newest planes in Indonesia last month, amid reports a telephone conference with its customers had been canceled.
US media reported that the canceled conference between Boeing and client companies was meant to address questions surrounding control systems on the Lion Air 737-MAX.
"Boeing has been - and continues to - engage with our customers," a spokesman for the US aircraft manufacturer told AFP.
"We continue to schedule meetings to share information."
Last month's crash killed 189 people when Lion Air flight JT 610 plunged into the Java Sea on October 29, less than 20 minutes after leaving Jakarta on a routine flight to Pangkal Pinang. There were no survivors.
Media reports said Boeing CEO Dennis Muilenburg had sent a message to staff on Monday insisting that the company leadership had not concealed any information relating to the Maneuvering Characteristics Augmentation System (MCAS) which was designed to prevent the aircraft stalling.
"I don't have any additional comment on the memo," the company's spokesman told AFP.
"The problem of the MAX is linked to its hybrid design," an aeronautics expert, who asked not to be identified, told AFP.
"Boeing had to make a number of choices, and above all compromises in the area of avionics and the flight command system during development of this plane," he said.
The expert added the main problem with the MAX was the marriage of older and newer control systems which were installed to make it competitive with rival manufacturers.
"That could have been a not insignificant factor in the response of the crew," who seem not to have understood the role of the MCAS in the chain of events that led up to the crash.
Last week, a US airline pilots union, the APA, said that companies and pilots had not been informed of certain changes in the aircraft control system.
It said it had passed on new piloting directives to flight crews regarding possible erroneous information about a so-called "Angle of Attack" sensor that could have been linked to the Lion Air crash.
