JAKARTA (Reuters) - Mechanical and design issues contributed to the crash of a Lion Air 737 MAX jet last October, according to Indonesian investigators’ briefing to victims’ families on Wednesday ahead of the release of a final report.
Contributing factors to the crash of the new Boeing Co airplane, which killed all 189 people on board, included incorrect assumptions on how an anti-stall device called the Maneuvering Characteristics Augmentation System (MCAS) functioned and how pilots would react, slides presented to the families showed.
The slides also said reliance on a single angle-of-attack sensor made the system more vulnerable to failure, and that the sensor on the aircraft that crashed had been miscalibrated during an earlier repair.
