B-737 Max: today official plane crash report in Indonesia
A series of errors would have led to the accident
A series of errors would have led to the crash of the Lion Air B-737 Max aircraft in October last year, with the death of 189 people (see AVIONEWS) as stated in the official report.
Indonesian investigators would find some flaws in the aircraft, one of the pilots would not be familiar with the procedures, 31 pages in the aircraft maintenance log would have been missing.
In particular, as already communicated to the relatives of the victims on October 23, the Maneuvering Characteristics Augmentation Software (MCAS) which regulates the structure of the horizontal stabilizer to lower the nose of the aircraft when it detects that the aircraft is in imminent danger, it would be based on a single Angle of Attack sensor (AoA) wrongly calibrated on the Lion Air aircraft during a repair. But the crew and maintenance personnel would not have been able to identify the problem.
Today Boeing has issued a statement regarding the report: "In recent months Boeing has made significant progress in supporting the safety of the B-737 Max. The company continues to work with FAA and other regulators for certification. It has also made important operational and governance changes. These two tragic incidents continue to weigh heavily on Boeing. We have set up a $ 100 million assistance fund to meet the needs of the family and community of those affected" (see AVIONEWS).
In March, the same aircraft model was involved in another disaster, that of the Ethiopian Airlines flight which killed all 157 people on board, bringing the entire B-737 Max ground all over the world. It has led a major economic impact for both the aircraft manufacturing company and the airlines.
