Addis Ababa, Ethiopia:
Ethiopia's investigation into the crash of Ethiopian Airlines last year showed that Boeing had not trained the 737 MAX sufficiently and that the critical flight software was faulty. This emerges from an interim report published on Monday.
The crash of the Boeing 737 MAX in Nairobi six minutes after takeoff on March 10, 2019 killed all 157 people on board and triggered the worldwide founding of the MAX in the worst crisis in Boeing history.
A Lion Air 737 MAX crashed in Indonesia in October 2018, killing 189 people when it crashed shortly after leaving Jakarta airport.
In both accidents, there were uncontrolled drops in the nose of the aircraft in the moments before the plane crashed. Investigators have blamed the model's anti-stall flight system, the Maneuvering Characteristics Augmentation System (MCAS).
A preliminary report by Ethiopian investigators released last April said flight 302 crew had repeatedly followed Boeing's recommended procedures but could not regain control of the jet.
The new interim report released on Monday states that the design of the MCAS system "has made it susceptible to unwanted activation". In particular, the report points to the fact that the system could be activated by a single measurement of the angle of attack sensor.
The displays measure the angle of the aircraft to oncoming air to warn of impending stands.
The report also said that Boeing's training courses for the 737 MAX were "found to be insufficient."
It is recommended that training simulators must be able to simulate scenarios in which the sensor fails.
The new interim report was released one day before the one-year anniversary of the crash.
Relatives of many victims from more than 30 countries have flown to Ethiopia and are expected to attend a ceremony at the crash site on Tuesday.
Last week, a US Congress committee said Boeing had made mistakes and withheld information about the 737 MAX, and federal regulators had failed to ensure proper surveillance, resulting in a "fundamentally faulty" aircraft.
