Two members of the US Congress want to see clear on the decision taken by the US Federal Aviation Administration (FAA) not to continue the investigation on Boeing Group, regarding the overhaul of 737 MAX aircraft. Officially to not overlap with the investigation of the Justice Department. Now, the two officials asked the Department of Transportation's Office of Inspector General to intervene. 

The initiators of the action are House of Representatives Transportation Committee Chairman Peter DeFazio and Aviation Subcommittee Chairman Rick Larsen. According to the two politicians, FAA has not provided adequate answers regarding the monitoring of the safety of B-737 MAX aircraft, protagonists of two air accidents, which caused the death of 346 people and the grounding of all airplane models for 20 months. 

The doubts of the two parliamentarians concern above all the attention dedicated by FAA to the work of the technical pilot who had carried out the safety tests on this type of aircraft: how was it possible to approve the design of the 737 MAX and minimize the importance of the MCAS (Maneuvering Characteristics Augmentation System) safety system? "Boeing's senior managers are responsible for a culture of concealment that caused the accidents", they said.
