The voices of the crew, key to the investigation that complicates the task of Boeing

ADDIS ABABA – The last minute survey
Ethiopian Airlines Flight 302 focused on the secrets of the Cockpit Voice Recorder today, while Boeing and the global aviation industry eagerly awaited the results.

The voices of Captain Yared Getachew and First Officer Ahmednur Mohammed could reveal the causes of the Boeing 737 MAX crash on March 10, whose resemblance to another disaster involving the same model in Indonesia in October sparked serious concern in the whole world. In both disasters, 346 people lost their lives.

The black box data was downloaded to France, but only Ethiopian experts responsible for the survey listened to the dialogue between Getachew, 29, and Mohammed, 25. The data reached Addis Ababa on Tuesday, sources close to the survey told Reuters.

Experts believe that the new Boeing MAX automated system, intended to stabilize the aircraft by lowering the nose when it detects an overly sharp angle of attack, could have played a role in both incidents, preventing pilots from taking over the aircraft control of ships while they were rushing.

The two tragedies occurred minutes after take-off, following irregular flight paths and a loss of control reported by the pilots. However, every accident is a unique chain of human and technical factors, experts said.

The investigation focuses on the prestige of Ethiopian Airlines, one of Africa's most successful aerospace companies, and Boeing, the world's largest aircraft manufacturer and the largest US exporter.

Legislators and security experts question the details with which regulators looked at the MAX model and the quality of pilot training in new systems. At the moment, more than 300 in-service MAX devices have been tied up and deliveries of some 5,000 more – valued at more than $ 500,000 million – are being discontinued.

The pressure on the Chicago-based company grew after learning that federal prosecutors and the US Department of Transportation were badyzing how the MAX model had been developed, according to two people familiar with the process.

The Department of Justice is currently evaluating Boeing's oversight by the Federal Aviation Administration (FAA), said one of the sources. In addition, a federal grand jury has badigned at least one subpoena to an entity involved in the development of the device.

The MAX, which achieves fuel savings of about 15%, has been developed to be put into service in 2017, following the successful launch of the latest model from its main competitor, the company. Airbus A320neo.

After Ethiopia, France and the United States pointed to the parallel with the accident that occurred in Indonesia, a person familiar with the investigation said that the black box data show that "l & rsquo; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; "Angle of attack" of the aircraft of Ethiopian Airlines was "very similar" to Lion Air.

The angle of attack is a fundamental flight parameter, which measures the degrees between the airflow and the wing. If it is too high, it can cause aerodynamic problems in the plane.
