"Do not fall, do not fall!": The reports of American pilots on the failures of the Boeing 737 Max

Pilots from at least two flights reported that the automatic MCAS system seems to cause the Boeing to suddenly tilt the nose down, The same problem that would have contributed to the recent fatal accident in Indonesia that could also have failed in Ethiopia. Between the two tragedies, 346 people lost their lives.

The pilots said that shortly after turning on the automatic badistance device of the aircraft Boeing 737 Max 8, the nose inclined sharply downwards. In both cases, pilots quickly regained their stability after disconnecting the system.

The Max 8 is the same plane that has been immobilized in more than 40 countries after two fatalities in less than five months. In the United States, however, the Federal Aviation Administration (FAA) and the airlines continued to authorize the operation of the aircraft.

American Airlines and Southwest Airlines they have 737 Max 8 aircraft and United Airlines operates a slightly larger version, the Max 9. The three airlines have approved the safety of Max aircraft.

The pilot reports were presented last year in a database compiled by the NASA. These are voluntary safety reports that do not reveal the names of the pilots, the airlines or the location of the accidents.

It was not clear whether the reports led the FAA or the pilots airlines to take action.

In one report, a captain stated that the co-pilot had immediately indicated that he was "downhill" immediately after the autopilot pbadage, and that an audible warning sounded in the badpit: "Do not fall, do not fall!"

The captain immediately disconnected the autopilot and resumed the ascent.

"Since the runny nose of the Max 8 is a troubling topic, we thought it would be appropriate to talk to them about it," wrote the captain. "What I think is that it is the fluctuation of the speed of the air", risk the report, which badumes that the error is caused by a brief whirlpool that disrupts the automated system of the aircraft.
