Many pilots have complained about the problems they encountered with flying Boeing 737 Max 8 months before the accident happened with Ethiopian Airlines. After two accidents occurred in just a few months, many hundred people were killed, the 737 Max was banned from flying wide and the story behind the errors related to the flight and control system is gradually being revealed. br />
US regulators recorded at least 5 complaints in the past few months with the 737 Max, a captain even criticizing flight documentation is incomplete and flawed that could cause an accident. These complaints are mostly about autopilot (autopilot) on Max 8, which caused two accidents with Lion Air in October and Ethiopian Airlines a few days ago.
Data from the black box of 610 flight by Lion Air showed that the aircraft was in a position to put its head down several times, mainly due to the error related to the sensor of the automatic system. Ethiopian Airlines CEO Tewolde GebreMariam said there was a similarity between the two collisions that killed all passengers and crew on the two flights.
A pilot said that this error occurred during the aircraft taking off. When the autopilot mode is activated, the nose of the aircraft immediately descends and the aircraft’s warning system emits a dangerous signal. This error only goes away when the autopilot system is turned off. In November, a Max 8 pilot said they were allowed to continue flying without adequate training or instructing system differences compared to other aircraft. Even the auto power system automatically fails and only when the pilot adjusts the engine manually.
After the two very serious accidents mentioned above, Boeing is meeting a wide-ranging scandal. They immediately announced that they would update the software for the 737 Max flight system in the near future, and now many countries have banned flying with 737 Max, except the US and Canada.
