Aeronautics: These Boeing 737 MAX That Almost Did Not Take Off

The American company has asked the
US inspectors had planned last year to ground the Boeing 737 MAX Southwest Airlines after learning that the aircraft manufacturer had turned off a warning signal of his aircraft without notifying the company.

Of Boeing that could never take off. US inspectors have considered last year not to allow the Southwest Airlines Boeing 737 MAX to fly after learning that the aircraft manufacturer had deactivated a warning signal supposed to warn of certain malfunctions, said to AFP, Sunday, April 29, a source close to the file.

These employees of the Federal Aviation Agency (FAA) had discovered that Boeing had automatically disabled this signal in the 737 MAX delivered to Southwest without informing the airline. Neither it nor its pilots were aware of the changes when they began to fly the plane in 2017, told AFP a Southwest spokeswoman
builder to reactivate it following the accident of a 737 MAX 8 Lion Air which resulted in the death of 189 people on October 29 in Indonesia.

"Prior to the Lion Air accident, the signals [...] were presented by Boeing as operational, regardless of whether or not you selected the feature," said Southwest spokesperson by email. But "after the crash of Lion Air, Boeing informed Southwest that the signals were inoperable if we had not taken the option," she added.

$1 billion loss

Contacted by AFP, Boeing ensured that the warning signal would now become a basic and free feature for all customers. "This change will be made on all MAX whether they are in production or in the modification phase for those who were in service," said a spokesman for the aircraft manufacturer.

The warning signal MCAS, supposed to warn of the malfunctions of a system stalling was implicated in the crash of an Ethiopian Airlines 737 MAX 8 crashed on the 10th of March in the south-east of Addis Ababa, killing 157 people.

This air disaster resulted in ground immobilization across the planet of the 737 MAX fleet. Boeing is working on MCAS modifications to get the ban lifted, but the crisis, he said Wednesday, has already cost him $1 billion.

The bill is expected to rise, as the aircraft manufacturer will undoubtedly compensate airlines that have canceled thousands of flights until this summer and have had to expand their customer services and reservations teams.
