US Federal Aviation Agency (FAA) inspectors have planned to ban the theft of part of the Boeing 737 MAX in 2018, after discovering that the American aircraft manufacturer has turned off the warning signal intended to warn malfunctions of the MCAS anti-stall system.
These FAA inspectors were in charge of controlling the airline Southwest Airlines which had a fleet of 34 aircraft in service at the time, a source close to the file told the press, adding that they had planned to nail down the ground of planes to determine if the pilots needed additional training.
A measure subsequently dropped without it reaching senior officials of the federal aviation agency, according to information from the Wall Street Journal.
Boeing chose to make the light alert signal optional and optional, after Southwest asked the builder to reactivate it following the crash of a 737 MAX 8 from Lion Air in Indonesia that killed 189 people on the 29th last october.
Boeing turned off the signal in the 737 MAX aircraft delivered to Southwest Airlines without informing the airline or its pilots, an airline spokeswoman said.
MCAS was also implicated in the crash of an Ethiopian Airlines 737 MAX, which crashed on March 10, southeast of Addis Ababa, leaving 157 people dead, causing the fleet world of the 737 MAX.
