The action of American manufacturer Boeing started to fall on the New York Stock Exchange on Monday, after a door torn off in mid-flight on one of its aircraft caused the immobilization of numerous planes.
In electronic trading before the opening of Wall Street, which gives an indication of the trend to expect for the session, Boeing’s stock fell 8.3% to $228.34 at 5:25 a.m. GMT. It closed Friday up 1.66% at $249.
Friday evening, a door came off a Boeing 737-9 during an Alaska Airlines flight. The plane, which had just taken off from Portland (Oregon) with 171 passengers and 6 crew members on board, was then at an altitude of nearly 5,000 m.
In response, the American Federal Civil Aviation Agency (FAA) on Saturday requested the immobilization for inspection of some 171 planes of this model, notably affecting companies such as United Airlines, Turkish Airlines and Aeromexico.
The investigation by the American transportation safety agency, the NTSB, has just begun and no conclusions have yet been drawn.
This incident adds to a long list of setbacks for the Arlington (Virginia) group, particularly concerning this model of device.
The most serious of these were the crashes of two 737 MAXs, in October 2018 in Indonesia and in March 2019 in Ethiopia, which caused the deaths of a total of 346 people.
After these accidents, linked to the MCAS piloting software, all 737 MAXs were grounded for 20 months.
