The 143 so-called "classic" Boeing 737s, of the old generation, built between the 1980s and 1990s, will have to be inspected by the American aircraft manufacturer.
The US Aviation Regulator (FAA) has asked Boeing to check for a cable problem that may not be detected by the computer of the autothrottles that manage the aircraft's thrust.
According to the FAA, this could "result in the loss of control of the aircraft.
A preliminary report from the Indonesian Transport Safety Agency released in February after the crash of a Sriwijaya Air Boeing 737-500, which crashed off the coast of Indonesia on January 9, crashing a few minutes later its takeoff from Jakarta killing 62 people, had reported an "anomaly" of these autothrottles.
Even if since then, the investigation underway into the accident shows that it is "highly improbable that the accident resulted from the latent failure of this cable", according to the FAA, it nevertheless considers that this inspection is "necessary to remedy To this danger.
The 737 MAX should fly soon
However, this inspection does not concern the Boeing 737s of subsequent generations, nor the 737 MAX, the examples of which were immobilized for twenty months following two fatal accidents.
On this last type of aircraft which is experiencing many setbacks, in April, the Federal Aviation Administration asked the 16 companies operating 737 MAXs to no longer fly them due to an electrical problem. On this file, Boeing has just obtained the green light from the FAA to fly these planes. "After getting the final FAA approvals, we issued service bulletins for the affected fleet," Boeing said, saying new deliveries will be able to resume. 400 aircraft awaiting delivery, according to Greg Smith, Boeing's chief financial officer.
To bounce back and while Airbus begins to emerge from the crisis, the American aircraft manufacturer is betting precisely on the return of deliveries of the 737 MAX. In the first quarter, Boeing recorded a net loss of $ 516 million, more than three times compared to the first quarter of 2020 ($ 1.7 billion).
