Boeing announced on Sunday that some of its medium-haul 737, the version remotorisée MAX, could be a defective part on their wings, but the aircraft manufacturer stated that they did not have been informed of the problem by flight linked to this defect.
The american manufacturer, who is going through an unprecedented crisis with the grounding of the entire fleet MAX since mid-march, says he has been informed by one of its sub-contractors from a faulty batch of the mechanism to deploy the slats of the leading edge on the wings. The beak of the edge of attack of an aircraft is a very important feature for the take-off and landing because it is intended to improve the gliding of air over the wing and therefore the aerodynamics of the aircraft.

Boeing indicates that it has communicated the number of the faulty batch to the companies that they inspect the rooms in question. “If the operators are the parts of this batch, they should replace with new before putting the aircraft into service,” says Boeing. “This is a device considered critical because if the nose of the leading edge does not deploy symmetrically, there can be a differential of lift which can be dangerous, particularly in the phase of take-off and landing”, told AFP an expert in aviation, who wished to remain anonymous.

And if the nose of the leading edge does not spread out at all, the conditions of flight would be dangerous. This announcement comes while Boeing strives to get the green light from the authorities of the aviation safety in order to deliver its 737 MAX, which has been nailed to the ground as a result of two accidents a few months apart with a total of 346 deaths.
