Boeing finds wing defect, including among some MAX

Boeing announced Sunday that some of its medium-haul 737s, including the 737 MAX 8, could have a defective wing part, but that there had been no reports of flight issues linked to the defect.

The American aviation giant, which has been rocked by an unprecedented crisis after its entire 737 MAX 8 fleet was grounded in mid-March, said a subcontractor informed it of problems with a batch of a part involved in deploying the wings’ leading edge.

The leading edge of an aircraft is key to takeoff and landing because it is meant to improve the wing’s drag and therefore the jet’s aerodynamics.
