WASHINGTON D.C. (CBS) — The Federal Aviation Administration (FAA) released a statement Sunday saying Boeing has informed them that some parts for the company’s grounded 737 Max passenger plane, and prior model 737 Next Generation (NG), may have been improperly manufactured. Boeing said the part known as a leading-edge slat track — a mechanism that modifies the lift and drag characteristics of the plane’s wing during takeoffs and landings — is among 148 parts from a Boeing supplier that are under concern.
According to the FAA, 32 Boeing NG and 33 Boeing Max aircraft are affected in the U.S., with the number increasing to 133 NG and 179 Max worldwide.
In its statement, the FAA said, “The affected parts may be susceptible to premature failure or cracks resulting from the improper manufacturing process. Although a complete failure of a leading-edge slat track would not result in the loss of the aircraft, a risk remains that a failed part could lead to aircraft damage in flight.”
