(MT Newswires) -- Following problems with door plugs similar to those seen in the Alaska Air 737 Max 9 incident, the Federal Aviation Administration (FAA) has required additional inspections of Boeing 737 900 ER models. This directive reflects concerns about manufacturing quality at Boeing, prompting the FAA to initiate a detailed investigation and tighten controls over the company's production processes. The impact on Boeing's share price is considerable, with a fall of 18% in 2024, making it the worst performer in the Dow Jones.
