การใช้ทิเทเนียมจีนปลอมในเครื่องบิน Boeing และ Airbus

Some recently manufactured Boeing and Airbus jets have components made from titanium that was sold using fake documentation verifying the material’s authenticity, according to a supplier for the plane makers, raising concerns about the structural integrity of those airliners.

“Boeing reported a voluntary disclosure to the F.A.A. regarding procurement of material through a distributor who may have falsified or provided incorrect records,” the statement said. “Boeing issued a bulletin outlining ways suppliers should remain alert to the potential of falsified records.”

The use of potentially fake titanium, which has not been previously reported, threatens to extend the industry’s problems beyond Boeing to Airbus, its European competitor. The planes that included components made with the material were built between 2019 and 2023, among them some Boeing 737 Max and 787 Dreamliner airliners as well as Airbus A220 jets, according to three people familiar with the matter who spoke on the condition of anonymity because they were not authorized to speak publicly. It is not clear how many of those planes are in service or which airlines own them.

The titanium in question has been used in a variety of aircraft parts, according to Spirit officials. For the 787 Dreamliner, that includes the passenger entry door, cargo doors and a component that connects the engines to the plane’s airframe. For the 737 Max and the A220, the affected parts include a heat shield that protects a component, which connects a jet’s engine to the frame, from extreme heat.

People familiar with the situation said it appeared that an employee at the Chinese company that sold the titanium had forged the details on the certificates, writing that the material came from another Chinese company, Baoji Titanium Industry, a firm that often supplies verified titanium. Baoji Titanium later confirmed that it had not supplied the titanium. The origin of the titanium remains unclear.
