The Federal Aviation Administration (FAA) opened a probe into Boeing and Airbus, two of the largest commercial plane manufacturers, to determine how counterfeit titanium got into their supply chains. On Friday, June 14, The New York Times reported that Spirit Aerosystems, which provides fuselages to Boeing and wings to Airbus, used titanium with falsified documentation. The probe came after inspectors reportedly found small corrosion holes in the materials.
A Spirit Aerosystems spokesperson said that it has removed all questionable titanium from the supply chain. The company performed more than “1,000 tests” to check “airworthiness.”

Meanwhile, Boeing said that it removed the parts in question from aircraft before delivery. The manufacturer also said there is no impact to the safety of its fleet.
Airbus said that it does not know how many aircraft are affected. However, tests show its planes “airworthiness remains intact,” according to the company.
Boeing issued an alert to suppliers, warning them to be vigilant when looking out for falsified documentation on parts. Federal investigators said that the aero giant alerted the agency of the problem voluntarily.
However, the FAA is still looking into who sold the fraudulently documented titanium to Spirit Aerosystems.
The FAA probe comes as concerns rise over airplane parts with false documentation entering the supply chain. Last year, CFM, a jet engine manufacturer, revealed that thousands of its engine components may have been sold with fake records from a British distributor. The revelation forced airlines to change parts on a handful of planes.
The latest investigation came after the FAA said earlier on Friday that it was looking into what caused a Boeing 737 Max jet to maneuver out of control in a “Dutch Roll.” The incident happened on a flight from Phoenix to Oakland in May 2024. The plane tilted left-to-right at the same time the nose moved up and down.
Boeing’s rough year started when a door panel blew off a 737 Max-9 midflight in January. The FAA is also investigating Boeing over whistleblower allegations that the company did not complete required inspections on its 787 Dreamliner jets.
