Last month, the US Defense Department suspended deliveries of new F-35 jets for the US military after learning that a magnet in the jet's engine was manufactured with unauthorized material from China.
The report said the Defense Department notified Congress earlier on Friday that it completed its investigation into the issue and decided not to replace the metal component in aircraft that have already been delivered.
A spokesperson for F-35 manufacturer Lockheed Martin told Sputnik that the Defense Department is expected to announce its decision on Saturday.
The F-35 program has experienced sourcing shortage issues of certain parts for the aircraft since 2019.
