(Reuters) - The head of the Federal Aviation Administration will tell a U.S. Senate panel on Wednesday that the agency will remain engaged with the Justice Department on oversight of Boeing.

FAA Administrator Mike Whitaker will tell the Senate Permanent Subcommittee on Investigations that the agency will "expeditiously provide notice, in real time, of any activities that may be criminal so that DOJ can take any action they deem appropriate," according to written testimony seen by Reuters.

Boeing agreed to plead guilty plea to a criminal fraud conspiracy charge and pay at least $243.6 million in July after breaching a 2021 agreement with the U.S. Justice Department, according to a court filing.
