The Wall Street Journal, citing anonymous people familiar with the matter, reported Sunday that a grand jury issued a subpoena to "at least one person" involved in the development of the plane. It said a prosecutor from the criminal division of the Justice Department was listed as a contact. The Journal also said that the Transportation Department's watchdog was scrutinizing the FAA's certification of the new 737 planes. Boeing had added an automatic anti-stall system to the Max jets when they went into service in 2017 that was not on older 737 aircraft. Indonesia investigators have indicated that as a possible factor in the Lion Air crash in October.
Pilots said they were not informed about the new system until after the Lion Air crash. Many were given a roughly hourlong iPad training class to transition from older Boeing 737s to the 737 Max, according to Dennis Tajer, a Boeing 737 pilot and spokesman for the Allied Pilots Association, which represents American Airlines pilots.
Boeing shares were down more than 2.6 percent in afternoon trading Monday, shaving nearly 60 points off the Dow Jones Industrial Average, as the day's biggest loser in the index.
The FAA, Justice Department and the Transportation Department's Office of Inspector General declined to comment. Boeing did not immediately respond to a request for comment.
