The FAA was supposed to have adopted rules by 2019 under a 2018 federal law, but the agency has said it was required to follow procedural rules before it could impose new regulations.Īfter the hijacking of four U.S. "Every day, pilots and flight crews transport millions of Americans safely - and today we are taking another important step to make sure they have the physical protections they deserve," said U.S. Unions had urged that the rule take effect one year after publication while Boeing Co (BA.N), Airbus SE (AIR.PA) and a major airline group had called for three years. The requirements are to take effect two years from the effective date, which is expected to be in August. The FAA said the additional barrier will protect flight decks from intrusion when the flight deck door is open. The final rule, which was first proposed in July, requires aircraft manufacturers to install a second physical barrier on planes used in commercial passenger service in the United States. WASHINGTON, June 14 (Reuters) - The Federal Aviation Administration (FAA) said on Wednesday it is requiring that new passenger airplanes have a secondary barrier to the flight deck to prevent intrusions.
