The Federal Aviation Administration announced Friday that it has approved Boeing's design changes to the 787 battery system.
In a statement, the FAA said it will publish the directive that will allow the 787 aircraft to fly commercially once the modifications are in place.
"The FAA will require airlines that operate the 787 to install containment and venting systems for the main and auxiliary system batteries, and to replace the batteries and their chargers with modified components," the agency said in a statement.
The agency added that it will closely monitor the modifications to the 787s that are operated by U.S. carriers.
Currently, United Airlines is the only domestic carrier that operates the 787. American Airlines currently has 42 787s on order and is scheduled to receive its first 787 aircraft in 2014.
