FAA is poised to approve Boeing’s fix for the 787’s battery system Friday, according to widespread reports and indications. Japanese officials also appear to be moving toward approval of the revamped battery system.

The Wall Street Journal, The New York Times, The Seattle Times and the Financial Times all have reported FAA could lift the 787 grounding Friday. The worldwide Dreamliner fleet, which numbers 50 in-service aircraft, has been grounded since Jan. 16 following two incidents in which lithium ion batteries failed and overheated on 787s. 

Officials from Japan’s Ministry of Land, Infrastructure, Transport and Tourism told reporters they are in the final stages of reviewing the 787 battery system fix. All Nippon Airways and Japan Airlines operated 24 of the 50 787s in service when the fleet was grounded.

The 787 would likely not return to commercial service immediately, but airlines could begin installing Boeing’s fix for the battery system once FAA gives its clearance.
