WASHINGTON, Oct 8 (Reuters) - The Federal Aviation Administration (FAA) said on Tuesday it is continuing to review software changes to the now grounded Boeing 737 MAX and has no firm date for completing the effort.
The U.S. aviation regulator said in a statement it is continuing "our review of changes to software on the Boeing 737 MAX. Our first priority is safety, and we have set no time frame for when the work will be completed."
FAA Administrator Steve Dickson told Reuters in September the agency would need about a month following a yet-to-be scheduled certification test flight before the planes could return to service.
Boeing's best selling 737 MAX was grounded in March after two deadly crashes in five months killed 346 people. (Reporting by David Shepardson Editing by Chris Reese)
