WASHINGTON—The Federal Aviation Administration (FAA) on Monday said it is proposing to fine United Airlines $1.1 million for allegedly conducting Boeing 777 flights without making required preflight fire system warning checks.
The FAA said Chicago-based United is believed to have flown more than 102,000 flights of its Boeing 777 aircraft between June 2018 and April 2021 that did not meet U.S. airworthiness requirements—a period of approximately 1,025 days.
