The Federal Aviation Administration (FAA) mentioned on Thursday a preliminary evaluation discovered that contract personnel “unintentionally deleted recordsdata” disrupting a key computer system and prompting a nationwide groundstop on Jan. 11 that disrupted more than 11,000 flights.
The FAA said the issue occurred while personnel were working “to correct synchronization between the live primary database and a backup database.” The FAA mentioned it “has to date discovered no proof of a cyber-attack or malicious intent.”
FAA acting Administrator Billy Nolen plans to hold a virtual briefing Friday for lawmakers and staff, who have sought details of what went wrong with a pilot messaging database that led to the first nationwide grounding of departing flights since the Sept. 11, 2001, attacks.
Last week, the agency said the computer outage of the Notice to Air Missions (NOTAM) messaging system was caused by a procedural error related to a corrupted data file. The NOTAM system provides pilots, flight crews and other users of U.S. airspace with critical safety notices.
The FAA said it has made necessary repairs to the system “and has taken steps to make the pilot message system “more resilient.”
The system outage occurred on Jan. 10, however the FAA groundstop was not issued till the next morning.
Last week, a bunch of greater than 120 U.S. lawmakers informed the FAA that the pc outage was “fully unacceptable” and demanded the agency explain how it will avoid future incidents.
Senate Commerce Committee staff have also asked the FAA to answer questions on the outage, including, “Why were airlines put in a position where they could have the option of choosing to operate when the NOTAM system was down?”
