The FAA grounded all departures nationwide on Jan. 11. After an outage in the Notice to Air Mission (NOTAM) system.
“Last week’s massive flight disruption caused by contract workers. Inadvertently deleting files caused thousands of plane to be grounded.” The Federal Aviation Administration said Thursday.
On January 11, the FAA canceled all departures nationwide. After an outage in the Notice to Air Mission, or NOTAM, system.
The FAA said in a statement that the files were accidentally deleted. As contractors were “working to fix synchronization. Between the live primary database and a backup database.”
The review is described as preliminary, and the incident is still under investigation. The FAA said it found no evidence of a cyber attack or malicious intent. The NOTAM system sends pilots important information they need to fly. The system was restored later that day.
On January 11, the FAA sent a tweet at 7:20 a.m. ordering airlines to halt all domestic departures until 9 a.m.
They lifted the ground stop around 8:50 a.m. and normal air traffic slowly resumed.
The agency said to Thursday that the system has been repaired. To make it more resilient and that it will take other steps.
