Did FAA contractors deleted files and inadvertently grounded thousands of flights?

In January of 2023, thousands of flights across the United States were grounded due to an FAA system outage. This major disruption to air travel raised questions about what caused the FAA’s Notice to Air Missions (NOTAM) system to go down. Many are wondering if FAA contractors accidentally deleted files, leading to the shutdown that wreaked havoc on air transportation nationwide. Investigations into the cause are still ongoing.

What is the FAA Notice to Air Missions (NOTAM) system?

The FAA’s NOTAM system communicates essential safety information to pilots, airports, airlines, and other aviation stakeholders. NOTAMs contain information about potential hazards and changes that pilots need to know before flying in a given area. This includes things like runway closures, bird hazard warnings, construction obstacles, low altitude restrictions, and more.

The NOTAM system consists of flight service specialists entering notices into a central database. This data then automatically feeds out to pilot briefing systems and other aviation operations centers. Pilots are required to check NOTAMs before every flight so they have the latest safety updates. With the NOTAM system down, pilots lost this critical pre-flight safety information.

How did the January 2023 NOTAM outage occur?

In the early morning hours of January 11th, 2023, the FAA’s NOTAM system unexpectedly went offline for over 90 minutes. During the outage, thousands of flights across the U.S. were grounded as the FAA ordered all domestic departures stopped until NOTAMs came back online around 9 a.m. Eastern.

Over 1,200 flights were cancelled that day, with thousands more delayed. The cancellations rippled out across the air system throughout the day. Major hubs like Dallas-Fort Worth, Chicago O’Hare, and Hartsfield-Jackson Atlanta were hit especially hard.

The economic impact was substantial. Estimates indicate the outage cost the economy around $640 million. Airline and airport operations were disrupted significantly. Tens of thousands of passengers had travel plans upended.

Did contractor error cause the NOTAM outage?

In the aftermath, investigations sought to determine the cause. Early reports indicate contractor error during database maintenance may have accidentally deleted key files, triggering the mass outage.

Specifically, investigators believe personnel working for a FAA contractor inadvertently removed data while working on the backup NOTAM messaging system. This corrupted the database and brought the main NOTAM system down.

The contractor involved has not yet been officially identified. However, sources indicate at least one of the companies responsible may have been Advanced Technologies & Laboratories International, Inc. (ATL). ATL currently holds multi-year contracts with FAA to maintain NOTAM database hardware.

Was there an attempt to cover up the error?

Some sources allege that after the outage, there may have been an attempt by the contractors to cover up their mistake. According to these reports, personnel working on the NOTAM backup did not follow proper protocols to log their activities. Instead, they tried to downplay the severity of the data deletion.

If true, this lack of logging and transparency would have delayed getting the NOTAM system back online. It also suggests the contractors were aware of their critical error but failed to take appropriate action right away.

However, these cover-up allegations have not been substantiated by investigators yet. The FAA continues to claim there is no evidence of nefarious intentions by the contractors. But the agency has pledged full accountability as it works to determine root causes.

How could the outage have been prevented?

Aviation experts argue there should have been much more rigorous safeguards in place to stop accidental data loss. For a mission-critical system like NOTAM messaging, best practices call for:

– Stringent access controls and activity logging for any database maintenance
– Protocols requiring multiple sign-offs before changes are implemented
– More frequent live system testing to catch issues before they cascade
– Tiered backup systems to quickly fail over in case of outages

Many are stunned such robust controls did not exist given the NOTAM system’s importance for air travel safety. The FAA maintains its IT infrastructure meets all security standards. But this outage demonstrates gaps that must now be addressed.

What is being done to prevent future recurrence?

In response to the outage, the Department of Transportation immediately ordered an after-action review. The DOT aims to issue guidance within 30 days on:

– Enhancing redundancy in NOTAM messaging
– Improving outage response protocols
– Updating contractor oversight procedures

Additionally, the FAA is convening a new review board to audit its overall IT systems resilience. Expectations are this will lead to modernization efforts that harden infrastructure defenses.

In Congress, lawmakers are demanding answers. Several hearings are being scheduled to question FAA leadership on how such a major failure could occur and be allowed to cascade so badly.

Key committee leaders argue for potential reforms to FAA information security practices, contractor management, and outage prevention protocols. Some are even calling for updated regulations to minimize future shutdown risks.

Conclusion

In summary, investigations point to contractor error during database work as the probable catalyst for the crippling NOTAM outage. This highlights concerns about FAA oversight, system testing, and IT infrastructure modernization needs.

While questions remain regarding a potential cover-up, the incident has galvanized efforts to enhance redundancy and response protocols for managing future crises. With air travel still rebounding amidst a fragile economy, the pressure is on the FAA to learn from this failure.
