FAA is years away from upgrading the system that grounded all US flights
The Federal Aviation Administration software that causing thousands of flight delays and cancellations is 30 years old and at least six years away from being updated, a government source familiar with the situation tells CNN.
The FAA also now says "personnel who failed to follow procedures" caused the computer system failure that triggered Wednesday's delay.
The Notices to Air Missions () database failure triggered the FAA to implement the first in more than 20 years.
Transportation Secretary Pete Buttigieg has held multiple meetings with top FAA officials since Wednesday's meltdown and "has made it very clear" he wants the NOTAM database updated much faster than the FAA's planned timeline, the source tells CNN.
"The core operating system for the database has been around since the 1990s," the source said. "Regardless of the improvements made to the system in recent years, it still has the heart of an 89-year-old man."
In its budget estimate for 2023, the FAA requested $29.4 million for its Aeronautical Information Management Program, which includes the NOTAM system. Describing the system, the administration said it needs to "eliminate the failing vintage hardware that currently supports that function in the national airspace system."
Meanwhile, the FAA is stuck addressing new technology, including drones and electric helicopters, with its outdated technology, the source said.
"We need to bring equipment online a lot faster than we are," the source said, noting a big investment is required because it's far more complicated than an over-the-air iOS update. "It's gone on for years."
CNN has reached out to the FAA for comment on updates to the NOTAM system to date and its modernization timeline.
On Thursday, the FAA said the computer system failure that triggered the delay was caused by "personnel who failed to follow procedures."
The agency says it has conducted a "preliminary analysis" into the failure of the NOTAM database.
"The agency determined that a data file was damaged by personnel who failed to follow procedures," says a late Thursday statement from the FAA that also noted operations had returned to normal. "The system was functioning properly and cancellations today were below 1%."
Earlier, CNN first reported that the computer system that failed was 30 years old and was at least six years away from a planned update, according to a government source.
The failure is expected to be a main sticking point as the FAA enters its federal funding reauthorization process — especially with the GOP now in control of the House. The FAA is already taking criticism from lawmakers on both sides of the aisle.
Airlines, fielding their own share of government criticism for , have also sounded the alarm about a lack of funding, limited staffing, and outdated FAA technology.
During a September US Chamber of Commerce event, United Airlines CEO Scott Kirby told CNN's Pete Muntean that the aviation industry should rally around the FAA following a summer marred by flight cancelations and delays.
"The FAA needs more funding," Kirby said in an on-stage interview before aviation leaders. "They need more investment for technology."
