Dublin Airport radar system brought down by faulty network card

Travelers warned to expect delays during peak times as better system monitoring tools are installed

LONDON -- A faulty network card brought Dublin Airport to a halt last week, causing the collapse of the radar system.

Dublin Airport is working with air traffic management (ATM) system supplier Thales to tackle a serious radar system malfunction after the error delayed numerous flights.

Passengers were left waiting at the airport for as long as two hours after a July 9 failure in the radar system.

"Thales ATM confirmed the root cause of the hardware system malfunction as an intermittent malfunctioning network card which consequently overcame the built-in system redundancy," the Irish Aviation Authority (IAA) said in a statement.

Thales ATM also confirmed that the network card had caused system malfunctions since June 2, the authority said.

"Thales ATM stated that in 10 similar Air Traffic Control Centres worldwide with over 500,000 flight hours (50 years), this is the first time an incident of this type has been reported," the aviation authority said.

Dublin Airport has warned travelers to expect delays for several weeks as engineers install better system monitoring tools.

The aviation authority said air traffic control is now "generally meeting demand," but that delays will still occur at peak times until the system is returned to full function.

"To minimize the possibility of such a recurrence, the IAA has installed additional system monitoring tools and proposed an enhancement to the failure recovery system," it added. "The IAA is continuously monitoring the system performance." It said it will slowly add capacity to the system, and will not operate it to its limit until testing is complete.

Thales was not available for comment.
