SANTA ANA, Calif. — All planes were grounded at John Wayne Airport in Orange County Friday as staff worked to identify the cause of a power outage.
Inbound traffic was also being diverted, the airport said shortly after notifying the public of the outage around 7 p.m.
The airport advised travelers to check with their airlines regarding any delays or cancellations.
It was unclear whether the entire facility was without power. Officials said there was an outage in “the terminal,” but there are multiple terminals.
Officials initially said the airport was experiencing a “full ground stop” as a result of the outage, but issued an update shortly after 8 p.m. saying the facility was under a “full operational stop.”
“All inbound flights are being diverted, all outbound flights cancelled,” JWA said via social media. “Please check with your airline for more information including flights scheduled to depart tomorrow.”
Commercial flights were expected to remain grounded through at least 7 a.m. Saturday, airport officials said. General aviation was not affected.
The county-owned airport is on unincorporated land surrounded by Irvine, Newport Beach and Costa Mesa.
Southern California Edison’s online outage mapsaid power was knocked out for more than 28,000 customers in the Irvine area. Utility crews were working to determine the cause.
Firefighters responded to a fire at an SCE electrical vault at Jamboree Road and Michelson Drive about the same time the outage was reported, officials said.
Portions of the University of California, Irvine campus were affected by the outage, school officials said.
The vault fire “may have cause” the outage at the airport, Orange County Fire Authoritiy officials said via social media.
No further details were immediately available.
