MANILA, Philippines — The Civil Aviation Authority of the Philippines (CAAP) on Sunday morning conducted a maintenance procedure on its navigation system, three weeks after hundreds of domestic and international flights were disrupted by a technical malfunction.
In a statement, CAAP said that a cooling fan for the second uninterruptible power supply (UPS) that is being used to power the Communications, Navigation, and Surveillance / Air Traffic Management (CNS/ATM) System at its Air Traffic Management Center (ATMC) was replaced.
“After the successful maintenance activity which was undertaken by CAAP engineers and the equipment’s service provider, operations at the ATMC returned to normal at 6:09 a.m, with the NOTAM subsequently being canceled at 6:16 a.m,” it said.
A total of nine flights were affected at the Ninoy Aquino International Airport’s taxiway for departure, while 38 flights “waited for clearance delivery during the short outage that was necessary to complete the maintenance activity.”
CAAP’s air traffic system shut down following a power outage on Jan. 1, 2023.
The technical failure resulted in hundreds of flight being diverted, canceled, or delayed, which affected around 65,000 passengers.
