AT A GLANCE
- Corrective maintenance activity will be conducted at the country's Air Traffic Management Center (ATMC) on May 3 and May 17.
- This will prompt the suspension of its operations for several hours which also means the shut down of the country's airspace.
- The corrective maintenance activity will mainly affect flights at the Ninoy Aquino International Airport (NAIA), Clark International Airport (CRK), and Mactan-Cebu International Airport (MCIA), and several flights at the other 42 CAAP commercially operated airports.
The entire Philippine airspace will be shut down for several hours on May 3 and 17 as necessary repairs and upgrades will be conducted by the government to fix the issues hounding the country’s air traffic management system (ATMS), the Civil Aviation Authority of the Philippines (CAAP) announced.

In a statement Tuesday, May 2, the CAAP said that a corrective maintenance activity will be carried out at the Philippine Air Traffic Management Center (ATMC) which will result to the suspension of its operations from 2 a.m. to 4 a.m. on May 3; and from 12 midnight to 6 a.m. on May 17.
“However, if the activity is finished earlier, the issued Notice to Airmen (NOTAM) will be lifted, and operations at the ATMC will resume as normal,” the CAAP said.
The ATMC is a facility which houses the Communications, Navigations, Surveillance / Air Traffic Management System (CNS/ATMS) that manages and supervises the air traffic activities within the Philippine Flight Information Region (FIR).
“The corrective maintenance activity is necessary to repair the Automatic Voltage Regulator (AVR), replace the Uninterruptible Power Supply (UPS), and upgrade the Air Traffic Management System (ATMS) A/B power supply,” the CAAP said.
The AVR refers to an electronic device which functions as a protection against surges as it regulates the voltage delivered to devices. The UPS, on the other hand, ensures that an equipment has a backup power supply in case of power failure.
The ATMS repair and upgrade will enable the UPS and AVR to serve as “each other’s backup in case the other power supply encounters a problem,” the CAAP noted.
The CAAP said that the corrective maintenance activity will affect flights at the Ninoy Aquino International Airport (NAIA), Clark International Airport (CRK), and Mactan-Cebu International Airport (MCIA), and several flights at the other 42 CAAP commercially-operated airports.
“The CAAP has already coordinated with and advised concerned stakeholders such as air carriers and airport operators Manila International Airport Authority (MIAA), Luzon International Premiere Airport Development Corp. (LIPAD), and GMR–Megawide Cebu Airport Corporation (GMCAC) in advance regarding the intended corrective maintenance activity,” the CAAP said.
“Mitigating measures and flight schedule adjustments have been discussed with stakeholders to ensure the smooth conduct of the imperative maintenance activity,” it added.
It can be recalled that the Philippine airspace was shut down on New Year’s Day, January 1, when the ATMC was hit by a power outage due to the malfunctioning of its equipment. The incident affected nearly 300 flights and around 65,000 passengers.
This was followed by a power outage at NAIA Terminal 3 on Labor Day, May 1, from 1:05 a.m. to 8:46 a.m. which affected around 50 flights and 9,000 passengers.
The CAAP assured the public that operations at the ATMC will resume as normal once the maintenance activity is completed.
“We apologize for any inconvenience this may cause and appreciate your understanding and cooperation in ensuring the safety and efficiency of our air traffic management system,” it said.
