Metro Manila (CNN Philippines, May 17) — The Civil Aviation Authority of the Philippines (CAAP) on Wednesday said operations in the Ninoy Aquino International Airport (NAIA) remain normal following the completion of the critical step in its maintenance activity at the country's air traffic management system (ATMS).

CAAP Deputy Director General for operations Edgardo Diaz said the critical portion of the work was the transfer of power sources from the old uninterruptible power supply (UPS) to the standby ones. This was completed at 3:14 a.m.

Installation of the new UPS units is ongoing and is expected to be completed at 1 p.m., he added.

The two-hour maintenance activity was part of the CAAP’s efforts to improve the ATMS and prevent the Jan. 1 fiasco that affected thousands of passengers.

The Automatic Voltage Regulator was also fixed on May 3.

So far, no flights were affected after the maintenance activity was completed.

“All our flights within the 2AM to 4AM maintenance period today May 17 were able to depart and arrive,” Philippine Airlines said.

The CAAP said next up is the upgrade of its software system. Details regarding this are just being finalized with its maintenance provider, but this will definitely happen within the year, it added.
