Ninoy Aquino International Airport (NAIA) in Manila, Philippines, will undergo a security assessment by the US Transportation Security Administration (TSA).
Beginning today, the three-day assessment will include inspection of the airport's airline operations and their respective ground handlers.
TSA is responsible for carrying out security inspections at international airports that have direct flights to the US, and are served by national air carriers to ensure compliance with the safety standards set by the International Civil Aviation Organization.
In addition, the US Government agency inspects the airports identified by the department of Homeland Security as high risk.
TSA last inspected the airport in November 2013.
NAIA was voted as one of the worst in the world in 2014 by travel website Cheat Sheet.
Equipped to handle six million passengers annually, the airport currently handles 32 million.
However, Manila International Airport Authority (MIAA) general manager Jose Angel Honrado said that the airport could clear the TSA inspection as the management was constantly involved in ensuring passenger security.
Honrado said: "The results from which showed that the airport meets international standards. MIAA maintains a positive disposition that the airport will again pass the inspection."
Cathay Pacific, Philippine Airlines, EVA Airways, United Airlines, UA Cargo, Federal Express, United Parcel Service Clark, Delta, MIASCOR, Sky Kitchen Philippines Incorporated and PAL Cargo will undergo the TSA audit.
Following the TSA assessment, the airport will undergo another inspection focused on terminal systems and ramp access control, security screening, quality control, the airport perimeter, as well as the command centre and aircraft and cargo operations, reported the Journal.
The airport is scheduled to get new body scanners and install more CCTVs by 2016.
