President Quirino Airport

The closure was a result of a combination of economic and strategic factors. The primary reason was redundancy following the development and improvement of larger, more capable airports in the region, specifically Allah Valley Airport (AAV) in nearby Surallah, South Cotabato, and Awang Airport (CBO) in Cotabato City. These larger airports could accommodate jet aircraft and served a wider population and commercial area more efficiently, making the smaller President Quirino Airport economically unviable to maintain and operate. The general security situation in Mindanao during that era may have also contributed to the decision to consolidate air services to fewer, more easily secured locations.

The airport is permanently closed and has been completely repurposed for non-aviation use. Analysis of satellite imagery of the coordinates confirms that the former runway and airport grounds have been converted into a residential area. The land is now occupied by a housing project, with homes, roads, and other community structures built directly on the former airstrip. While the faint outline of the runway is still discernible from the air, it is overgrown and fully integrated into the local community's land use, making it unusable for any form of aviation.

President Quirino Airport was a secondary 'feeder' airport. Its main purpose was to provide air connectivity for the agricultural municipalities in the fertile Allah Valley region of Sultan Kudarat. During its active years, it handled smaller, propeller-driven commercial aircraft (such as the Hawker Siddeley HS 748 or Fokker F27 Friendship) likely operated by Philippine Airlines for short-haul domestic flights. The airport was important for the movement of government officials, business travelers, and high-value cargo, playing a role in the economic life of the municipality before the road network was as developed and air travel was consolidated to larger regional hubs.

There are no known plans or prospects for reopening the President Quirino Airport. The reopening is considered extremely unlikely to non-existent for several key reasons: 1) The physical site has been permanently redeveloped with residential housing, which would require massive relocation and demolition efforts. 2) The original economic and strategic reasons for its closure remain valid, as the region's air transport needs are adequately met by other nearby airports. 3) There is no political or economic demand for its revival.
